I hold an MS in Computer Science from the University of Southern California (USC). Before my time at USC, I worked as a Software Developer at Morgan Stanley. I graduated from the Indian Institute of Technology (IIT) Guwahati with a B.Tech in Engineering Physics and a minor in Computer Science and Engineering.

I am currently looking for research positions in robotics.

Projects

Controller for Unitree A1 Quadruped Robot GitHub

Designed controllers for Unitree A1 quadruped robot in MATLAB Simscape to perform walking, turning, running, stair climbing and obstacle avoidance. Developed and implemented QP and MPC controllers, trotting gait sequence, a linear trajectory for walking, a cycloid trajectory for running and a 5th-order polynomial trajectory for stair climbing.

Masked Autoencoders for Adversarial Purification GitHub

Designed and implemented an adversarial image purification model using fine-tuned Masked Autoencoders (MAEs) to restore perturbed images to their original form, rendering adversarial attacks ineffective. Conducted experiments on the ImageNet dataset to mitigate adversarial attacks generated by Gaussian noise and the Fast Gradient Sign Method (FGSM).

Analysis of Surface Names for entities in Wikipedia GitHub

Analyzed the characteristics of incorrectly mapped links in Wikipedia pages and explored solutions to correct them. Created a novel dataset to aid in further research to provide contextual information of errors.
