Navid Aghasadeghi

Background

I received my B.S. in Electrical and Computer Engineering from the University of Texas at Austin in 2008 and my M.S. in the same field in 2010 from the University of Illinois at Urbana-Champaign. I am currently a Ph.D. student in the Electrical Engineering department at the University of Illinois at Urbana-Champaign where I work with Dr. Tim Bretl. I also collaborate with Dr. Eric Perreault and Dr. Levi Hargrove at the Rehabilitation Institute of Chicago. My PhD degree is supported by the NRSA predoctoral fellowship from the National Institute of Health.

Research Interests

My interests lie in robotics, control theory and machine learning with applications to building intelligent systems and robots. In particular, I am interested in using mathematical tools along with principles from neuroscience to model human perception and decision-making and subsequently design efficient and robust software systems and control algorithms for prosthetic devices and robotic systems.
