A Message from Dr. Chinn

Welcome 2023!

We are excited to be able to resume providing the “BAE Update” to highlight some of the activities and achievements of our Oklahoma State University BAE family in 2022! We had a lot to be proud of and celebrate over the past year.

We successfully earned continued ABET accreditation for our Biosystems Engineering program after our review and evaluation visit in Fall 2021 and continue to make strides in our continuous improvement. In this communication you will learn more about our new Agricultural Systems Technology (AST) degree which was initiated in Fall 2021. Our AST enrollment has grown to 19 students in the last year! We look forward to the development of the program and accomplishments of our AST students.

We have been fortunate to recruit two new talented faculty members to advance the department’s teaching, research, and Extension missions, and are in the process of hiring two additional tenuretrack faculty in irrigation and water management. Dr. Randy Taylor has also decided to return to us at the faculty ranks from his role as the Extension Assistant Director and State Program Leader for Agriculture and Natural Resources to support our machine systems research and Extension activities.

I am impressed with the scholarship, contributions, service, connectedness, and impact of our faculty, staff, students, and alumni. Several have been awarded our highest university and college honors and others are continuing to excel in their work and bring recognition to the department and university. Pokes in and connected to the department are really outstanding. Please enjoy reading about their experiences and pursuits in this communication.

As many of you know, the Division of Agriculture and Natural Resources is constructing a new building, New Frontiers Agricultural Hall, to house classrooms, administrative, faculty, staff and graduate student offices, and laboratories. New Frontiers is on schedule to open its doors in Summer 2024. In alignment with these new facilities, we have embarked on making major renovations to the welding lab and the south side of the Biosystems and Agricultural Engineering Laboratory. We anticipate being able to invite you in to look at our new space very soon!

The department appreciates the dedication of our advisory committee for their useful input and feedback in making new connections, advising on workforce training and industry demands, recruitment and retention efforts, and programmatic directions. We are extremely grateful for our alumni and friends that are generous with their time and monetary donations that enhance the quality of our department and elevate the value we are able to offer our students, collaborators, and stakeholders. The engagement of our alumni and friends is wonderful and I welcome future opportunities to involve more of them in our work and play.

As we hold on to special moments and memories of life and people from the last year, I wish you all good health, joyful adventures, laughter, and true happiness in the new year!

Sincerely,

A Site for New Opportunities

If you daydream of fixing tractors, managing your family farm, or enjoy working with your hands, Oklahoma State University’s new agricultural systems technology major may be a good fit for you.

Students looking for a hands-on degree program now have a new opportunity with the AST major in the Ferguson College of Agriculture.

Nestled in the OSU Department of Biosystems and Agricultural Engineering, the AST undergraduate degree program offers a uniquely different learning experience compared to other majors, said Paul Weckler, BAE professor.

“It’s a very practical, hands-on, industryoriented degree that is not focused on a specific technical discipline,” Weckler said. “The AST program looks at all the aspects of the technology needed in different areas.”

Because of this, graduates of the AST degree program can work in the industry as food scientists, machinery technicians, grain elevator operators, water treatment plant operators or several other management and hands-on positions, Weckler said.

The goal of the AST degree program is to fill “the niche between an engineer and a subject matter specialist,” Weckler said.

Although the new AST program began in Fall 2021, the program is not the first of its kind to be offered through the BAE department.

Prior to 1990, the department offered a mechanized agriculture degree program, according to the OSU Office of the Registrar Catalog Archives.

However, with the oil crisis leading to a poor economy, budget cuts meant eliminating this program, Weckler said. Talks of adding a technology degree to the BAE department have occurred for years, he added.

We’ve had lots of feedback from our industry advisory board,” said John Long, BAE associate professor and AST academic adviser. “One of the things they kept telling us was there’s this big need for technology students and not necessarily engineers.”

The suggestions from the advisory board — coupled with similar thriving degree programs offered at Texas A&M University, Kansas State University and the University of Nebraska meant adding this degree

program became more important than ever, Long said.

