I am broadly interested in geometric and topological data analysis, an area of mathematics at the intersection of many mathematical fields: geometry, topology, linear algebra, optimization, computing, and machine learning. I am particularly interested in developing and applying tools from computational geometry and topology to a wide variety of data sets from hyperspectral imagery to biological aggregations.

I am a founder of the Women in Computational Topology (WinCompTop) listserv ( join by sending a blank email to:<WinCompTop+subscribe@groups.google.com>) and was the PI of the NSF grant to fund the inaugural WinCompTop Workshop at the IMA in August of 2016. For a description of the program, see the write-up in the AWM newsletter.

I also am the PI of the NSF-CBMS grant to fund the regional research conference Topological Data Analysis: Theory and Applications held at Macalester College in June of 2017.
