biography

I am a Full Professor of Computer Science at University of Houston (UH). I am also the Director of Graduate Studies at UH Computer Science Department and the Founding Director of the UH Computer Graphics and Interactive Media (CGIM) Lab. I earned Ph.D. in Computer Science at the Integrated Media System Center (NSF ERC) and Department of Computer Science at the University of Southern California in 2006. I also completed B.S. degree in Mathematics from Xiamen University (China), and M.S. in Computer Science from Peking University (China). Over the years, I've worked at the Founder Research and Development Center (China) and AT&T Shannon Research Lab.

My research interests are in the broad areas of computer graphics, computer animation, human computer interaction, virtual human modeling and animation, and visual computing for biomedical/healthcare informatics. I am the recipient of ACM ICMI Ten Year Technical Impact Award, UH Teaching Excellence Award, Google Faculty Research Award, UHCS Faculty Academic Excellence Award, and NSFC Overseas and Hong Kong/Macau Young Scholars Collaborative Research Award. Besides the CASA 2014 conference general co-chair and SCA 2015 conference general co-chair, I currently serve as an Associate Editor of several journals including Computer Graphics Forum, and Computer Animation and Virtual Worlds Journal. My research has been funded by NSF, NIH, NASA, DOD, Texas NHARP, and various industry sources (Google, Nokia, NVidia, etc). I am a senior member of ACM and a senior member of IEEE.

Research Opportunities

I am constantly looking for new graduate or undergraduate students to join my group! Self-Motivated students with solid math, vision, or graphics background are encouraged to apply. If you are already a current MS or PhD student in UH Computer Science program and would like to work with me, please make sure to take COSC6372 and/or COSC6356 courses.

Understand Human Behaviors in Multiparty Conversations

Quantifying, understanding, and modeling human behaviors and gestures when they are involved with multiparty conversations

Interactive Cage Generation for Deformation

An efficient complete pipeline to generate high quality cages for 3D models with arbitrary topological complexities, including high genus or complex models.

Interactive Mechanism Modeling from Multi-view Images

development of a novel interactive mechanism modeling approach based on multi-view images including interactive 3D modeling and stochastic motion parameter estimation.

Hexahedral Mesh Re-parameterization from Aligned Base Domains

A first and complete pipeline to optimize the global structure of a hex-mesh, by identifying and removing those valid removal base-complex sheets that contain misaligned singularities.

Robust and Accurate Skeletal Rigging from Mesh Sequences

Using the input of an animated mesh sequence, this approach can automatically extract its optimal skeleton structure, joint positions, linear blend skinning weights, and the corresponding bone transformations.

Two-layer Sparse Compression of Dense-Weight Blend Skinning

It introduces an efficient two-layer sparse compression technique to substantially reduce the computational cost of a dense-weight skinning model, with insignificant loss of its visual quality.

Smooth Skinning Decomposition with Rigid Bones

The SSDR model can effectively approximate the skin deformation of nearly articulated models as well as highly deformable models by a low number of rigid bones and a sparse, convex bone-vertex weight map.

Eye and Head Animations

Data-driven synthesis algorithms for realistic and coordinated eye and head movements based on (live or pre-recorded) speech input

Realistic Traffic Simulation

Design of novel and efficient algorithms and systems to simulate large-scale realistic traffic in various road and urban settings.

Creative Virtual Tree Modeling

A new method to efficiently generate a set of morphologically diverse and inspiring virtual trees through hierarchical topology-preserving blending, aiming to facilitate designers' creativity production.
