About Me

I am a postdoc at the Max Planck Institute for mathematics in Leipzig, working in the math software group lead by Michael Joswig. I obtained my Ph.D. from Brown University under the supervision of Melody Chan. My research interests include tropical geometry and combinatorics. I did my undergraduate studies at Smith College.
