I love decision making — currently exploring that through intelligent agents and robots using policies. I'm also interested in cognitive science, and am currently a research assistant at the Carney Institute of Brain Sciences at Brown. I love working at the intersection of minds and machines.
my work
Autonomous City Mapping with Multi-Agent Active SLAM
Three RL agents with Mamba state-space memory collaboratively build a real-time city map from raw sensor data alone, achieving 90%+ coverage on real-world street grids.
Hindsight-Driven Self-Improvement for Robot Manipulation
Iterative policy improvement through hindsight-relabelled self-rollouts on goal-conditioned manipulation tasks.
Zero-Shot 3D Affordance Mapping
Language-driven affordance localization in 3D point clouds. CLIP × geometry priors — no training data required.
Latent Stress Dynamics in Sleep
Computational study of HRV-derived stress states and sleep architecture across 8 months of longitudinal wearable data. Accepted at CCN 2026.
I read, play 4 instruments, write poetry, do debates and public speaking, run an NGO in India, and go to the gym. Looking to work with a small and passionate team!
