BAE 2024 Newsletter

A Message from Dr. Chinn Better Late than Never!

As we begin a new Fall semester, I wanted to make sure we shared our story from 2024 in this volume of the “BAE Update”. We had a memorable year celebrating the excellence, accomplishments and impact of our students, faculty, staff and alumni and we did not want to miss the opportunity to capture and highlight some of the successes of our BAE family and the new areas where we work and play.

We finally made the move to the New Frontiers Agricultural Hall building, which has been nurtured by the special touch of ag engineering as told in one of the featured stories centered around our very own Drs. Randy Raper and Raymond Huhnke. Our change in administrative offices, faculty, graduate student and instructional space came with changes in several of our faculty and staff through retirement to new adventures. And while we said farewell to those who have served the department with dedication, greatness and goodwill, we welcomed Dr. Keighobad Jafarzadegan as our new water management assistant professor and Extension specialist. He is further strengthening our data-driven research expertise and impact in water resources, assessing hydrological extremes and sustainable practices. I also hope you have noticed the positive influence our new marketing and communication specialist, Jessica Busby, is having on our effectiveness in spreading the word about our great department and the wonderful things we engage in. They are introduced as our new faces in this communication.

The outstanding contributions of our faculty and alumni to our agricultural and biological engineering profession is something that should be admired. Dr. Paul Weckler retired with a bang, honored as a 2o24 ASABE Fellow during the annual international meeting in Anaheim, CA. He joins quite a few other distinguished OSU BAE faculty who have been recognized with our profession’s highest honor. We call attention to this remarkable collection of exceptional OSU faculty and alums who have been influenced by them. These well-deserved recognitions and recent faculty and staff awards are communicated in multiple featured articles within this newsletter.

Our students continue to be bright and accomplished in their scholarship, leadership and community impact. They remind us every day what a joy it is to be part of their education, career development and OSU experience. Please enjoy reading about some of these outstanding individuals and their activities in the pages that follow.

I cannot effectively express how amazing our donors are and how fortunate our department is to have alumni and friends that are willing to give back and feed our growth and achievements, quality programs and future opportunities with their generosity in time and gift giving. We are grateful for our interactions with the students, emeriti faculty and their families, alumni and friends throughout the year and the contributions of our highly engaged BAE advisory committee. We strive to make you proud of our people and programs and thank you for your continued support.

As we share our professional and personal stories from the past and in the future that shape our stepping stones and the various paths that we walk, I hope that in the days to come you experience many moments that expose you to the joys of life. Be well and Go Pokes!

Building Friendship: Agricultural engineers work together to serve the future of OSU Agriculture

When presented with a job opportunity to move his family from Booneville, Arkansas, to Stillwater, Oklahoma, in 2012, Randy Raper called lifelong friend, Raymond Huhnke, for some advice on the new position.

Little did he know a decade later the phone calls between these friends would be more than just friendly advice.

In 2021, Raper called Huhnke for help planning and overseeing construction activities related to the building of the new Agricultural Hall.

“Ray and I have worked together on a number of things over the years,” Raper said. “When Ray was starting to talk about retirement I went to him and asked ‘Would you be willing to work with me on this process on a part-time basis?’ and he agreed.”

Even though Huhnke retired in January 2021, 6

he continued making contributions to the Ferguson College of Agriculture as an engineer for Agricultural Hall, assisting in any way he could to help with the fine details related to design, layout and construction of the new facility, he said “I worked with Randy in addressing what has been and what needs to be done to make the great facility we have now,” Huhnke said.

The pair worked together to create a space for students, faculty and staff to call home while serving as the coined duo in each meeting and stage of development for the new Agricultural Hall.

“Ray has been a tremendous help in terms of being a second set of eyes and ears in the room, going back and forth making sure we heard the same things,” Raper said.

Serving the Future When many reminisce on their time in 4-H, they catapult to a memory. They may not have realized it then, but they were learning irreplaceable teamwork and leadership skills.

