    About Me

    I am a postdoctoral researcher at the Institute of Discrete Mathematics at TU Graz, working with Mihyun Kang. I did my PhD in Combinatorics and Optimization at the University of Waterloo, under the supervision of Penny Haxell.

    With Joshua Erde and Mihyun Kang, I help organize the Graz Combinatorics Seminar. My research interests lie in extremal, probabilistic, and topological combinatorics. In particular, I am interested in transversals, matchings, independent sets, colorings, and connections to combinatorial optimization, algebraic topology, and statistical physics.
