I was a post-doctoral fellow in the Vision and Image Processing Lab from 10/2011-12/2014. I collaborated with the professors David Clausi, Alexander Wong, John Zelek, and Steven Waslander in the areas of image processing, computer vision, and robotics. Please find a selection of research projects I am/was involved with listed below.