For Raymond Huhnke, 4-H is where he developed these skills that became vital to his career, he said.

“My passion to help others goes back to my youth,” Huhnke said. “4-H provided me with my thought process. It allowed me to work with a variety of different members, even the younger 4-H members, to give them insights as to how they could put their best work into their projects. It has always been a team effort to make things better.”

With a goal to make the agricultural industry better, Huhnke started his education at Purdue University where he obtained a bachelor’s degree in agricultural engineering.

Huhnke then went on to gain a master’s degree from the University of Illinois and a doctoral degree from Iowa State University, both in agricultural engineering.

In 1980, Huhnke started his journey at Oklahoma State University as an assistant professor and agricultural extension engineer. Huhnke spent the first 35 years of his career focusing on OSU Extension services.

“I have probably known Ray longer than anyone on this campus,” said Ron Elliott, retired agricultural engineer and emeritus head of the OSU Department of Biosystems and Agricultural Engineering. “He is knowledgeable in a wide variety of areas and is a solid engineer.”

Huhnke and Elliott met at the University of Illinois through the agricultural engineering master’s program. They reconnected when Elliott joined the OSU faculty in 1981.

At the beginning of his time at OSU, Huhnke worked on the development of farm structures.

He has had many successes in this area and is widely known for his work in corral and beef working facilities, Huhnke said. Huhnke helped develop facilities to keep animals and handlers safe while still being efficient, he said. Huhnke recorded a series of videos to inform children

about animal handling and farm safety as well as led demonstrations of his work to help farmers to make informed decisions.

Huhnke was the driving force for round-bale storage research, Elliott said. Huhnke saw the financial impact these structures and processes could have on rural farmers, which led him to pursue these projects, he added.

“I branched out and was involved in roundbale storage because hay is one of the top five agricultural commodities in the state, valued at about $600 million,” Huhnke said. “If we could save 10% of the hay being stored, that’s a significant amount of money that producers could save or invest.”

In 2002, Huhnke saw the need for a program called AgrAbility, which allows agricultural workers with disabilities to keep doing the things they are passionate about, he said.

“AgrAbility is a program that reaches out to and helps disabled farmers,” Elliott said. “Maybe somebody has great difficulty going up the steps into ­­a tractor or operating equipment and they still want to farm. They have some issues to overcome, and some special adaptive devices can help with that.”

AgrAbility was just one of the many projects Huhnke was involved in to help farmers keep doing what they love, he said. Huhnke often worked to combine field demonstrations with applied research.

“I wanted to demonstrate things out in the field that would allow me to not only capture the attention of the ranchers and the farmers as to what opportunities there were but also to gain some research data that could be shared within the state and within the region,” Huhnke said.

Huhnke made major strides in the biobased energy industry, said Danielle Bellmer, Ferguson College of Agriculture assistant dean of academic programs. Huhnke and Bellmer worked together during the initial stages of the Biobased Products and Energy Center.

This center conducts research on bioenergy and biorefinery operations used to make these 7

processes more sustainable, Bellmer said.

“We started a biofuels research group here at OSU,” Bellmer said. “Huhnke and I worked on it a lot together, and then he became the director of the Biobased Products and Energy Center.”

During Huhnke’s time with the center, he saw the need for federal funding of these projects. He gathered a cohort of students, professors and researchers to help him write grants.

“He helped form a productive, collegial group of researchers that worked well together as a team,” Bellmer said. “There were faculty from plant and soil sciences, agricultural economics, and biosystems engineering. We collaborated on grants and projects.

He would organize and lead the group, saying, ‘Here’s a new grant opportunity. Who wants to participate?’”

The need for grants and the developing research led to researchers from South Dakota State University to reach out to Huhnke and his team. This group wanted to compare regional research efforts in biobased energy, Bellmer said.

Together, SDSU and OSU created the Sun Grant Initiative, a collaborative effort between landgrant universities to research biobased energy.