“We felt like we were missing out on a major that there’s definitely a need for,” Long said.

Long chaired the BAE department’s committee to start the process of implementing this new degree program. This included creating the course curriculum, demonstrating a need for a new program, and submitting proposals to the college and OSU/ A&M Board of Regents, Long said.

During the first semester of the major, five students enrolled in the major and took core curriculum courses in agricultural water management, surveying and agricultural electrification.

As a part of the core curriculum, AST students also take business and economics classes, Long said.

“One of the things that sets the AST degree apart from the other technology majors at other universities is we actually have a business portion required,” Long said. “It gives students the ability to go into a situation where they could work as a manager for other people in a technology-related field.”

In addition to the core curriculum, students pursuing the AST degree choose their own path for 21 hours on their degree sheet, depending upon the direction they would like to go after college, Long said.

This offers more flexibility to students and their interests, making it unique among similar programs at other universities, Weckler said.

Across the U.S., other agricultural technology degree programs are focused on more specific disciplines such as machinery and tractors, which offers less flexibility, he added.

With my agricultural systems technology major, I will also be earning an agribusiness minor,” Smith said. “You can configure this degree to just about any way.”

A different path to take with the AST program is a plant and soil sciences focus, said Alan Davis, AST junior. Davis said he chose this path because he enjoys his job at Oklahoma Foundation Seed and knows this program fits well with his interests and future job opportunities.

Students also can take a machinery-focused course load within the new AST major, said Michael Bird, AST junior.

“Agricultural systems technology is really cool because it is such a niche major,” Bird said. “What I have chosen to do is a very mechanical and machine systems-based major, anything that can be useful in a professional scenario when it comes to working on tractors or in a design and/or prototyping position.”

Students in the program agree they are being prepared for the real world in a handson career path, but the faculty are what makes this program so special, Smith said.

“They want you to be there, be engaged, and ask questions,” Davis said. “They are not there just to present. They are there for you to actually learn in their classes.”

Since the major is new, the classes are small and the professors take interest in each student, making a point to interact one-onone, Smith said.

“The community and the culture in the department really makes the major worth it,” Bird said.

With stellar faculty who genuinely care, applicable curriculum and hands-on learning, the new AST degree program is a good fit for students seeking something a little different in college, Bird said.

“Everything in this major is applicable to life,” Smith said. “If you learn something, there is a reason you are learning it and you can directly see what it is going to be used for and what it is going to be.”

Michael Bird uses hands-on learning experiences to prepare him for his career.

“That’s something I really appreciate about AST. For students who love being hands on and working with machinery, I think this would be a great fit.”

New AST Student Spotlights

Why did you choose this major?

“Choosing to major in AST was an easy decision for me. I was looking for a major that was unique, had a lot of options post-graduation and featured a broad education in numerous subject areas” said Bean. Bean is a transfer student from Modesto Junior College in California who has a passion for the mechanical and technological aspects of the agriculture industry.

Kaitlin Bean, Modesto, CA

What is a typical school week like?

“For me, every day is different which is one of the perks of the major. One day could be lots of classes while another day may be mostly open with a lab or two, but either way it keeps it interesting” Kellen Ross said. Ross is a senior who was one of the first four transfer students into AST. Kellen Ross Smith, Columbia, MO

Do you have advice for any students considering AST?

Bryce Coon, a junior who transferred into AST, is enthusiastic about the major. “AST is such a great area to study. I came from a very small town and wasn’t sure what I was getting myself into. But after I found AST, I can relate everything I have learned over the years on the family farm to my course work. If you’re a small-town farm kid, I would highly recommend giving AST a shot!”

Hall of Fame Inductee, Lohmann Medal Recipient Mr. Lieu R. Smith 2022

Lieu R. Smith , P.E. grew up on a wheat farm 10 miles away from Okeene, Oklahoma after moving from Michigan City, Indiana, during the Great Depression. All eight grades were taught in the same classroom with one teacher for much of Smith’s grade school experience. As he entered high school, agriculture was one of the basic classes he was required to take.

