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, interactive free-form level set modeling, shape analysis of biomedical images and self-organizing geometric primitives.

I am currently involved in five research projects:

interactive, multiresolution level set modeling,

self-organizing geometric models,

shape and image analysis for medical imaging,

simulation of chemotaxis-based cell aggregation and sorting,

GPU-based wave propagation simulation and spectrum sensing.

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