The SGI is federally funded through the U.S. Farm Bill. When the SGI first became federally funded, Huhnke served as the associate director of the Sun Grant Program at OSU. “We would have small to large proposals submitted to us, and then, we would have a team of experts come in to evaluate those proposals to provide funding through the selected projects within this region,” Huhnke said.

These projects have added an estimated $174 million to the regional domestic product as well as the nation.

In 2017, Huhnke’s contributions to OSU Agriculture led to his promotion to Regents professor, the highest rung on OSU’s academic ladder.

Even though Huhnke retired in January 2021, he still has a passion for making OSU the best it can be, he said, and credits the teamwork and leadership skills he learned from his youth for his career success.

Directing the Vision

In the ninth grade, Randy Raper was asked by a teacher to write an essay on what he wanted to be when he grew up. Little did he know the answer to the question would change his life.

“I wrote the story on being an agriculture engineer,” said Raper, assistant vice president of facilities for Oklahoma State University Agriculture. “I turned it in, and the teacher said it was a great story. However, she said, ‘You will never be an agriculture engineer. You will be an agricultural engineer.’”

As a native of northern Alabama, Raper said he had waited his whole life to attend Auburn University and make his ninth-grade dream a reality. However, when persuaded by a buddy to tour Mississippi State University, his plan was altered overnight, he said.

“We went there and visited with the department head,” Raper said. “Before we left that day, he had convinced both of us to go to Mississippi State and go into agricultural engineering.”

As a new student of MSU, Raper was determined to work hard and find a way to pay for school while gaining experience in his hopeful career path, he said.

“In my first semester, I got a call from my dad who said I had a letter at home and I needed

to check into it,” Raper said. “The letter said John Deere was interviewing on campus the next day and they were looking for agricultural engineers.”

Raper interviewed with John Deere and received a position in a cooperative program to alternate one semester at school and one semester at John Deere. He spent more than two years in their collegiate program with hopes of continuing in a path to full-time employment with the company, he said.

“Near the end of the program when I would have been offered the job in the early 1980s is when jobs were really difficult to find,” Raper said. “John Deere eliminated the program. No one got a job, so I decided to look at graduate school.”

Raper’s journey to higher education led him to Iowa State University where he earned both master’s and doctoral degrees. His career path led him back to northern Alabama then to Booneville, Arkansas, working with the U.S. Department of Agriculture before a call came to interview at OSU. Raper joined OSU Agriculture in 2012 as an engineer to evaluate property, buildings and research areas for enhancement or maintenance to ensure all spaces maximized the learning experience, he said.

In 2017, Raper entered the conversation about what it would take to build a new Agricultural Hall.

As a professor of biosystems and agricultur-

al engineering with experience in agricultural research, he said his goal was to find solutions and implement a space for generations of students to enjoy.

“My background is in research,” Raper said.

“I knew I could do that with my eyes closed, but this was a new challenge, working in construction.”

In the early stages of development, Raper sought a variety of perspectives to ensure the new Agricultural Hall was built on the needs of its inhabitants, he said.

“He played a role in bringing faculty to the table and getting staff involved,” said Thomas Coon, retired vice president and dean of OSU Agriculture.

Raper had observed a trend of faculty members outlasting the department leadership in terms of years in their respective roles, so he created a committee of professors and staff to suggest features necessary for a new space with productivity and practicality, he said.

“I really thought if we were going to do something like this that would be beneficial,” Raper said. “I felt it ought to be faculty-driven.”

Raper played a vital role in facilitating meetings with the appropriate professors and staff with the team of architects, said George Winters, principal architect behind the development of the new Agricultural Hall.

This allowed for the necessary insight on the 9

requirements to create a functional space for students, faculty, and staff, Winters added.

Dr. Raper cares a lot about people,” Coon said.

“What students like about the new building is what he created for them. He wanted to make this building for students.”

With the former Agricultural Hall, now named Legacy Hall, housing few shared spaces, students would come for their scheduled class time and depart soon after.

This observation led Raper to think like a student and imagine an environment to enhance the academic experience, he said.

