I am an Assistant Professor at CSE, College of Computing at Georgia Institute of Technology. I direct the CLAWS Data Science research group. I create data science and machine learning solutions to solve problems pertaining to the web and the society. Applications include include social media, health, and security. I have pioneered the development of platform integrity algorithms that are being used in production at Flipkart (India's largest e-commerce platform).
My research interests are in web and social media (e.g., misinformation, hate, fraud), trustworthy AI, multimodal data, recommender systems, graphs.
Postdoc opening. There is an opening for one postdoc in my group, who will get to work on very exciting problems in recommendation systems and/or graphs.
