Celebrating Black Alumni Recognizing the achievements of black scientists and engineers from the department of mechanical and aerospace engineering

Cullen Buie  (BS Mechanical Engineering ‘03)

Cullen Buie is dedicated to furthering the field of mechanical engineering in his appointment as associate professor at Massachusetts Institute of Technology. He is also designated as the Esther and Harold E. Edgerton Career Development Professor.

Dr. Buie has a long resume of publications, conference proceedings, conference and invited presentations and intellectual property. These make him a standout among the department’s young alumni. He has received numerous awards and honors, including the DARPA Young Faculty Award, DuPont Young Professor Award, NSF CAREER Award and Presidential Early Career Award. Additional leadership and service experience features his extensive work supporting conference organization and beyond.

The impressive record of Cullen’s contributions to the field centers on his research interests: microfluidic tools for genetic transformation in synthetic biology, dynamic interactions between fluids and porous media, and low-cost energy storage systems.

Graduating with the distinction of magna cum laude, Buie earned his bachelor degree in mechanical engineering from Ohio State in 2003. He went on to earn his master degree and PhD from Stanford University.

Sarah Bentil  (PhD Mechanical Engineering ‘13)

Dr. Sarah Bentil began her PhD program at the Department of Mechanical and Aerospace Engineering in 2008 as a fellowship student and began working on a project to improve the biocompatibility of neural electrode systems using hydrogels. With her faculty advisor, Rebecca Dupaix, she conducted rheological experiments on porcine brain tissue samples extracted from each hemisphere and different locations within the brain.

Bentil is now a professor at Iowa State and is director of a new lab, The Bentil Group.  The group’s mission is to develop innovative methods to test soft biological tissue and biomaterials to identify, treat and/or diagnose diseases in soft tissue. Her students are developing and employing noninvasive experimental techniques to characterize the behavior of the brain and other soft materials and conducting computational studies to gain insight into how they relate to various biomedical problems.

Onome Scott-Emuakpor

Onome Scott-Emuakpor (MS Mechanical Engineering ‘04, PhD Mechanical Engineering ’07)

Dr. Onome Scott-Emuakpor is dedicated to furthering the fields of both mechanical and aerospace engineering, and his current appointment is aerospace research engineer at the Air Force Research Laboratory. There, he has developed and sustained an independent research program since 2007. He is also an adjunct professor at the Air Force Institute of Technology.

Onome’s lengthy list of publications, conference proceedings and presentations and invited lectures make him a standout among the department’s young alumni. In 2019, Scott-Emuakpor received the Department of Mechanical and Aerospace Engineering Ralph Boyer Young Achiever Award, given to alumni who have made significant contributions in their profession before the age of 40. He has received other notable honors, including the Presidential Early Career Award for Scientists and Engineers, and was an invited participant in the National Academy of Engineering’s 2017 U.S. Frontiers of Engineering Symposium.

Major contributions have resulted from Onome’s research, which centers on high cycle fatigue, energy-based fatigue life prediction for engine materials and mechanics. He also serves the community by supporting the AFRL Summer Student Research Program and the local youth basketball program.


Prof. Leroy Long, Assistant Professor of Engineering Fundamentals at Embry-Riddle Aeronautical University

Leroy Long (MS Mechanical Engineering ‘11)

Dr. Leroy Long III is dedicated to educating the future generations of engineers. He is an assistant professor of engineering fundamental sat Embry-Riddle University, where he directs the Engineering, Arts & Sports Engagement (EASE) research team. Much of Dr. Long’s research focuses on social equity and racial justice, and the retention and career readiness of his students.

Dr. Long earned his Master’s in Mechanical Engineering at Ohio State. He also went on to earn his PhD in STEM Education with a focus on Engineering Education from the department of teaching and learning at Ohio State.

Dr. Long has led research funded by the NCAA to improve the well-being of the student-athlete through support of their career readiness. He has also served on two NSF advisory boards, and participated in NSF funded research to study factors that broaden minority student participation and Success in STEM fields. Dr. Long also took part in creating the Black In Engineering Organization, which provides Universities recommendations and resources for improving equity and fairness.

Dr. Long delivered the first presentation in a new seminar series that explores the greater impacts of mechanical and aerospace engineering. Find upcoming events in the "Societal Impacts of MAE" series here

Margaret Mkhosi

Margaret Mkhosi (MS Nuclear Engineering ’03, PhD Nuclear Engineering ’07)

Margaret holds the position of director at the Centre for Nuclear Safety & Security at South Africa’s National Nuclear Regulator.

She has an extraordinary story of rising from poverty in a remote South African village to obtaining a PhD in nuclear engineering at Ohio State. But she didn’t stop there: after her academic achievements, she returned home to lead nuclear safety programs and inspire the next generation.

Since graduation, Margaret’s accomplishments have included facilitating an interdisciplinary R&D program and developing and establishing an effective accident analysis unit for the National Nuclear Regulator. Her programs ensure a commitment to the health, safety and security of workers and complete care of the public and environment.

Margaret’s commitment to educational access led her to establish the Youth Technology Innovation Fund, as well as Charity at Home. She serves in Women in Nuclear Global and is a two-term president of Women in Nuclear South Africa.

Margaret graduated from the department with her master’s degree in nuclear engineering in 2003 and her PhD in the same in 2007. She also holds a master’s in physics from the University of North-West in South Africa and bachelor’s degrees in physics and education from University of Bophuthatswana in South Africa
