David Caldwell performed his dissertation research in neurosciences through the Department of Bioengineering under the mentorship of Jeffrey Ojemann, M.D. in the Department of Neurological Surgery and Rajesh Rao, Ph.D. in the School of Computer Science and Engineering. David engineered new approaches for targeted direct electrical stimulation of the brain. His work was interdisciplinary and involved working with patients undergoing brain surgery, in vitro systems, computational modeling, and electrical device circuit design. David’s research was highly collaborative and involved a summer spent performing research at the University of Freiburg, in Germany. The neuroprosthetic devices he developed are leading the way to help treat stroke and other brain injuries. David has continued research while performing clerkships. In one project addressing craniectomy methods, David developed software to perform quantitative image analysis on CT scans. In another project, David addressed disparities in clinical trials research and developed software to analyze a large clinical trials database.
