Head of AI Research

Tl;dr

I am Head of AI Research at Tinkoff, an AI-first fintech company. Our team is focused on the CV, NLP, RL, and RecSys domains to advance the AI field and create novel technical solutions. We also frequently work with students through TLab.

My own line of research is mainly focused on sequential decision-making under uncertainty, ML robustness, and evaluation correctness. Besides that, I periodically help with Tinkoff.AI meetups and the ML Profession Framework.

In my spare time, I actively contribute to open source projects and lead the development of Catalyst, an open-source PyTorch framework for deep learning research and development.

Love traveling, sun and sea – write about them occasionally.
