I'm a controls student at University of Dayton pursuing a PhD by applying developmental learning so robots can incrementally learn high dimension tasks. I was a DAGSI fellow, but am currently an Ohio Space Grant Consortium fellow. I also work at the Air Force Institute of Technology using real-time pan-tilt-zoom cameras to find wing shapes in flight or space boom deployment characteristics.
Professional Interests: Learning, controls, robotics
