My research interests dwell in the area of the programming language design and implementation. Currently, I am focusing on developing scalable and sound methodologies for reasoning about concurrent and distributed programs.

I am a member of the Programming Principles, Logic and Verification group at the Department of Computer Science of University College London. Prior to joining UCL, from December 2012 to October 2015, I was a postdoc at IMDEA Software Institute. From November 2008 to November 2012, I was a research assistant in the CS Department of KU Leuven, where I obtained my PhD. During my doctoral studies I was a visiting PhD fellow in the Department of Computer Science of Aarhus University and a research intern in the PPT group at MSR Cambridge. I got my MSc degree in Mathematics and CS in 2008 from Dept. of Mathematics and Mechanics of Saint Petersburg State University. Before joining academia I worked as a software developer at JetBrains.

I'm on Twitter as @ilyasergey. I publish random thoughts about CS and academia in my Technical Blog (more posts to come soon). Some pictures from my travels and other events can be found on Instagram.

With the recently increased interest in the CS community to concurrency verification, this slide, which I've made sometime ago and which depicts the "flow of ideas" between modern concurrency logics, became very popular, so I decided to put it online for anyone who might want to use it in a presentation. I will keep it updated with more logics to come (and they will...). Feel free to drop me a line if you need the diagram's sources or want me to add your favourite logic, which is missing.

I am married to CG artist Lilia Anisimova.

Here is my "official" photo, suitable appropriate occasions. Yet another picture of mine by Jorge Cham, for I have contributed to the PHD Movie 2 on Kickstarter.
