Brenna Argall, PhD
Lab Director
Dr. Argall is an associate professor of Mechanical Engineering, Computer Science, and Physical Medicine & Rehabilitation at Northwestern University. She is founder and director of the assistive & rehabilitation robotics laboratory (argallab) at the Shirley Ryan AbilityLab (formerly the Rehabilitation Institute of Chicago), the nation’s premier rehabilitation hospital. The mission of the argallab is to advance human ability, by leveraging robotics autonomy.
Argall is an elected fellow of the American Institute for Medical and Biological Engineering (AIMBE), a recipient of the NSF CAREER award, and was named one of the 40 under 40 by Crain’s Chicago Business. Her Ph.D. in Robotics (2009) was received from the Robotics Institute at Carnegie Mellon University, where she was a member of the CORAL Research Group. Her B.S. in Mathematics (2002) also was received from Carnegie Mellon, where she minored in Music and Biological Sciences. Prior to joining Northwestern and RIC, she was a postdoctoral fellow (2009-2011) in the Learning Algorithms and Systems Laboratory at the École Polytechnique Fédérale de Lausanne (EPFL). Prior to graduate school she held a Computational Biology position in the Laboratory of Brain & Cognition at the National Institutes of Health (NIH). More recently (2019) she was a visiting Research Fellow at the Wyss Center for Bio and Neuroengineering in Geneva, Switzerland.

Larisa Loke
PhD Student, Mechanical Engineering
Larisa is a doctoral student in the Mechanical Engineering Department at Northwestern University. She attended Nanyang Technological University, Singapore from 2016 to 2020 and graduated with a BEng in Mechanical Engineering. During this time, she worked on short research projects in the Rehabilitation Research Institution of Singapore under the supervision of Prof. Ang Wei Tech. One project was improving a balance trainer for the elderly, and another was a force sensor design to monitor activities of daily living. In 2019, she did her final year thesis project at the Robotics Institute at Carnegie Mellon University, where she worked in Dr. John M. Dolan’s lab. Her research project investigated the use of synthetic data to train CNNs for detection of rare traffic signs for applications in autonomous driving.
