Hello! I am a research fellow at the University of Zagreb (supported by the EU's Widening Fellowship), working in extremal and probabilistic combinatorics. I completed my PhD at ETH Zurich in 2018 under the supervision of Benny Sudakov. From 2018 until 2021 I was a Research Fellow at Monash University.

Topics I have recently worked on include asymptotic enumeration, sparse Ramsey theory, arithmetic Ramsey theory, random and pseudorandom graphs. I love hearing about new problems and applying techinques from e.g. algebra and probability, so feel free to contact me on nina.kamcev at
