## About Me

I'm currently a Benjamin Peirce Fellow and NSF Postdoctoral Fellow at Harvard. I received my Ph.D. in 2013 from Northwestern University, where my advisor was Kevin Costello. 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.

My research is in algebraic topology with an emphasis on mathematical physics.

## Statement of commitment to emerging mathematicians

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.
