Brief Bio
I received my Bachelor and Master Degree in Computer Science from Shanghai Jiaotong University(SJTU) in 2006 and 2009. I worked in Ubisoft Shanghai during 2005 and 2006 and participated in developing three games: "Ghost Recon Advanced WarFighter Xbox", "Ghost Recon Advanced WarFighter PS2" and "Brother In Arms D-Day PSP". With strong love of computer graphics, I continued my research career as a PhD student in Georgia Institute of Technology. I'm extremely interested in physically-based animation, such as fluid simulation, character animation, etc. I work with Greg Turk and Karen Liu.
Research Interests
Computer graphics, physics simulation, animation control, real-time rendering, global illumination, computational fluid dynamics and numerical algorithms.

Other Projects
Real fluid phenomena often present multi-scale behavior, such as tiny splashes and foams in the ocean and small vortices near the bank of a wide river. It requires sufficiently fine grids and long computational time in the simulation to get adequately resolved solution. We present a new method to address this issue by solving Navier-Stokes equations on multiple layers of grids with different resolutions or discretizations. It combines the respective advantages of various grid types (discretizations), to catch the multi-scale behavior of fluids and optimizes the computational resources. Here is a link to the SCA 2008 poster "Fluid Animation with Multi-layer Grids". |

3diya.com is a start-up company I founded with several friends. I worked as the CTO in the company. It is a 3D website on which you can design your home virtually. I implemented it using C++ and openGL and compiled it as a small ActiveX plug-in. Once you installed the plug-in, you can create your own virtual house and make the interior decoration. Although I left the company to pursue my research career in Gatech, the development of this website continues. The users now can create outdoor scenes as well. Please visit www.3diya.com if you're interested. |

I participated in the development of "Ghost Recon Advanced War Fighter" both on Xbox and PS2 when I was an intern in Ubisoft. In these two projects, I mainly worked on the sound engine implementation and optimization. I implemented the new feature "Dynamic Mixing" for the sound designers and ported the whole sound engine from the EE (main CPU on PS2) to IOP (the coprocessor on PS2) in order to minimize the data transfer beteen EE and IOP. |

I worked as a graphics engineer in this project. With the guidance of my mentors, Xiaoyue Xu and Zheng Ma, I implemented several new features on the fix-pipeline system, such as full screen glow effect and multi-layer terrain, which I believed were never seen before on PSP games at that time and became selling points of the game. I also optimized the rendering system for static meshes, achieving 50-100 times speed up compared to the previous implementation. |