“He’s behind the scenes from a student perspective, but everything he did was student-focused,” Coon said.

Raper wanted spaces for student organizations and faculty gatherings as well as places to cultivate conversations and welcoming spaces to lounge, catch up or focus on the next task at hand, he said.

“All of the sudden, I’m seeing something tremendously rewarding, the way students are us-

ing the spaces,” Raper said.

The biggest difference between the new Agricultural Hall and the previous building is the designated areas for students to flourish, a credit to the design and contributing conversations from those who occupy it, Raper said.

“It all goes back to his character and his mission,” Winters said. “He is committed to the university, to its students, to its faculty and to the success of this building.”

For Raper, success is ensuring the space designed for students and faculty continue to be well used, he said.

As he lives out his ninth-grade dream of being an agricultural engineer, Raper said he will continue to apply the guiding principle of being people-focused for each upcoming project and development.

Making the Water Well

The average depth of a water well in Oklahoma is 175 feet deep, according to Oklahoma State University Extension. However, not all wells are equal.

OSU Extension in conjunction with the Oklahoma Water Resources Center provides free well water screenings to counties across Oklahoma. Kevin Wagner, director of OWRC, began this project in 2018.

The idea came to Wagner when he collected data from Oklahomans about water issues, he said, and their most common concern was access to safe drinking water.

“Helping people understand their water safety is the goal of this project,” Wagner said.

To create the water well screening project, Wagner worked with Karen Hickman, environmental science professor, and Tyson Ochsner, plant and soil sciences professor.

Anyone can bring well water samples for free screenings to collection events, which occur at fairgrounds, OSU Extension offices and libraries.

The only thing required of residents is to complete a contact sheet with their personal information and bring water samples in a new plastic water bottle with their names, location of where the water was drawn, and the time of collection clearly labeled on the outside of the bottle.

The samples are taken to the Biosystems and Agricultural Engineering lab on OSU’s Stillwater campus to be tested for E. coli, hardness levels, nitrate levels, total dissolved solids, arsenic and pH levels.

In the lab, James Lee, biosystems engineer-

ing junior, and Kaylin Hall, civil engineering sophomore, test the collected water and record the data.

After the data has been recorded, Jeff Sadler, water resources specialist for OSU Extension, reviews the test results and notifies well owners of their results via email.

Participants can expect results from the screening to be in their inbox within seven days of collection.

Sadler also provides participants and OSU Extension educators with educational materials after they have received their results. Sadler and his undergraduate students have conducted in-person meetings where residents can ask questions and learn firsthand how to keep their drinking water safe, Sadler said.

“We provide well owners with guidance and resources,” Wagner said.

The Rural Renewal Initiative at OSU has provided additional help by assigning student scholars to the project. Rayna Ellison, environmental science alumna, worked in southwest Oklahoma and collected water samples when the program was in the beginning stages.

“Through Rayna’s data, we found the nitrate levels were relatively normal in the samples submitted,” Ochsner said. “What surprised me to some extent was the total coliform and E. coli levels. They were concerning and unexpected.”

These results provided even more of an increased need for the program, Ochsner added.

Since the initial pilot phase, well water screenings have taken place in many areas 11

Land-Grant Award for Excellence Dr. Jeff Sadler The achievements of our very own Jeff Sadler, BAE Assistant Professor and Extension Specialist in water resources engineering, were recognized when he received the Land-Grant Award for Excellence during the Oklahoma State University Awards Convocation ceremony in December.

This award was established to recognize a faculty member whose exemplary contributions promote the land-grant mission of Oklahoma State University.

Dr. Sadler started his faculty career in the department in July 2022 and within a short period of time has made significant contributions to scholarly excellence and impact.

He has brought critical expertise to OSU in the area of data science and artificial intelligence and as a well-balanced faculty member is consistently promoting those areas that help us achieve our land-grant commitments—student success as a result of mentorship and offering enrichment experiences with undergraduate research, innovative and hands-on instruction and scholarship of teaching; developing ideal graduates who are prepared professionally and have an appreciation for emerging technologies; and advancing our engineering knowledge and capabilities to solve sustainability and community water challenges through integrated research and Extension work.