Growing up in a rural area inspired him to major in agricultural engineering with an emphasis on soil and water conservation. He graduated from OSU with his bachelor’s degree in agricultural engineering in 1954 and with his master’s degree in structural engineering in 1957. Smith also spent two years on active duty with the U.S. Army Corps of Engineers.

“My undergraduate time at OSU was a major time of adjustment from a small rural school background to a major university

setting,” Smith said. “It permitted me to expand my horizons academically and socially, as well as, mature in my decision making-processes.

My time at OSU, followed by going into the U.S. Army Corps of Engineers as a Commissioned Officer formed a core structure of who I was and the lifestyle principles that I stood for.”

Smith spent the majority of his engineering career working with Sverdrup Corporation in St. Louis, Missouri, where he eventually rose to become the rank of corporate VicePresident of Advanced Technology. The corporation is now a part of Jacob’s Solutions Engineering Company.

His engineering career started in the early 1960s working with Sverdrup for the Saturn V Program, which resulted in the sending of a man to the moon.

This was only one of the well-recognized projects Smith got the opportunity to be a part of. He got to work on, manage and host projects like test facilities for 300 mph tracked air cushion research vehicle, a 400mile oil pipeline and marine terminal in the country of Algeria, liquid and solid-rocket engine test stands for the Space Shuttle and a $20 million Space Shuttle Launch Pad Complex at Vandenberg, California, Air Force Base.

“The Space Shuttle Launch Pad Complex is the project that I am most proud of,” Smith said. “Because it was Air Force sponsored instead of NASA, with different missions, different payloads and operational requirements, it also presented new, as well as, constantly changing requirements. We had a fixed price contract and schedule with the Air Force so there was a constant flow of contract changes along with design requirement changes.”

Smith’s work as the project manager for the Space Shuttle Launch Pad Complex received numerous awards. On March 5, 1984, the project was featured in Time Magazine and the launch pad complex was described as the “most sophisticated military complex ever built.” Smith’s project earned Sverdrup the 1985 Grand Conceptor Award for Excellence in Engineering by the American Consulting Engineers Council and the complex was recognized as one of ten outstanding engineering achievements from the National Society of Professional Engineers.

In 1993, Smith retired to devote his time to working for his church as a selfsustaining ordained minister. He pastored the Berryville, Arkansas Community of Christ for eight years and was awarded the

status of “Pastor Emeritus” upon his retirement at the end of 2003. He continued to serve as a hospital chaplain, as well as, on a number of committees and boards at Mercy Hospital.

“I have always been mindful that I am in reality an Oklahoma farm boy who grew up on a very marginal farm during the dust bowl days,”Smith said. “Through the encouragement and help from a lot of very good people, I became very successful in my profession, thus it is my intent to give back to society by helping others.”

BOTTOM: Smith managed the design and construction of the Vandenberg Space Shuttle Launch Complex in California.

Smith has practiced helping others through many different professional and community activities.

He has been actively involved in the “Loaves and Fishes Food Bank of the Ozarks” by designing and funding construction of a new facility for the storage and distribution of food to the needy of Carroll County, Arkansas. He has also endowed a scholarship fund for female Native Americans to become doctors of osteopathic medicine through the OSU Center for Health Sciences.

Continuing to learn about new concepts and figuring out your strengths are two pieces of advice Smith recommends to all students in CEAT.

“Don’t be afraid to venture into new avenues of work that you are not familiar with,” Smith said. “Rockets and Space Ships were not even part of our vocabulary when I was in school. Secondly, discover what your best talents are and work to maximize them in your work. I found that mine was being able to organize projects and bring them to a successful conclusion.”

