Biography

Christopher J. Rozell received a B.S.E. degree in Computer Engineering and a B.F.A. degree in Music in 2000 from the University of Michigan, received M.S. and Ph.D. degrees in Electrical Engineering in 2002 and 2007 from Rice University, and was a postdoctoral scholar at the Redwood Center for Theoretical Neuroscience at the University of California, Berkeley.

Dr. Rozell's research interests are in computational neuroengineering, an intersection of neuroscience, data science, neurotechnology and computational modeling that advances the understanding of brain function and the design of effective interventions. His research has a particular focus on exploiting closed-loop interactions between biological and artificial intelligence to create precision models and algorithms, with a clinical focus on psychiatric disorders such as treatment resistant depression.

His scholarly activity also includes research and creative work that advances our understanding of the societal impacts of emerging technologies such as neurotechnology and AI.

Dr. Rozell is proud to be a first-generation scholar who is committed to accessibility in our scientific communities. He is a co-founder and member of the Board of Directors of Neuromatch, Inc., a global nonprofit increasing access to scientific knowledge.
