I am a graduate student in mathematics at Yale University. My advisor is Sam Payne. My research interests include algebraic and tropical geometry.  Starting in August 2018, I will be a Van Vleck Visiting Assistant Professor at the University of Wisconsin, Madison.

Student Tropical and Algebraic Geometry Seminar

Together with Jeremy Usatine, we organized the Student Tropical Algebraic Geometry Seminar (STAGS), a conference on tropical geometry and releated areas aimed at graduate students and early postdoctoral fellows. More information can be found at the conference webpage here.
