My PhD student Levi Kapplani Maharaj and others have published a paper on generating yarn topology graphs for knitted fabrics.

My PhD student Joel Pepper has been awarded an NSF Graduate Research Fellowship and
the best student paper award at the 2021 ACM/IEEE Joint Conference on Digital Libraries!

I am guest co-editing (along with Jim McCann of CMU and Mariana Popescu of ETH) a special issue of the journal Computer Aided Design
on Computational Modeling, Design and Fabrication for Textiles.

I have recently joined the editorial board of the International Journal of Modeling and Optimization.

My former MS student Rafael Campos has been profiled on the CCI web site.

I was part of the Drexel team that was awarded one of the National Institutes for Manufacturing Innovation!
Called AFFOA, the institute focuses on advanced fibers and textiles and is led by MIT.
Go here for more information.
AFFOA and the State of Pennsylvania has established a Fabric Discovery Center at Drexel.
Here is a recent story that describes the research being conducted at the Center for Functional Fabrics.

Enjoy some "math humor"!


I am affiliated with the Metadata Research Center and the Center for Biological Discovery from Big Data.

I collaborate with four research teams:

I am the Program Co-Chair for the 2022 7th International Conference on Biomedical Signal and Image Processing.
I am currently on the Program Committee of
      the 2022 International Conference on System Modeling and Optimization
      and the 2022 IEEE International Conference on Bioinformatics and Biomedicine.


Research Interests

Geometry is the technical thread that runs through most of my research. This may include geometric computation, geometric modeling, and geometric analysis.
Having studied physics as an undergraduate, physics-based modeling also is a frequent theme in my research, which can be seen in my energy-based optimization and simulation work.

Since I am fascinated by living systems and how they develop, I have worked extensively with biologists, biomedical engineers and physicians. This interest has led to my research efforts in 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 intrigued by the dynamic processes that aggregate small-scale, local interactions to produce large-scale, self-organizing macroscopic behavior and structures.

I have also returned to my technical roots (cloth modeling) by getting involved with the research at the Center for Functional Fabrics.
I am helping to develop computational technologies needed for the design of advanced textiles.

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 US Army Manufacturing Technology Program.
