More than just
the research

I grew up in India with two things that never left me — a curiosity for how things move and a pencil in my hand. Before I ever wrote a line of code, I was a freelance artist, making portraits and 3D digital artwork on commission. I served as the Design Head of Yodha — The Warrior Within, a social service organization where I created posters, banners, and visual campaigns.

That creative instinct led me to engineering — first a B.E. in Mechanical Engineering from Visveswaraya Technological University, then across the world to Michigan Tech in Houghton, MI for an M.S. in Mechatronics and now a PhD in Electrical Engineering. Somewhere along that journey, I fell deep into the world of legged robotics and reinforcement learning — teaching machines to walk so that one day, astronauts can walk better on the Moon.

Outside the lab, I'm always chasing something new. Since moving to the U.S., I've picked up skiing, golf, indoor rock climbing, clay sculpting, and I'm a serious 8-ball pool player. Back in India, it was chess, basketball, and cricket. The through-line is simple — I love learning things from scratch, whether it's a new gait controller or a new sport.

VLM-Based Robot Navigation & Cyber-Physical Security
Jun 2025 — Present
Graduate Research Assistant

Built a hierarchical control framework for autonomous object search with the Unitree Go1, integrating VLM-based navigation (Qwen3-32B) with RL locomotion control. Demonstrated the first history-based backdoor attack on LLM-controlled robots with >98% attack success rate while maintaining full utility in benign runs. Achieving 90% task completion in multi-room environments.

Benchmarking MPC vs RL for Legged Locomotion
Jun 2025
Published in IEEE Access 2025 · Presented at IROS

Developed a standardized MuJoCo benchmarking framework for the Unitree Go1. RL recovered 0.25s faster than MPC and achieved 41% lower energy cost, while MPC demonstrated 36% higher lateral stability. Open-source framework supported by NSF.

BT-SLIP: Leg Compliance in Biped Locomotion
2025
Conference Submission · IROS

Proposed a modified planar bipedal trunk spring-loaded inverted pendulum model in MuJoCo with actuated hip and prismatic joints augmented by passive spring-dampers. Trained with RL and validated against human experimental data, then conducted parametric studies on how leg compliance shapes emergent gait patterns across velocities.
