biography

I am an Associate 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.

selected current projects

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.

Perceptually Guided Facial Animation

A perceptually guided computational framework is introduced to generate expressive facial animation, and quantitatively and automatically evaluate visual speech animation.

Eye and Head Animations

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

Visual Speech Animation Synthesis

Automated algorithms and systems to generate expressive visual speech animations based on novel typed or spoken input

Blendshape Facial Animation

Algorithms for automating or reducing time-consuming tuning efforts of the blendshape animation approach, including target interference reducing, cross-model mapping, and model construction.

Human Motion Compression and Retrieval

Effective algorithms for compressing and retrieving character motions by hierarchically extracting meaningful motion patterns from dataset, or by performing sparse dictionary learning from dataset.

Visual-Haptic Interfacing for Robot-Assisted Minimally Invasive Cardiac Surgery

A novel human-in-the-loop, visual haptic interfacing system for planning and performing real-time MRI guided, robot-assisted, minimally invasive surgical interventions on the beating heart, with particular focus on aortic valve implantations.