The excellence in his outreach programming and research has also been recently recognized by others positively impacted by his innovation, service, and dedication—Dr. Sadler earned the 2024 Rural Health Educator of the Year Award from the OK Rural Health Association, and the 2024 Early Career Research Excellence Award from the International Environmental Modelling and Software Society (iEMSs). Congratulations, Dr. Sadler!

of Oklahoma. One of the more popular collections took place in Alfalfa County in the spring of 2022.

“We collected over 100 samples in Cherokee, Oklahoma,” Wagner said.

Citizens specifically asked to have the sulfate levels tested, Wagner said. At the time, the lab had no ability to measure sulfate, so they worked to locate a test. As suspected, the water collected in Alfalfa County was high in sulfate, Wagner continued.

Water screenings have taken place in about a dozen counties across Oklahoma, and 24 water well testing events are planned for 2024. Each event will include drinking water quality education programs and regional water quality health assessments.

“We find a lot of samples have bacteria,” Wagner said. “We recommend the owners get a sample retested by a certified lab and find another source of drinking water.”

For some issues, owners can implement ways to improve their water quality, he said.

For example, if a water sample has high amounts of nitrates, the owner can install specific filters.

“Everyone should have access to clean, safe drinking water,” Ochsner said. “It’s a basic human need.”

Well owners should have their water tested once a year for bacteria and once every three years for other elements, Wagner said.

Ochsner said he appreciates the work Wagner is doing to ensure Oklahomans know their drinking water is safe.

“My goal is to reach every county, informing them about water quality potential,” Wagner said.

Innovation at the Intersection “A world where all have the food, water, energy, fiber, and safe environment needed to thrive,” - Vision Statement of the ASABE Agricultural engineering has provided unique and impactful expertise, programs and services within both the agriculture, natural resources and engineering domains at Oklahoma State University since the turn of the century. Listed under a variety of names ranging from farm engineering and farm mechanics to agricultural engineering, the course work and required hours

for degree conferral varied throughout the first 24 years of the program. While today’s classes feature significantly less blacksmithing or carpentry and require fewer hours operating steam engines or working with threshing crews, the intentions remain the same, to further the productivity, profitability, and innovation in agriculture and life sciences through engineering and technology. At OSU, those intentions have been propelled into the future by the hard work and dedication of our esteemed faculty.

In a timeline running parallel to the development of, what is now, the Department of Biosystems and Agricultural Engineering at our university, an industry relevant society began to develop at another land-grant institution.

Beginning in 1907, the American Society of Agricultural Engineering, now the American Society of Agricultural and Biological Engineers, formally organized at the University of Wisconsin-Madison. The highest grade within this society is that of Fellow, defined by the organization as “a member of unusual professional distinction, with outstanding and extraordinary qualifications and experience in, or related to, the field of agricultural, food, or biological systems engineering.”

Nomination for fellowship requires lists of professional accomplishments, contributions of record, and references from at least six other ASABE members, in addition to 20 years of professional experience in or teaching engineering as well as 20 years of active membership in ASABE. According to Dr. Ronald Elliott, former BAE department head, emeritus faculty and ASABE Fellow, nomination to the grade of Fellow is the “recognition of a career’s accomplishments by

your peers.”

The benefits of having a historic line of faculty ornamented with Fellows is that it encourages both the students and the faculty that follow to pursue membership in professional organizations and make significant contributions to the profession.

“We have a professional responsibility to give back to the profession through activity and organization as a means to continue the legacy,” Dr. Elliott stated, emphasizing that membership serves “to continue an extension of the participation in student organizations with professionals, to in turn start establishing community outside of the collegiate experience.”