Breaking Barriers

Sometimes, the biggest lessons in life are taught during a serendipitous moment. Just ask Mary Elizabeth Mach, P.E. Mach, an Oklahoma State University (OSU) Biosystems Engineering graduate from the class of 2006, is the perfect example of how the lesson of advocating for oneself makes all the difference.

To tell Mach’s story fully, we must go back to November 2005. Mach, a senior at Oklahoma State University, attended the fall career fair. It was there that she saw a table for the engineering firm Garver and decided to speak to the representative there. As she approached to hand over her resume, the hiring representative told her that the firm traditionally hired Civil Engineers, not Biosystems Engineers and there likely wouldn’t be a role that fit her skillset at the firm. This would be a point in Mach’s life where the simple, but often difficult, task of advocating for herself would prove paramount.

At this point, the easy route for Mach would have been to accept what the Garver hiring team said and walk away. However, that is not what happened.

Undeterred, Mach advocated for herself and was able to convince the recruiting representative to accept her resume and pass it to the hiring committee. From then on, the rest is history. As one could imagine, the firm now hires many Biosystems Engineers – several of those recruited by Mach.

Advocating for herself is now a skill more important than ever for Mach, who was recently named the new Water Director of the Western Region at Garver, the first woman and youngest person to ever hold this role. This comes on the heels of her being named to The Journal Records’ “Achievers Under 40” list in 2021.

When asked about what this new promotion means to her, “I am proud of my new role. It demonstrates how the industry as a whole is evolving. There are more women within

my firm now that we can pull from for positions. I love that the pool of women involved in STEM and the industry is growing!” Mach said.

So, what is Mach’s favorite part of working at Garver? The people.

“There is not another team that I would rather be working for” Mach said. In her position, Mach gets to establish and maintain client relationships at Garver, which is something that she does not take lightly.

Speaking with Mach, it is obvious how kindly she looks back on her time in Biosystems and Agricultural Engineering (BAE) at OSU. Mach spoke about how the culture in BAE impacted the corporate culture that she tries to establish at Garver. “Jana Moore influenced me heavily in that she taught me that everybody’s name is worth knowing. That everyone deserves to be respected for their hard work, no matter their level in an organization. Not being too big for your britches is something that I took home with me. She powerfully influenced how I have interacted with people in my day-to-day professional life.”

Cole Niblett, Oklahoma Water Team Leader at Garver and a 2016 OSU Biosystems Engineering graduate, further reiterates just how much people mean to Mary Elizabeth. “One lesson I have learned from her would be how to truly and effectively listen to people. Such a simple concept, but I have seen projects go so much more smoothly and countless examples of reaping benefits in business because we actually listened closely to what people were trying to tell us. Beyond dividends from the business perspective side, it’s also a lesson that has improved both my professional/personal relationships and networking.”

One of her favorite memories is throughout her senior year, Mach and other students would have monthly potluck-style dinners. The tight-knit family atmosphere that BAE has is something that Mach still looks back fondly on to this day.

When asked what advice she would give to any current BAE students, Mach is clear. “Advocate for yourself. If I didn’t advocate for my resume at the career fair years ago, I would not be here at Garver - the best place to work!”

We are always interested in keeping in touch with our alumni and friends. Please feel free to share some of the great things happening in your lives with us!

Retired Engineer Invests in a New Generation of Students

Bill Petermann, a 1960 OSU graduate with a degree in agricultural engineering, was surprised this past spring when a group of OSU students from the student chapter of the American Society of Agricultural and Biological Engineers arrived on his front lawn.

The small army of students got to work cleaning gutters, raking leaves, mowing, weeding the garden, clearing honeysuckle off the fence, organizing equipment and more. The students were taking part in Into the Streets, a day when OSU student organizations assist Stillwater community members with household or yard chores.

Petermann was elated to find out the student group sent to work on his projects were pursuing a career path similar to the one he enjoyed for 38 years as an agricultural engineer working primarily on watershed and irrigation projects. He spent nearly the entirety of his career at the USDA-Natural Resources Conservation Service, serving Oklahoma farmers and ranchers.

