I am a tenure-track Associate Professor at Yale-NUS College (Singapore), holding a joint appointment with NUS School of Computing, where I am also a Co-PI at NUS Crystal Centre. In 2015-2018, I was a faculty at University College London. Prior to that, I was a postdoc at IMDEA Software Institute. I hold a PhD in Computer Science from KU Leuven, and MSc in mathematics from Saint Petersburg State University. Before joining academia I worked as a software engineer at JetBrains in IntelliJ IDEA team.

I do research in programming language theory, including, but not limited to types, semantics, software verification, and program synthesis. Lately, I have been mostly focusing on developing sound and scalable methodologies for building provably correct concurrent and distributed systems.
