I'm a final year PhD student at Meta AI (FAIR) and University College London (UCL). At UCL, I am supervised by Tim Rocktäschel at UCL Deciding, Acting, and Reasoning with Knowledge (DARK) Lab. I am also part of the ELLIS PhD & Postdoc Program.

I hold an MSc in Computer Science degree from the University of Oxford where I worked in the Whiteson Research Lab advised by Shimon Whiteson. Prior to that, I obtained Master’s and Bachelor’s degrees from Yerevan State University in Informatics and Applied Mathematics. I have previously held research and development engineering positions at Reddit, Mentor, Toptal and USC Information Sciences Institute.

My research aims to train and evaluate robust AI agents capable of adapting to new environments and coordinating with others. To achieve this, I use techniques from reinforcement learning, open-endedness, and multi-agent learning. My most recent work has centered on using these methodologies to improve the robustness and safety of LLMs.