The longer the students were there, the more Petermann got to know them.

“It reminded me of when I was in school,” Petermann said. “They just seemed like a family.”

Collin Bellmer, ASABE president and a student in the OSU Department of Biosystems and Agricultural Engineering, was just as surprised as everyone else when he learned about Petermann’s background.

“It was a crazy coincidence,” Bellmer said. “My first thought was, ‘What are the odds of this happening?’”

Mattie Wood, ASABE historian and biosystems engineering student, said that while everyone had been excited to help Petermann out, the fact that he was a fellow engineer motivated the volunteers even further.

“We recognized we were giving back to the engineers that came before us, Wood said. “It was fulfilling to do something tangible to help him.”Petermann felt a camaraderie with the group.

I was so surprised when I found out they were in an organization I had been in and enjoyed (as a student),” Petermann said. “It brought back so many memories.”

Memories like trips to the dance hall on the fourth floor of the Student Union where students could socialize; having a soda and

dancing to the latest songs from Elvis Presley, Frank Sinatra and Johnny Cash; carpooling to campus every day with four of his buddies; and working on the School of Engineering’s publication.

It also reminded him of his financial need during his time at OSU.

Petermann was the first in his family to attend college in 1955. Although his parents didn’t have traditional opportunities for education, they understood the importance of a quality education and encouraged Petermann to pursue a degree.

But funding was a problem.

“My vocational agriculture teacher gave me a scholarship application to fill out from Sears and Roebuck,” Petermann said. “They awarded it to me.”

The scholarship paid his full tuition his freshman year, and after his first year in ag engineering, he “caught the bug.”

Engineering A Legacy

Once the grass was cut, the weeds were pulled and the gutters were cleared, Petermann wrote thank you notes to each of the volunteers to express his gratitude.

“A thank you seems so little after you have given me so much,” Petermann wrote in a letter to Wood following the event.

A year later, the first Bill and Ladonna Petermann Endowed Scholarship was awarded at the Biosystems and Agricultural Engineering Department Scholarship Banquet in March 2022.

Petermann said he had considered initiating a scholarship for the department for some time, but Into the Streets was the ultimate catalyst for him. He recognized the importance of quality engineers in the future of the agricultural industry, saying he was excited by the innovations he’s seen since he left the field. Petermann also said he wanted to help alleviate financial pressures for students so they can enjoy their time in college without the stress of a tuition bill looming.

“I wanted to encourage someone to be involved in campus activities while they’re in school in hopes they stay involved,” Petermann said.

Taos McIntyre, a junior biosystems engineering student, was the first to receive the Bill and Ladonna Petermann Endowed

Scholarship.

“I think it’s really interesting how something like Into the Streets can result in such a deep connection between current students and alumni,” McIntyre said.

Petermann and McIntyre got to meet each other at the banquet.

“I could tell the banquet was very emotional for the Petermann family because there were a lot of important reasons behind the scholarship and why they decided to make their donation,” McIntyre said. “Seeing that meaning and seeing how important it was to them made me feel very fortunate that I got to meet them.”

Uniquely Situated

Growing up in urban Oakland, California, Mari Chinn never imagined a future intertwined with agriculture.

Before receiving her Master of Science and Doctor of Philosophy degrees in biosystems engineering, her perspectives of farming primarily included highway views, Chinn said.

Now, Chinn heads the OSU Department of Biosystems and Agricultural Engineering within the Ferguson College of Agriculture and the College of Engineering, Architecture and Technology. She also serves as the interim director of the Biobased Products and Energy Center.

Since starting in January 2021, Chinn has used her specialized research knowledge along with her personal background to lead a complex department, she said.

“I would be on golf courses with nut trees, smell the cow pastures and see the flooded areas going from Oakland to Tahoe as part of my unwitting knowledge of agriculture,” Chinn said. “I liked biology and math, so I did undergraduate research in the Department of Biological and Agricultural Engineering at the

University of California-Davis.

