My recent paper "Lymph Node Metastasis Status in Breast Carcinoma Can Be Predicted via Image Analysis of Tumor Histology" (with M. Zarella, M.A. Reza, A. Milutinovic and F.U. Garcia) was the featured article on www.aqch.com in November 2015.

I co-organized, with the Drexel Cybersecurity Institute, a symposium on Big Data, Cybersecurity and Privacy.

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

She also won the People's Choice Award at the 2014 CCI Day Ph.D. Research Poster competition.

I am affiliated with the   Math Images Project, the   REThink Project, the   Center for Visual and Decision Informatics,
and the Center for Biological Discovery from Big Data.

I collaborate with five research teams:

I am currently on the Program Committee of
      the 2016 Genetic and Evolutionary Computation Conference (GECCO) and
      the Fifteenth Conference on the Synthesis and Simulation of Living Systems (ALIFE XV).

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 two openings for CS PhD students.
The first position requires experience with geometric modeling, optimization and numerical methods and will focus on developing textile design technologies.
The student for the second position should have some training in biology, physics and/or 3D modeling, and will work on a biological simulation / self-organization research project.
Please contact me if you have this kind of expertise and are interested in conducting this type of PhD research.

More information about these projects can be found here.


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.
