Bio

I am a 3rd year Computer Science PhD student at Georgia Tech, advised by Dhruv Batra, and working closely with Devi Parikh. My research focuses on deep learning and its applications in building agents that can see (computer vision), think (reasoning/interpretability), talk (language modeling), and act (reinforcement learning).

My research is supported by fellowships from Facebook, Adobe, and Snap. My CV is available here.

I’ve spent three wonderful semesters as an intern at Facebook AI Research — Summer 2017 and Spring 2018 at Menlo Park, working with Georgia Gkioxari, Devi Parikh and Dhruv Batra on training embodied agents for navigation and question-answering in simulated environments (see embodiedqa.org), and Summer 2018 at Montréal, working with Mike Rabbat and Joelle Pineau on emergent communication protocols in large-scale multi-agent reinforcement learning.

In 2019, I was fortunate to get the opportunity to spend time at DeepMind in London working on grounded language learning with Felix Hill, Laura Rimell, and Stephen Clark, and at Tesla Autopilot in Palo Alto working on differentiable neural architecture search with Andrej Karpathy.

Prior to joining grad school, I worked on neural coding in zebrafish tectum as an intern under Prof. Geoffrey Goodhill and Lilach Avitan at the Goodhill Lab, Queensland Brain Institute.

I graduated from Indian Institute of Technology Roorkee in 2015. During my undergrad years, I’ve been selected twice for Google Summer of Code (2013 and 2014), won several hackathons and security contests (Yahoo! HackU!, Microsoft Code.Fun.Do., Deloitte CCTC 2013 and 2014), and been an active member of SDSLabs.

On the side, I built neural-vqa, an efficient Torch implementation for visual question answering (and its extension neural-vqa-attention), and maintain aideadlin.es (countdowns to a bunch of CV/NLP/ML/AI conference deadlines), and several other side projects (HackFlowy, graf, etc). I also help maintain Erdős, a competitive math learning platform I created during my undergrad. I often tweet, and post pictures from my travels on Instagram and Tumblr.