“I received a National Science Foundation Graduate Research Fellowship. It allowed me to branch out into different spaces.”

As a master’s student and later a doctoral student at the University of Kentucky, she gained a deeper understanding for agriculture through her microbial research pursuits and the sheer proximity of farms, she said. After completing her degrees, she pursued a professorship at North Carolina State University, where she stayed for 18 years.

“Then, someone from Oklahoma State called,” Chinn said. “I saw the potential to have a leadership role outside of my own research and teaching.”

Chinn has a widespread impact across BAE by assisting faculty and graduate students with research and grant applications, said Randy Raper, OSU Ag Research assistant director.

The students and faculty alike respect her,” Raper said. “She is engaging and has been creating a common vision for people to work toward.”

He said Chinn’s vision includes building up

the agricultural systems technology program, a new major housed within BAE. Although the program was in development before her arrival, Chinn spent time asking questions to solve problems before they arose, Raper said.

“What is really engaging about Dr. Chinn is she didn’t come from a rural background, but she recognized the part of agriculture she could identify with,” Raper said. “She’s been able to make an impact and be a role model for other people who are similar.”

With academic experience in California, Kentucky and North Carolina, Chinn brings a rich background to her position at OSU, said Ron Elliott, BAE department head emeritus. As the first woman and first person of color to lead the department, she serves as an outstanding role model, he added.

Danielle Bellmer, BAE professor, said, 20 years ago she was the first female faculty member in BAE. “When I started, there were only four female faculty members in the whole College of Engineering, Architecture and Technology,” Bellmer said. “Today in BAE, it is close to 50% female in both faculty and students.”

A lot of people in leadership put up walls or lose their personality, but Chinn does not, Bellmer said. Chinn’s leadership style is marked by transparency, honesty and community-building, she said.

“It takes time to break through stereotypes and allow time for people to see role models,” Bellmer said. “Dr. Chinn is certainly one for a lot of people these days.”

Another hallmark of Chinn is being a good listener, Bellmer said. Making sure to get input from everyone, especially those who typically might not speak up, allows for different perspectives to be heard, Bellmer added.

“I do recognize that even though it’s never my intent to be a model for anybody, it does help for many young women and young women minorities to see if I’m in this position, they can be, too,” Chinn said.

As someone who has worked in the department through multiple department heads, Jana Moore, BAE undergraduate academic program coordinator, remarked Chinn has a unique ability to connect with others.

“Dr. Chinn just has an energy that makes you excited to work for and alongside her,” Moore said. “When you feel seen and are working toward a common goal, it is a very comfortable environment.”

Chinn’s ability to put an emphasis on camaraderie for faculty and staff has been well received, Moore said.

“Watching her interact with longtime donors her first year was almost baffling

because Chinn did it so well,” Moore said. “She shows you do not need to be an alumnus yourself to connect with the Ferguson family, and she showed the department’s deep appreciation with excellence.

As someone not from a rural background herself, Moore said Chinn represents an accurate swath of students who are not rural either.

“When I meet with prospective students, they sometimes ask if they will fit in without a commercial agriculture background,” Moore said. “It is great to be able to let them know the department head grew up in the city and represents agriculture and engineering so well.”

Growing up a golfer, basketball player and involved community member, Chinn said she loved where and how she grew up.

“I don’t deny any one aspect of my identity and neither does the department,” Chinn said. “What I can offer with my cultural

experiences and living as a mixed-race person is being open to everyone and anyone.”

The department is an integration of agriculture, life sciences and engineering, Chinn said.

“The faculty, staff and students in BAE work together to make a difference in people’s lives, she added.

“Dr. Chinn really has brought a new life to the department,” Moore said. “She is the kind of person you want to work for your entire life.”

Chinn’s care for people, work-life balance, strong focus, impressive intellect, and passion for biosystems and agricultural engineering are just a few of her characteristics that inspire those around her, Elliott said.

