Meet the Research Team

Chris Cherry, PhD

Dr. Chris Cherry is a Professor at the University of Tennessee and is one of the foremost researchers on light electric mobility. He received his PhD in Civil Engineering from the University of California, Berkeley in 2007 with a dissertation focused on e-bikes in China. He has published extensively in research areas that include non-motorized safety and system design; the role of e-bikes, micromobility, and other emerging technologies on the transportation system; planning and economics; and sustainable transportation. He leads the Light Electric Vehicle Education and Research (LEVER) Initiative, a consortium of universities and industry to explore the role of emerging and potentially disruptive classes of electric vehicles on safety, sustainability, and health. He also chairs the Society of Automotive Engineers Micromobility Vehicles Committee and co-chairs the Transportation Research Board joint subcommittee on Emerging Vehicle Technologies.

Wei Gao, PhD

Dr. Wei Gao is currently an Associate Professor in the Department of Electrical and Computer Engineering at University of Pittsburgh. His research interests include wireless and mobile network systems, mobile and edge computing, Internet of Things, cyber-physical systems and big data. He has published more than 60 papers at top-tier journals and conference proceedings in these areas, and has served on the editorial board of multiple top-tier journals and the organizing and technical program committees of many conferences. He received the US National Science Foundation (NSF) CAREER Award in 2016.

John MacArthur

John MacArthur is a Sustainable Transportation Program Manager at TREC - Portland State University. He is active in research related to sustainable transportation, particularly in the areas of transportation electrification, e-bikes, bike share, transit, and the relationship between transportation and public health. He has worked for 25 years in the environmental and sustainability field. He is also the co-director of the Light Electric Vehicle Education and Research (LEVER) Initiative and the Vice Chair of SAE’s Powered Micromobility Vehicles Committee. He has a B.S. in Civil Engineering from Lehigh University and a M.S. in Environmental Health Sciences from the University of Michigan, School of Public Health.

Mojdeh Azad

Mojdeh is currently a PhD candidate in Civil Engineering-Transportation and an MS candidate in Statistics at the University of Tennessee, Knoxville, working under the supervision of Dr. Chris Cherry. Her primary research interests include sustainable last-mile delivery, pedestrian and bicycle safety, and using new technologies, big data, and machine learning in policymaking and planning. She is a LEED Green Associate accredited professional, holds a MArch in Architecture from the University of New Mexico, and was a visiting student at the MIT Center for Transportation and Logistics (CTL) during Fall 2019.

Renfan Yang

Renfan Yang is a second-year PhD student within the Swanson School of Engineering at the University of Pittsburgh. His research interests center around mobile connected health and applications in the Internet of Things. After Renfan graduated in 2018 with an MS degree in Electrical Engineering from Pitt, he decided to explore further and began working under the supervision of Dr. Wei Gao. His other interests include pattern recognition and network security.

Mike McQueen

Mike is second year graduate student in the Civil Engineering MS program, Transportation specialization, at Portland State University. He is an FHWA Dwight D. Eisenhower Transportation fellow, a Young Professionals in Transportation (YPT) StreetLight Graduate fellow, and a National Institute for Transportation and Communities (NITC) scholar. His research interests include e-bikes, bike share, and multimodality. Mike is a native of Detroit, Michigan, and became interested in urban transportation topics after interning in Paris, France for six months. In his spare time, he enjoys yoga, virtual air traffic simulation, and riding BIKETOWN.

Meet Our Partners

Portland State University is home to the Transportation Research and Education Center (TREC), one of 7 transportation research centers nationwide designated by the U.S. Department of Transportation.

Recognizing the need to develop innovative solutions to transportation problems, the faculty in CEE’s Transportation Engineering and Science Program (TESP) is actively involved in educating the transportation workforce of the future, conducting research on transportation innovations, and disseminating knowledge to researchers and practitioners.

Since its founding in 1893 by two legends, George Westinghouse and Reginald Fessenden, the Department of Electrical and Computer Engineering at Pitt has excelled in education, research, and service. Today, the department features innovative undergraduate and graduate programs and world-class research centers and labs, combining theory with practice at the nexus of computer and electrical engineering, for its students to learn, develop, and lead lives of impact.

Bosch eBike Systems was founded in 2009, with the first drive system already launching at Eurobike in 2010. Since then, eBikes have been "epowered by Bosch". Right from the start, Bosch benefited from the experience gained in the automotive and motorcycle sectors and its great repository of technological expertise.

The Light Electric Vehicle Education and Research (LEVER) Initiative is a consortium of Light Electric Vehicle (LEV) researchers and educators that currently includes faculty and staff from University of Tennessee, Portland State University, and Monash University. LEVER started in 2014 to bring together some of the leading researchers in the field to collectively answer some of the biggest questions related to these emerging vehicles.

The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..." NSF is vital because it supports basic research and people to create knowledge that transforms the future.
