Dear Colleagues,

Guillermo Aguilar Chair, UCR Mechanical Engineering

The past few years have been characterized by prominent growth and accomplishments for the mechanical engineering department. The hiring of 11 new ladder-rank and one teaching faculty since 2014, has transformed us into a mid-size department and has helped us build upon our department’s core research areas. The high quality of our faculty continues to stand out way above the norm of even the most prestigious departments. Collectively, current ME faculty have been honored with 16 young investigator awards from the most prestigious federal agencies: 10 NSF, 1 DoE, 2 ARO, 1 DARPA, 1 NIH and 1 ONR, with some of them receiving more than one. This represents an impressive average of 62% of young investigator awards attained by our faculty. Also, many of our senior faculty are highly decorated. Collectively, we have 10 Fellows of prestigious professional national and international societies, such as ASME, AAAS, AIAA, ASM, and others.

We welcomed four outstanding new faculty members this year, including Christopher S. Lynch, the new dean of the Marlan and Rosemary Bourns College of Engineering (BCOE). He is a Fellow of ASME, SPIE, ASEE and ACERS, the past director of the No. 1 ranked online master’s engineering program at the University of California, Los Angeles, and served as past chair of UCLA’s Department of Mechanical and Aerospace Engineering.

Three accomplished assistant professors also joined our team and include a Fulbright Scholar, an AAC&U K. Patricia Cross Future Leader of Higher Education awardee, and a researcher from Princeton University’s Carbon Mitigation Initiative.

The recognition to our work is also evidenced by the support of major granting organizations. Just last year, our faculty received grants from numerous agencies, such as DARPA, NASA, the Bill and Melinda Gates Foundation, DOE, DoD and NSF. This has sparked an increase in interdisciplinary work resulting in connections with other UCR schools, such as

the School of Medicine and the College of Natural and Agricultural Sciences, as well as strengthened our partnerships with universities in Mexico.

In addition to helping aid our research efforts, grants are also supporting our graduate students. This year, the Department of Mechanical Engineering was one of five Graduate Assistance in Areas of National Need (GAANN) grants awarded to BCOE, allocating $895,000 over the next three years to support six mechanical engineering graduate students per year.

Our undergraduate students are excelling as well.

The Society of Automotive Engineers (SAE), the student professional organization most closely tied to our undergraduate students, had a great showing at the 2018 Formula SAE competition in Lincoln, Nebraska, where students are tasked with developing and constructing a single-seat racecar evaluated on design, construction, performance and cost.

Highlander Racing’s internal combustion vehicle flew past inspections and, following an engine seize, the team pulled off an entire engine swap in four hours to complete the competition. They have now switched gears to an electric model racecar, one of the first of its kind in the country, and are set to compete later this year.

It’s been an exciting time for our department and we hope you join us as we work to develop solutions to some of the world’s greatest engineering challenges.

Regards,

Guillermo Aguilar Chair, UCR Mechanical Engineering

A RACECAR OF THE FUTURE

The machine shop serves as home base for the Society of Automotive Engineers at UC Riverside. Officially called Highlander Racing, the student professional organization brings together students from all five engineering disciplines as well as students from the School of Business and College of Humanities, Arts, and Social Sciences.

Their latest project, an electric racecar, is expected to be the first in the nation to successfully implement the powerful combination of a liquid cooled battery pack with an all-wheel drive system that brings a competitive advantage to the Electric Car Competition.
