Research

My research interests are in computational topology and geometry, combinatorial topology, and applied topology (in particular to data analysis and to sensor networks).

I am a member of the Pattern Analysis Lab.

Here is a (potentially outdated) research statement, my PhD thesis, and a related research highlight.
