I have recently been named Deputy Director of the CVDI.

My PhD student Linge Bai won the 2014 Jay Modi Memorial Award.

She also won the People's Choice Award at the recent CCI Day Ph.D. Research Poster competition.

My PhD student Linge Bai won a Best Poster Award at Drexel Research Day 2012 based on
the research she conducted at the Max Planck Institute for the Physics of Complex Systems in Dresden, Germany.

I am affiliated with the   Math Images Project, the   REThink Project, and the   Center for Visual and Decision Informatics.

I collaborate with five research teams:

I am currently on the Program Committee of
      the Generative and Developmental Systems Track of GECCO 2015
      the 2015 International Conference on Shape Modeling,
      the Morphogenetic Engineering Special Session of ECAL 2015 and
      the 2015 IEEE International Conference on Bioinformatics and Biomedicine.

I was the Local Organization Chair of the 2013 IEEE International Conference on Self-adaptive and Self-organizing Systems, which was held at Drexel in September 2013.

I have an opening for a CS PhD student, who has some training in biology, physics and/or 3D modeling, to work on a biological simulation / self-organization research project.
Please contact me if you have this kind of background and are interested in conducting this type of research.


Research Interests

A central theme in my research is 3D geometry. I am exploring and developing the algorithms needed to specify, process, animate and analyze 3D geometric objects. 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, as well as to model biological systems. Additionally, I am studying the dynamic processes that aggregate small-scale, local interactions to produce large-scale, self-organizing macroscopic behavior and structures.

With my background in computer graphics, animation and visualization, I am now focusing my research efforts on geometric biomedical computing. This is a research area that lies at the intersection of biology, medicine, engineering and computer science, and one that develops algorithms and software to solve geometry-related computing problems for a variety of biomedical applications.

I am currently involved in five research projects:

Here is an overview of my research activities/expertise.

My research is funded by the National Science Foundation and the Commonwealth of Pennsylvania.
