I am a tenuretrack assistant professor at Brown University. From 2012 to 2015 I was an NSF Postdoctoral Fellow and Lecturer in the mathematics department at Harvard. I got my PhD from UC Berkeley in 2012, advised by Bernd
Sturmfels.
I am interested in combinatorial algebraic geometry, particularly: algebraic curves and their moduli, graph theory, and
tropical geometry.
I am supported by NSF DMS1701924 and a 2018 Sloan Research Fellowship. In Spring 2018 I was supported by a Henry Merritt Wriston Fellowship. In Fall 2018 I will be on junior sabbatical at ICERM.
Here is my CV.
Here are my profiles on Google Scholar and MathSciNet.
