About Me

I completed my high school in 2013 at a school in Chennai. I spent the next 4 years in the BTech program at the Computer Science & Engineering Department at IIT-Madras, working on Machine learning and Computer Graphics research.

Until August 2019, I'm a Research Assisstant at the Computer Graphics Group at CMU under Prof. Ioannis Gkioulekas, working on shape reconstruction and appearance acquisition through differentiable rendering.

Starting Fall 2019, I will be a PhD student at MIT CSAIL, supported by a 1 year incoming fellowship.

In my time-off, I like to travel, take pictures, and design websites. The end of this webpage has a few of my favourite pictures.

Research Projects

Selected projects from 2013 through 2019

Parallel Algorithms

CUDA-Scotty

A performance-optimized CUDA path tracer that uses dynamic ray scheduling and 8-way BVH trees in order to make maximum use of the GPU's architecture. The algorithm used is based on a breadth-frist traversal where all the rays are advanced through the BVH one level at a time.

Physics-based Vision

Inverting generalised Global Illumination

A solution to the problems with shape-recovery methods. Uses a mitsuba shape-differentiable path tracer and a TensorFlow optimizer to obtain accurate reconstructions in the presence of interreflections and non-lambertian surfaces.

Deep Scene Representations

Action Conditional Projection Neural Networks

Similar to Action-Conditional Video Prediction, which predicts the next frame of an ATARI game given the user input, ACPNNs are designed to predict 2D and 3D environments where the output is based on perspective vision.

Deep Reinforcement Learning

Multi-task Reinforcement Learning

Exploration in multi-task reinforcement learning is critical in training agents to deduce the underlying MDP. We present a novel method to facilitate exploration in multi-task reinforcement learning using deep generative models. We evaluate our method on a new set of environments and provide intuitive interpretation of our results.
