Bio

I am an Assistant Professor with the Department of Computer Science at Wayne State University. Before joining Wayne State University in 01/2021, I spent three wonderful years as a postdoctoral researcher with the Department of Computer Science at the University of Maryland, College Park, advised by Professor Matthias Zwicker. I obtained my B.E. (2009), M.E. (2012) and Ph.D. (2017) from Northwestern Polytechnical University in Pattern Recognition and Intelligent Systems. My research interests include 3D computer vision, digital geometry processing, and artificial intelligence.
