I started the Computer Graphics and Vision Lab at PSU after receiving my Ph.D. in Computer Science from the University of Wisconsin, Madison in 2010. My research interests include computer vision, computer graphics, applied machine learning, and human computer interaction.
Prospective PhD students I am looking for motivated students with strong mathematical and programming skills to work on exciting projects. I currently only have one new position available. If you are interested in working with me, please email me directly to discuss your interest before you apply.
