Bio
I am a Research Scientist at Fundamental AI Research (FAIR) at Meta working on deep neural networks and its applications in climate change. My current focus is on electrocatalyst discovery for renewable energy storage as part of the Open Catalyst Project. Renewable energy sources (like solar, wind) are great but intermittent – the sun shines only during the day. During the evening, we fall back on fossil fuels. To avoid this, we need to discover cheap, scalable ways of converting electricity from renewable sources to storable forms, so that we can transfer it from times of peak generation to peak demand. AI can help accelerate the chemical simulations needed to make these discoveries.
Before this, I was a Computer Science PhD student at Georgia Tech, advised by Dhruv Batra, and working closely with Devi Parikh, where I focused on developing artificial agents that can see (computer vision), talk (language modeling), and act (reinforcement learning).

During my PhD, I interned thrice 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 communication protocols in multi-agent reinforcement learning. In 2019, I interned 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.
My PhD research was supported by fellowships from Facebook, Adobe, and Snap.
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 got my Bachelor’s at IIT Roorkee in 2015. During my undergrad, I took part in Google Summer of Code (2013 and 2014), won several competitions (Yahoo! HackU!, Microsoft Code.Fun.Do., Deloitte CCTC 2013 and 2014), and owe most of my programming/tinkering bent to SDSLabs.
On the side, I built aideadlin.es (countdowns to a bunch of CV/NLP/ML/AI conference deadlines) and aipaygrad.es (statistics of industry job offers in AI), neural-vqa and its extension neural-vqa-attention, HackFlowy, graf, Erdős, etc. I also occasionally dabble in generative art. I like this map tracking the places I’ve been to. Blog posts from a previous life.

Talks
Side projects
aipaygrad.es
aipaygrad.es provides statistics of industry job offers in Artificial Intelligence (AI).
All data is anonymous, cross-verified against offer letters and will
hopefully reduce information asymmetry.
aideadlin.es
aideadlin.es is a webpage to keep track of CV/NLP/ML/AI conference deadlines. It's hosted on GitHub, and countdowns are automatically updated via pull requests to the data file in the repo.
neural-vqa-attention
Torch implementation of an attention-based visual question answering model (Yang et al., CVPR16).
The model looks at an image, reads a question, and comes up with an answer to the question and a heatmap of where it looked in the image to answer it.
Some results here.
neural-vqa
neural-vqa is an efficient, GPU-based Torch implementation of the visual question answering model from the NIPS 2015 paper 'Exploring Models and Data for Image Question Answering' by Ren et al.
Erdős
Erdős by SDSLabs is a competitive math learning platform, similar in spirit to Project Euler, albeit more feature-packed (support for holding competitions, has a social layer) and prettier.
graf
graf plots pretty git contribution bar graphs in the terminal.
gem install graf to install.
HackFlowy
Clone of WorkFlowy.com, a beautiful, list-based note-taking website that has a 500-item monthly limit on the free tier :-(. This project is an open-source clone of WorkFlowy. "Make lists. Not war." :-)
AirMaps
AirMaps was a fun hackathon project that lets users navigate through Google Earth with gestures and speech commands using a Kinect sensor. It was the winning entry in Microsoft Code.Fun.Do.
HackView
Another fun hackathon-winning project built during Yahoo! HackU! 2012 that involves webRTC-based P2P video chat, and was faster than any other video chat provider (at the time, before Google launched Hangouts).
8tracks-downloader
Ugly-looking, but super-effective bash script for downloading entire playlists from 8tracks. (Still works as of 10/2016).
