Rajko Nenadov
I am a Lecturer in the School of Computer Science at the University of Auckland, New Zealand.
I obtained PhD from ETH Zurich in 2016, under the supervision of Angelika Steger. I spent two years as a postdoc at the School of Mathematical Sciences at Monash University (Melbourne, Australia) hosted by Jane Gao and Nick Wormald, and another year and half back at ETH, where I was hosted by Benny Sudakov. The following four years I was a software engineer at Google Zurich, working mostly on Search Ranking algorithms. As of July 2023, I'm back in academia!
My principal research interests are in discrete mathematics and theoretical computer science, particularly algorithmic and combinatorial properties of random and pseudorandom discrete structures, applications of (pseudo)randomness in theoretical computer science, probabilistic methods in combinatorics, extremal graph theory, Ramsey theory, and combinatorial games.
