Sarthak Chittawar

I am a graduate researcher at the Robotics Research Centre (RRC), IIIT Hyderabad, working at the intersection of mobile robotics, computer vision, and machine learning. My research focuses on visually grounded navigation, topological mapping, embodied AI, and relative 3D representations that enable robots to operate robustly in large-scale real-world environments.

I am pursuing a B.Tech + M.S. by Research in Computer Science and Engineering at the International Institute of Information Technology, Hyderabad, under the supervision of Prof. K. Madhava Krishna. My recent work includes MASt3R-guided topological navigation, pixel-level loop closures for shortcut navigation, and object-centric visual localization.

Starting Fall 2026, I will be joining IBM Research as a Research Engineer, where I look forward to working on cutting-edge problems in AI, machine learning, and intelligent systems.