“Why do I do what I do?” Chinn asked. “I always want to try to add value to people’s lives. That’s the one reason I do what I do.”

The BAE-GSA at Oklahoma State University supports departmental graduate students in professional development, building community, and identifying solutions for and offering a voice to unique challenges that we face in pursuing our graduate degrees. We presented our activities and officers to our professional society members during the annual OK section meeting of the American Society of Agricultural and Biological Engineers (ASABE) in April.

We had a nice cohort of graduate students who attended the Annual International Meeting of the American Society of Agricultural and Biological Engineers (ASABE) in Houston, TX this past July. In preparation for the professional meeting, we hosted an all-day mini-conference for student participants to practice their presentations and get constructive feedback from faculty and their peers. We enhanced our oral communication skills, learned more about the work taking place in the department, as well as eating very well that day!

To jump-start the Fall semester and get to know the new faces better, BAE graduate students and post-doctoral research fellows enjoyed a bonding dinner at Hideaway Pizza. For Halloween, GSA held a department-wide party in the graduate student office. The party included a pumpkin carving contest, spin the wheel and a movie night. We are looking forward to Spring semester and creating new and exciting activities with our new officers initiated for 2022-2023: Vice President: Kasra Khodkar; Treasurer: Navdeep Saasan; Secretary: Nathaniel Bolujoko; GPSGA Officer: Chijioke Leonard Nkwocha and Dabira Ogunbiyi

Cowboy Motorsports

Director: Seth Stone Advisor: John Long

The Cowboy Motorsports team designs, fabricates, and promotes a unique tractor for the annual International 1/4 scale (IQS) tractor competition sponsored by the American Society of Agricultural and Biological Engineers (ASABE). With members from all majors, the team comes together to develop their skills in design, manufacturing, interdisciplinary teamwork, marketing, accounting, written and oral communication. This real-world experience continues to challenge members in ways that are not easily achieved in the classroom. Beyond preparation for the competition, in 2022 Cowboy Motorsports participated in community service activities with Into-the-Streets, executed the annual lawnmower clinic, and was active in Homecoming week making contributions to the Sign Competition, the Harvest Carnival, offering the pulled pork sandwich fundraiser at WalkAround and running 4 operable 1/4 scale tractors in the Sea of Orange Parade! In addition, the team consistently assists the department with recruitment activities and provided barbeque pulled pork in support of BAE’s first United Way fundraiser! Currently, Cowboy Motorsports is working on the design for their 2023 tractor.

In addition, we participated in the window painting competition and painted images of the four different Biosystem Engineering major options (Bioprocessing and Food Processing, Machine Systems and Agricultural Engineering, Pre-Med and Enviromental and Natural Resources, as well as our new major, Agricultural Systems Technology. At the end of the year, Alpha Epsilon joined in the Ferguson Christmas Tree decorating competition. Our tree’s theme was “Keys to Success” with the tree covered in keys with the different words that represent a definition of success. This Spring Semester, Alpha Epsilon will resume hosting the Biosystems Olympics.

ASABE

President: Gavin McCullough

Advisors: Jessie Mao and Kevin Moore

The ASABE student club kicked the 2022-2023 school year off with a back-to-school picnic at Couch Park. This allowed new ASABE members to interact with their peers and others in the department. ASABE held biweekly meetings hosting speakers from NRC, Kimley-Horn, U.S. Army Corps of Engineers and the BAE senior class where students shared their career and professional experiences. Outside of professional development and networking, ASABE members participated in civic and social activities throughout the semester, including Harvest Carnival, Homecoming Sign Competition and Window Painting, Into the Streets, and Dean’s Volleyball. In addition, ASABE sold BAE departmental apparel as a fundraiser, where pokes could purchase hats, polos, and pullovers through an online store. We also helped Cowboy Motorsports sell pulled-pork sandwiches at OSU’s Homecoming Walkaround. In the coming months, ASABE members are gearing up to host the annual Student Awards Banquet.
