I am an algebraic topologist inspired by ideas from mathematical physics.

I'm currently finishing a combined Benjamin Peirce and NSF Postdoctoral Fellowship at Harvard. In Fall of 2018, I will be at the Newton Institute in Cambridge, England, and in the Spring of 2019, I will be at MSRI. In the Fall of 2019, I will be an Assistant Professor at Texas State University.

You may have also seen me in Bonn in summer of 2015, or around the Bay Area in spring of 2014, when I was an MSRI Postdoctoral Fellow.

## Statement of commitment to equity in mathematics

I support policies and activities meant to dissect and disarm mechanisms that lead to inequities in mathematical fields. To this end, I also support: conducting research into the sometimes subtle, sometimes not-so-subtle, ways in which various groups come to be underrepresented in mathematical fields; listening to needs of various communities and responding effectively to those needs; reflecting on personal actions and reactions; and enacting practices of equity in my day-to-day praxis.