In the last 118 years of ASABE’s organizational history, our BAE department has had 17 faculty attain the rank of Fellow while in service to OSU, with an additional 4 previous faculty named while serving other institutions. The 17 faculty who have attained the rank of ASABE Fellow have a combined over 450 years of educational service to OSU, with the following individual distinctions: •6 have dedicated service as department head •4 have been awarded the classification of Regents Professor •3 have dedicated service as executive leadership in Extension operations •4 have co-founded and directed an OSU Center or major initiative that established meaningful education, research, and Extension expertise and services to Oklahoma and regional stakeholders •2 have dedicated service in administrative leadership in college operations

Prominent Leadership Roles in ASABE

In addition to our faculty fellows, the Department of Biosystems and Agricultural Engineering is honored to have had 21 departmental alumni become ASABE Fellows.

Three of these alumni would later become ASABE presidents, one of which is the organization’s current president, Sherry Hunt, pictured above.

According to Dr. Ron Elliott, 5.1% of all ASABE fellows have a connection to Oklahoma State University, either as alumni, faculty member, or both. This long-standing and rich tradition of academic success among this department’s faculty is directly reflected in the success of their former students- a testament to their continued legacy of excellence.

These Fellows have positively impacted both the department’s culture and the engineering profession.

by influencing accreditation processes to focus on outputs for both the Accreditation Board of Engineering and Technology (ABET) and the International Fire Service Accreditation Congress (IFSAC), of which he supported in development. Dr. Thomas Haan’s work and guidance on hydrology connected the university with other private and public research groups, creating strong ties to the United States Department of Agriculture’s Agricultural Research Service and Natural Resources Conservation Service.

The legacy of biosystems and agricultural engineering at OSU is deeply rooted in both innovation and service, as reflected by the accomplishments of its faculty and their recognition by professional societies like ASABE. The distinction of Fellow is not only a mark of individual excellence, but also a reflection of the department’s enduring commitment to advancing engineering for the betterment of society. Through decades of leadership, research, and community engagement, these faculty members have not only shaped the direction of the department but have also inspired future generations of engineers to lead with integrity and purpose. As we look to the future, the foundation laid by these Fellows ensures that OSU will continue to be a driving force in biosystems and agricultural engineering - where tradition fuels innovation, and excellence remains the standard.

Engineering Excellence Nearly 30 years ago, two engineers in the Oklahoma State University Ferguson College of Agriculture forged a plan to provide engineering assistance to manufacturers across rural Oklahoma. Today, their plans have expanded and continue to help hundreds of businesses throughout the state.

In 1997, the OSU Department of Biosystems and Agricultural Engineering united with the Oklahoma Manufacturing Alliance to create the applications engineering program.

BAE faculty Bill Barfield and Sam Harp founded the applications engineering program for the engineers at OSU to assist Oklahoma manufacturers with their production and economic needs, said Rajesh Krishnamurthy, senior applications engineer and program manager.

“Barfield and Harp wanted to increase the competitiveness of small- and medium-sized manufacturers,” Krishnamurthy said. “The applications engineering program was created to provide manufacturers with on-site, oneon-one engineering assistance and technology transfer services throughout Oklahoma.”

OSU’s applications engineers introduce new technology like collaborative robots to manufacturers across the state. The cobots work side-by-side with humans in assembly lines to complete tasks and increase productivity, Krishnamurthy added.

The partnership between applications engineers and the OMA makes short-term, project-related services available to manufacturers through resources of OSU’s applications engineering program, said Joe Epperley, OMA communications director.

“The Oklahoma Manufacturing Alliance exists to help small- and medium-sized manufacturers become more efficient and more successful through technology integration and supply chain management,” Epperley said. “This partnership with the applications engineering program was a big need for the manufacturers who didn’t have access to these types of engineering services.”

Applications engineering has allowed manufacturers a 67-to-1 return on taxpayer investments and has saved Oklahoma manufacturers more than $15 million since its inception. Those numbers are only continuing to grow, Krishnamurthy said.

“This program is 27 years old and still has a lot of impact to this day in how we provide engineering services to the state,” said Mari Chinn, OSU BAE department head.

