Internship Opportunity

I am looking for Ph.D students who are interested in doing a research internship at Autodesk Research in Toronto Canada. The applicant should have background of computer graphics and be highly motivated to do a leading edge research project in the field of computational fabrication (geometry processing, physics simulation, shape analysis, visualization, HCI...). If you are interested, please send me an email (with your CV) to set up an appointment.

News

Feb. 2015 I gave an invited talk at IST Austria
Dec. 2014 I will serve on the International Program Committee of Pacific Graphics 2015
Nov. 2014 I will serve on the International Program Committee of SIGGRAPH 2015
Sep. 2014 I will take on a research scientist position at Autodesk Research from March 2015

About Me

I finished my Ph.D. in September 2012 under the supervision of Prof. Takeo Igarashi. Currently, I am a postdoctoral researcher at Disney Research in Zurich. Before that, I worked for Autodesk Research in Toronto (with Ryan Schmidt) for one year. When I was a master's student, I visited the applied mathematic department in TU Delft (Netherland) and worked with Prof. Kees Oosterlee and Prof. Scott MacLachlan. After started my Ph.D, I visited Columbia University in New York and work with Danny Kaufman and Prof. Eitan Grinspun. in another research visit in my Ph.D, I collaborated with Prof. Niloy Mitra at the University Collage London. In addition, I won an internship at Microsoft Research Asia (working with Weiwei Xu and Xin Tong) in February 2012.

I am interested in computer graphics, interactive design interface and mechanical engineering, especially:
