I am a research scientist at Vanderbilt University, USA. My research interests include multi-agent systems, robust machine learning, and decision-making under uncertainty. I am honored to be one of the recipients of the Google AI Impact Scholar Award (2021) for Social Good.
Prior to this, I was a Post-Doctoral Research Fellow at the Stanford Intelligent Systems Lab at Stanford University, USA, working under Prof. Mykel Kochenderfer. I was awarded the 2019 CARS post-doctoral fellowship by the Center of Automotive Research at Stanford (CARS). Before joining Stanford, I was a Ph.D. student at Vanderbilt University’s Computational Economics Research Lab under Prof. Eugene Vorobeychik. My thesis was nominated for the Victor Lesser Distinguished Dissertation Award 2020.
I am particularly interested in applying AI to real-world problems, especially ones that have societal impacts. Much of my dissertation focussed on using AI to aid proactive emergency response. My current work focuses on designing decentralized decision-making systems for emergency response, understanding how crowdsourced reports can be used to infer emergency scenarios, optimizing para-transit routing, trying to understand how to tackle wildfires and heatwaves, and designing deep learning methods for aiding conservation. At Stanford, I was one of the mentors for Stanford’s CS+Social Good Impact Lab, helping undergraduate students use AI for social good. My research is supported by Cisco, National Science Foundation, Google AI for Social Good, and Microsoft AI for Earth.
If you are interested in these research areas or want to explore AI for social good, feel free to reach out. I am happy to chat, learn, help, and collaborate!
- Our paper on using AI for optimizing vaccination uptake in Nigeria won the best paper award at the International Joint Conference on Artificial Intelligence (IJCAI 22, social good track). To know more, check out my interview on the INFORMS Resoundingly Human podcast or take a look at the paper here.
- We had two papers accepted at IJCAI 22. In collaboration with HelpMum and Google, we developed ADVISER: AI-Driven Vaccination Intervention Optimiser for increasing vaccination uptake in Nigeria. Also, in collaboration with Aron Laszka's group at UHouston, we explored a novel formulation for the vehicle routing problem with applications to paratransit. Our formulation looked at the offline vehicle routing problem with online bookings.