The program has five key metrics: increase

sales, retain sales, increase jobs, retain jobs and save on costs. Krishnamurthy said the OMA is a key player in ensuring these metrics are met within the industry partners.

The OMA employs eight manufacturing extension agents who work with OSU Extension educators across the state to help manufacturers identify technology assistance-related opportunities, Krishnamurthy said.

The applications engineers program also influences the Oklahoma manufacturing industry through BAE’s senior design projects.

The applications engineers work with senior biosystems engineering students at OSU to develop and implement new technologies that assist Oklahoma manufacturers, Chinn said, and these working relationships can help lead to job opportunities for our OSU graduates.

“Our department bridges between the College of Engineering, Architecture and Technology and OSU Agriculture, so we are able to connect all the necessary expertise to provide to the state,” Chinn said.

In the past, the applications engineers were limited to only showcasing mobile technologies, but with the new “brick and mortar” lab in Catoosa, Oklahoma, manufacturers can see some technology that is not as portable, said Ben Alexander Sr., applications engineer.

Alexander, alongside application engineers Andrew Huffman, work with OMA staff and BAE faculty and are able to fulfill the applications engineering mission from the state-of-the-art technology lab, he added.

In the lab, Oklahoma manufacturers can experiment with a variety of cutting-edge technologies, including cobots, 3D printers and more.

“The lab is a new demonstration facility to highlight robotics and automation,” Chinn said.

“It’s an opportunity for learning, knowledge

gaining and technology transfer.”

The Catoosa lab, funded by the OMA, is modeled after a full-facility system, showing how cobots can be used to create a product, test its integrity, package it and prepare the packaged products for shipping.

In addition to this circuit, a second area in the lab allows experimentation with heavy-duty 3D printers and high-tech interactive whiteboards.

“The lab is designed to show manufacturers what and how they could use cobots for in their businesses,” Alexander said.

The lab opened in March 2024 and allows manufacturers, politicians, educators, and others to experience technology designed by OSU’s applications engineers.

“We make sure that whatever we do we engage in sustainability,” Krishnamurthy said.

“If no one on staff can operate the equipment we provide, it isn’t a sustainable solution.

“Manufacturers need to have some engineers and trained technical staff on their team for successful adoption of technology.”

As the program continues to grow, the applications engineers hope to become more involved with undergraduate student workers, Krishnamurthy said.

“Applications engineers have done many different projects from helping optimize processes to adjusting facility layouts,” Chinn said.

“Sometimes they are heavily involved in devising new approaches and technologies that can be adopted by industry to make businesses operate better.

“It is inspiring to witness the impact this program has had on the state and recognize its beginnings as a vision and seed that blossomed from the agricultural engineering program,” Chinn added.

Skilled Communicators In early September, two students were selected as recipients of the Presentation Excellence Award at the 2024 American Society of Agricultural and Biological Engineers annual conference.

Kasra Khodkar, a Ph.D. student in the School of Biosystems and Agricultural Engineering, working with Dr. Ali Mirchi as a graduate research assistant and Nathaniel Bolujoko, a Ph.D. student studying environmental science who works with Dr. Kiranmayi Mangalgiri as a graduate research assistant in BAE, received the honor over the summer.

Khodkar is from Tabriz, East Azerbaijan, Iran, with a research focus on water resources management and hydrology.

Nathaniel Bolujoko is from Kwara State, Nigeria, and focuses on understanding the fate of contaminants of emerging concerns such as antibiotics during the process of recovering phosphorus from swine wastewater that becomes a material known as struvite.

While they weren’t both working directly together on research, Khodkar and Bolujoko both worked together within the Biosystems and Agricultural Engineering Graduate Student Association. Khodkar was vice president while Bolujoko was the secretary, and Khodkar served as president when Bolujoko was the vice-president. Bolujoko is now president of the organization starting this semester.

Bolujoko said the two of them have developed a friendship that extends beyond their time on campus.

