I’m a research scientist at Samsung AI Center in Cambridge, UK. I like using mathematics to make things work in practice, especially in deep learning applications. Beside doing research, I serve as an Action Editor for TMLR, tweet about interesting papers, and give talks about my research. In 2023, I was lucky to receive the Outsdanding Paper Award together with Aaron Defazio for our work on adaptive methods.

Before joining Samsung, I did a postdoc at Inria Sierra with Alexandre d’Aspremont and Francis Bach. I received my PhD in from KAUST, where I worked under the supervision of Peter Richtárik on optimization theory and its applications in machine learning. In 2020, I also interned at Google Brain. I obtained my double degree MSc diploma from École Normale Supérieure Paris-Saclay and Paris-Dauphine, and a BSc from Moscow Institute of Physics and Technology.

My interests and hobbies tend to change every couple of years or so. Right now, I’m studying electronic music production using Ableton Live, and I hope to release some music online in the future. Feel free to shoot me an email if you want to chat in person about research or music, go to a museum, or maybe just take a walk in London!

Note that I’m currently not taking any interns.

Working on federated learning and embedded AI systems as a member of the Distributed AI team.

Postdoc

Conducted research on adaptive, second-order, and distributed optimization.

Our work on an extension of DoG with weighted gradients got accepted for presentation at NeurIPS this year! If you want to try our method, a pytorch implementation is available on github. I hope to see more papers building upon DoG, DoWG, D-Adaptation, and Prodigy, we have barely scratched the surface on what can be done, and some of these methods are already being used in practice.

I’m delighted to share that Aaron Defazio and I received the ICML Outstanding Paper Award for our work on D-Adaptation. The associated github repository of our paper has been quite popular and we are working hard on making extensions that will make adaptive methods even more useful for deep learning. Our first extension, Prodigy, is available on github as well and has been performing even better than D-Adaptation in our experiments. Expect more updates from us pretty soon!
