I am an assistant professor at Electrical and Computer Engineering Department, The University of New Mexico. I received my Ph.D degree in Computer Science with Department of Computer Science at The University of Texas at Dallas (UTD). My current research mostly focuses on computer graphics and related topics. More specifically, my research interests include deformable model, physics-based animation/simulation, medical imaging analysis and visualization. 
My name reads like Yin & Yang  in Mandarin if you read my first name first, which is a very famous concept in Chinese philosophy and also one of my main inspriration in my research and life.

Recent research 

Deformation streaming
Deformation streaming
Reduce the DOF number as well as the streaming data size in networked environment using different simulation strategy. Package delay can be well-handled based on the linearized time integration formulation. [video

Related paper: TOH13, MM13, HAVE13
Multi-domain subspace deformation
Extremely fast deformation simulation algorithm using domian decomposition. Subspaces are built locally with carefully-designed bases which do not cause any locking and over-constrainting problem. FE mesh over 200,000 elements can be simulated in real-time.  [video1] [video2] [video3]

Related paper: VR12 (Poster), TVCG13
Visualization of hunam tongue
Physics-based visualization combining modeling reduction and motion capture techniques: fast and plausiable visualization can be provided in real-time for specified hunman speech tasks. Comprehensive deformation analysis tool is also equipped in the framework. [video]

Related paper: SIGGRAPH12 (Poster), TVCG13
GPU-aided lung tumor tracking
Fast tracking lung tumor for patients with radiation therapy. Precisely and timely tracked tumor movement pattern could help dose delivery with higher accurately. 1000 time performance acceleration is achieved with GPU based SAT. [video]

Related paper: ASTRO10, PSIVT10, Red J.12
Spectral hybrid simulation
By assigning only rigid modes to regions of the FE mesh, fast hybrid simulation effect can be achieved. This is a natural extension of linear modal analysis with nice and symmetric formulation for both rigid and deformable regions. The properties of fast simulation of modal analysis is also perserved: yes, it is real-time. [video]
