My PhD student Manolya Eyiyurekli presented the poster

Interactive Free-Form Level-Set Surface-Editing Operators

at the ACM SIGGRAPH Symposium on Interactive 3D Graphics and Games held in Boston.

My former graduate student Jasper Zhang presented the poster

A Study of Shape Distributions for Estimating Histologic Grade

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

Here is some news about my US patent and
NSF grants: CAREER Award, Math Images and Interactive Level Set Modeling.

I am affiliated with the
Math Images Project and the ACIN Program.

I collaborate with three groups at Drexel:

I am currently on the Program Committee of
      the 2009 International Conference on Shape Modeling and Applications,
      the 2009 Spring Conference on Computer Graphics,
      the 7th Symposium on Geometry Processing and
      the 5th International Symposium on Visual Computing.

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 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.
