Hi! I'm currently in Carnegie Mellon's MRSD program, where I've gone from someone who worked in classical robotics to someone who now "teaches" robots how to do things.

This past summer, I interned at Bosch Center for AI, where I looked into failure modes in VLAs and hallucination in world models.

My work sits at the intersection of research and deployment, which allows me to reason through the "why" behind a system's behavior while staying grounded in what it actually takes to build and ship one. The result is creative and well-reasoned solutions.

Outside of robots, I read, travel, watch pretty much any movie, and love geeking out over how humans think.

Improving Policy Training for Manipulation tasks using World Models
Dexterous Transfer: Arms to Humanoids

We're building a mobile manipulator to automate labor-intensive tasks in lab environments.

On the technical side, I worked on the autonomous navigation stack. We used a 3D LiDAR with FAST-LIO for SLAM and localization.

Ground truth v/s world model hallucinated data

  • 3D SLAM

  • Indoor Navigation

  • Sensor Fusion

  • LiDAR-Intertial Odometry

  • VLA

  • World Models

  • Robot Learning

  • RL PPO

  • Isaac Lab

  • Hierarchical planning

We evaluate whether data generated by world models, despite being visually bad, can still be utilized for policy training and suggest a new training objective for World Models.

Explored object-centric hierarchical planning for bi-manual dexterous manipulation on fixed arms.

We used MoCap data for the high-level wrist motion-planner and used RL finetuning for the contact-rich physics (low level planner).

Further extended the policy onto Unitree G1 humanoid.

DPSO-Q: A Reinforcement Learning–Enhanced Swarm Algorithm for Solving the Traveling Salesman Problem

DPSO-Q blends particle swarm optimization with Q-learning to solve the classic Traveling Salesman Problem more efficiently. It cuts route lengths by up to 7.5% over standard swarm methods and runs over 90% faster than ant-colony approaches.
