Hi, I'm Alex!

I am a second-year math PhD student at ISTA in the research group of Matthew Kwan. Before coming to ISTA, I completed my masters at IMPA (Rio de Janeiro).

My research interests include extremal and probabilistic combinatorics as well as its interactions with probability and number theory.