“It’s been amazing actually because we can just discuss anything happening,” Bolujoko said. “Not just in the department but outside of the department as well. It’s not just professional. It’s a personal relationship, so it’s been good working with Kasra.”

Khodkar said he has also made a good friend in the time he has known Bolujoko.

“I have enjoyed my time working with him.

He has been a very good team member,” Khodkar said.

students presented posters of their research and were awarded the Presentation Excellence Award.

“In this presentation, I discussed that antibiotic residues in swine wastewater can co-recover with phosphorus product (struvite) recovered from swine wastewater,” Bolujoko said. “In addition, I discussed various factors that contribute to this. The contamination of struvite with antibiotics poses a significant threat to both humans and the environment, as this could lead to the spread of antibiotic resistance.”

Khodkar’s research focused on watershed scale modeling of water salinity in the Upper Red River Basin.

“Reoccurring droughts and increasing demand for water draws attention of water resources experts to assess the potential utility of the available saline water resources, particularly for saline water irrigation of salt tolerant crops,” Khodkar said. “However, using saline water resources can interrupt the salinity balance in watersheds and basins, and result in adverse agroecosystems impacts. Thus, modeling and simulation of any saline water usage is required before making any suggestions.”

Khodkar said the importance of studying water salinity is integral because of the global necessity of having more usable water.

“There are many regions around the world, facing water salinity problems, saltwater/seawater intrusion, and freshwater scarcity, which 21

the modeling framework we are developing can be used for informing the water resources managers,” Khodkar said.

Bolujoko said studying antibiotic residues in water resources can shed light on their impact on the environment.

“My research is important in understanding the various ways by which antibiotic residues are reintroduced into the environment, the potential impacts on humans and the environment, and developing ways to minimize the spread of antibiotics, ensuring the protection of humans and the environment,” Bolujoko said.

The importance of pursuing Ph.D.s While Khodkar was an undergraduate student he took a hydrology course where he learned of water-related issues around the world. This led him to pursue water-related research while working to get his master’s degree and Ph.D. “When I came across the opportunity of doing water research at Biosystems and Agricultural Engineering department of OSU, I did not hesitate to take it,” Khodkar said. “I was really looking forward for potential professional development and research opportunities at OSU as a land-grant institution, and I can say I found more than what I expected.”

Bolujoko was inspired by his desire to attend graduate school. He has always been interested in research, especially relating to the environment and human health. He also wants to inspire members of his family by achieving his goal of obtaining his Ph.D. “I have a strong desire to earn a Ph.D. and become the first person in my family to achieve this academic distinction, inspiring future generations,” he said.

22

Within CEAT, both students have been able to find guidance from a wide variety of mentors.

These mentors have provided a well-rounded layer of support for both students.

Bolujoko said Dr. Kiranmayi Mangalgiri has been a one of his greatest advisors and that he appreciates how she is open to new ideas.

“In the past few years that I’ve worked with her, I have experienced growth, not only in my personal life, but professionally as well,” Bolujoko said. “I think that what I’ve been able to do and the awards on campus I have been able to win are because of her contributions. Working with her has been an amazing part of my experience.”

Khodkar said he has received tremendous support, not only in research and coursework, but help with his communication skills, expanding his professional network, helping him acclimate to the academic environment in the U.S. and helping him through some tough times.

“I am glad I took this opportunity to be a member of the Orange Family,” Khodkar said.

“Awards, goals, and even the degree I am seeking are great achievements. However, I think the process, the path we are going through is more educating and in my opinion is more valuable.”

Undergraduate academic program coordinator Dakota Keith has had a busy year attending state science fairs, managing prospective student site visits, and student organization events on behalf of the department in order to recruit the next BE and AST graduates. In addition to meeting future students, often supported by various faculty members, Dakota is also leaning in on the other critical component of recruitment - continued retention. Between learning about mentorship, developing relationships with our student body, and fostering continued connections with alumni, Dakota has been dedicated to supporting our students at all stages of their collegiate journey.
