I am a post-doctoral researcher at the School of Mathematics at Tel Aviv University hosted by Noga Alon, Michael Krivelevich, and Ron Peled. I am also a junior research fellow at Trinity College, Cambridge. My areas of interest include various branches of extremal and probabilistic combinatorics, such as extremal (hyper)graph theory, the theory of random graphs, and Ramsey theory, as well as some topics in additive number theory. I completed my PhD at the University of Illinois at Urbana-Champaign in 2010 under the supervision of Jozsi Balogh. Prior to coming to Urbana-Champaign, I received master's degrees in mathematics and computer science from the Unversity of Wroclaw.
