Jyh-Ming Lien Assistant Professor Contact info: Office: ENGR 4442 Department of Computer Science George Mason University, MSN 4A5 Fairfax, VA, 22030, USA http://cs.gmu.edu/~jmlien/ jmlien@cs.gmu.edu phone: (703) 993-9546 (Note: Email is the best way to contact me) visiting me? here is the direction office hours: on leave (Spring 2012) I direct the Motion and Shape Computing (MASC) Group. Visit MASC group project page for our most recent research and publications. Our research goal is to develop efficient, robust and practical algorithms for representing, manipulating and analyzing massive geometric data of shape and motion. Our research finds applications in the areas of computational geometry, computer graphics, GIS, visualization and robotics. I also organize GRAND seminar. If you are visiting DC area, I would certainly love to have you stop by and give a talk.
