Presonal Summeary

I finished my Ph.D. in September 2012 under the supervision of Prof. Takeo Igarashi. Currently, I am a postdoctoral internship researcher at Autodesk Research in Toronto (working with Ryan Schmidt). I am interested in computer graphics, interactive design interface and mechanical engineering especially :

Integrated Design, Simulation and Interaction
Interactive simulation
Fabrication
Finite Element Methods
Biomechanical Simulation

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.
