Until August 2018 I was a postdoc in the Discrete and Computational Geometry Group of János Pach at EPFL. I did my Phd at UBC in Vancouver under the supervision of József Solymosi. My research involves algebraic methods in combinatorial geometry.
From August 2018, I am an assistant professor at Baruch College, which is part of the City University of New York.
