Hello! I am currently a second year PhD student at ETH Zurich, under the supervision of Benny Sudakov. My main research interests are in extremal and probabilistic combinatorics, often involving graph theory, additive combinatorics, Ramsey theory, or pattern containment. I also am interested in discrete geometry, although I have yet to publish anything in this area.

Email: zach.hunter@math.ethz.edu -- I welcome any questions/comments about my work.
