Lab Instructor/Principal Investigator

Dr. Jinsook Roh

Dr. Jinsook Roh is an Assistant Professor in the Department of Biomedical Engineering at the University of Houston, TX. Her research program focuses on understanding the neural mechanisms of motor coordination in healthy and pathological populations (esp. stroke) and translating the resultant scientific findings to develop new therapeutic strategies to improve motor function after neural injuries. She holds her graduate degree in Systems and Computational Neurosciences at Massachusetts Institute of Technology (MIT), with undergraduate Physics background.

Before joining UH, she worked as an Assistant Professor in Kinesiology at Temple University. She completed a post-doctoral fellowship at Rehabilitation Institute of Chicago (#1 rehabilitation research hospital for > 25 years in the US) and at Northwestern University. She has implemented research projects to identify and characterize abnormalities in synergistic muscle coordination in stroke survivors and to develop novel rehabilitation methods. Dr. Roh received several research awards and fellowships that include American Heart Association Postdoctoral Fellowship (2010-20120). Dr. Roh has been performing research projects supported by extramural funds, such as National Center for Neuromodulation for Rehabilitation (NC NM4R) Pilot Grant as the PI, American Heart Association Scientist Development Grant as the PI, NIH R01 as a co-I, and one international grant from National Rehabilitation Center in South Korea as the co-PI. She also likes teaching and mentoring students with diverse experiences. When she finds free time, she enjoys cooking Korean food, walking with her husband, and chatting with her friends with diverse backgrounds.

In her life, she found that the source of pure joy for her is to see positive changes in people’s life. That finding motivates her to do her science in human motor rehabilitation engineering.
