My research is on applied topology and more specifically, topological data analysis, which studies the shape of data. More precisely, it consists of
- combining ideas from topology, statistics and machine learning to develop new tools for summarizing and visualizing large, complex, high-dimensional data;
- developing a general framework which quantifies topological changes using ideas from algebraic topology, algebra and category theory; and
- working with collaborators to use these ideas to analyze data.
I am a researcher in the NSF-Simons Southeast Center for Mathematics and Biology. It is supported by at $10M grant from the National Science Foundation and Simons Foundation. Here are the announcements from Georgia Tech, the Simons Foundation, the National Science Foundation, and the University of Florida.
I am an Associate Editor of the SIAM Journal on Applied Algebra and Geometry (SIAGA).
I obtained my Ph.D. at the University of Toronto in 2003 and was a postdoc at the Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland from 2003 to 2005. From 2005 to 2015 I was a professor at Cleveland State University, and since 2015, I am a professor at the University of Florida.
