My students have been very productive in the last year!
Here are their Drexel Research Day 2008 posters.

My former graduate student Jasper Zhang presented the poster

at the 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society in Vancouver.

My summer student Jon Bradshaw won the best poster award for the 2008 Engineering Cities REU program!
His poster was entitled

Check out "Level Set Morphing Goes to Hollywood!"

Here is some news about my US patent and
NSF grants: Math Images, Interactive Level Set Modeling and Self-organizing Shapes.


I am affiliated with the ACIN Program and the Drexel Engineering Cities Initiative.

I collaborate with three groups at Drexel:

and

I am currently on the Program Committee of
      the 2009 International Conference on Shape Modeling and Applications,
      the 7th Symposium on Geometry Processing,
      the 10th Eurographics - IEEE VGTC Symposium on Visualization,
      the IEEE/EG International Symposium on Volume Graphics and
      the IEEE Visualization 2008 Conference.

I am looking for a graduate student with training in biology and strong programming skills to work on a biological simulation research project.
Please contact me if you are a graduate student interested in conducting this kind of research.

Research Interests

The central focus of my research is 3D geometry. I am exploring and developing the methodologies needed for specifying the shape of 3D objects, and the algorithms needed to process, animate and analyze these shapes. The second component frequently found in my research is physics-based modeling. This work revolves around using physics and dynamic simulation to solve geometric and animation problems. Additionally, I am fascinated by dynamic processes that aggregate small-scale, local interactions to produce large-scale, macroscopic behavior and structures. I am also interested in the application of geometric modeling and analysis. These applications include computer-aided design, computer animation, segmentation, medical image analysis, scientific visualization and simulation.

My interests are evident in the research that I have conducted to date. These projects include the tessellation of complex surfaces with Steiner patches, development of an object-oriented modeling and animation system, computational animation techniques, deformable meshes for volume segmentation, a particle-based model for simulating cloth drape, fitting cloth models to 3D shapes, collision detection for augmented reality, multiresolution mesh extraction, parallel volume rendering, 3D scan conversion techniques, level set models for 3D metamorphosis, volume segmentation and surface editing, stochastic geometry for displacement mapping, contour-based surface reconstruction, network/graph visualization, simulation of chemotaxis-based cell aggregation/sorting and self-organizing geometric primitives.

I am currently involved in seven research projects:

My research is funded by the National Science Foundation, the US Army Research, Development & Engineering Command - CERDEC, and Drexel University.
