About Me

I am a Computer Scientist at the Center for Vision Technologies at SRI International, where I primarily work with Ajay Divakaran, Yi Yao and Giedrius Burachas on applying Deep Learning to Computer Vision and Natural Language Processing tasks. I finished graduate school (Master's) majoring in Computer Engineering from Virginia Tech (VT). While at VT, I had the honor of working in the Computer Vision Lab advised by Prof. Devi Parikh and in close collaboration with Prof. Dhruv Batra.

In my research, I am excited about how to make human-AI and AI-AI teams solve tasks effectively. Currently, I am doing so by training machines to understand how the semantics of vision and language intertwine with each other. I believe this is a crucial step for AI's to be able to act effectively in a human-AI or AI-AI collaborative environment.

Life Highlights:

  • 2019: Our work on evaluating machine explanation helpfulness in Visual Question Answering settings got featured by the online Science and Tech magazine, TechXplore (phys.org)! Come check out our demo at CVPR2019 on Jun 18! [link]
  • 2019: I won a grant at the SRI CVT Shark Tank Competition that will support my project on using AI to reduce radicalization of opinions on social media. Please contact me if you are interested in a summer internship opportunity
  • 2017: I hosted the annual SRI CVT Lab Day Team Challenge with a human-AI collaborative image-retrieval game with AI's that can "rationalize/explain" their decisions to humans!
  • 2017: The startup I interned at (Blue River Technologies) got acquired by John Deere for $305 million! The weed detection technology I helped develop played a key part in this process!
  • 2017: I started working at SRI International - Center for Vision Technologies
  • 2017: I graduated from Virginia Tech and successfully defended my thesis!
  • 2016: Paper on VQA Relevance accepted at EMNLP 2016! Title: Question Relevance in VQA: Identifying Non-Visual And False-Premise Questions
  • 2016: Paper on CoNLL Shared Task on Discourse Parsing accepted at CoNLL 2016! We ranked within top 10 worldwide!
  • 2016: I won Employee of the Fortnight award as an intern at Blue River Technology! (now acquired by John Deere, September 2017)
  • 2016: I am interning at a Deep Learning Agri-tech startup called Blue River Technology over the Summer of 16. (Update: Acquired by John Deere as of September 2017)
  • 2016: I will be serving as the Vice President of Tau Beta Pi, Virginia Beta Chapter, from Fall 2016 for a year!
  • 2015: I served as a reviewer for CVPR 2016!
  • 2014: Our Face-recognition UAV for helping locating natural disaster victims featured in National News : Deccan Chronicle, Indian Express etc
  • 2013: I won a silver medal at SRM University Research Day for my white-paper presentation on an Electro-Mechanical Exoskeleton.
  • 2012: I won an Academic Merit Scholarship from SRM University that waives a part of my tuition for excellent academic performance.

Hobbies

When I am not making multi-layer neural networks, you will usually find me playing the guitar (part of the School of Rock, Princeton and SRI's informal music band), or lindy-hop dancing! I love cooking/baking too - I definitely do plan on releasing my custom recipes of fusing cuisines from various cultures online someday. I am the proud inventor of a more interesting (read unhealthier) way to make Ramen Noodles, the recipe of which I will also put up soon. Check back later for more!

As a child, I was always interested in engineering simple gadgets. I opened an informal research society in my middle school to encourage middle schoolers to take an interest in science by engineering simple gadgets like a password machine using logic gates, automatic night lights, a keyboard piano and so on.
