Bhaskar Kataria

I am a third-year PhD student in Computer Science at Cornell University, advised by Professor Rachee Singh. My current research focuses on intelligent agents for endovascular surgery through Project Waldo, alongside systems for efficient LLM agent training, including stateful caching of tool calls. I have also worked on GPU storage acceleration, reconfigurable optical networks for ML workloads, optical WAN optimization, and satellite Internet connectivity.

In summer 2026, I interned at Microsoft Research's Gray Systems Lab with Dr. Rathijit Sen. Before joining Cornell, I was a Research Fellow at Microsoft Research with Dr. Venkat Padmanabhan, working on network performance and WAN costs for Microsoft Teams.
