Jonathon Schofield
Principal Investigator
Dr. Schofield works to improve user acceptance and promote the seamless integration of humans and assistive medical devices, leveraging techniques in bio-robotic control and feedback, sensory-motor neural interfaces, and cognitive-perceptual neurosciences. The BEAR Lab performs interdisciplinary research at the interface of mechanical and electrical engineering, neurosciences and rehabilitation medicine to address unmet clinical needs and understand how humans engage with intelligent technologies such as robotic prostheses and powered exoskeleton orthoses, among many others.

Patrick Trieu
PhD Student, Biomedical Engineering
Bachelor's in Mechanical Engineering
Master's in Mechanical Engineering
Patrick's goal is to investigate how a user's sense of embodiment over an assistive device, or their belief that the device is a part of their body, can be simulated in a virtual environment.

Eden Winslow
PhD Candidate, Biomedical Engineering
Bachelor's in Biomedical and Mechanical Engineering
Eden is interested in medical device design and neuro-prosthetic control. Her goal is to improve prosthetic arm control for pediatric patients. Her current project involves investigating the feasibility of decoding proportional force and position information from the muscles of children born without a hand.
