I am current a Visiting Research Scientist at Google. From Jan 2020, I will be an Assistant Professor at the College of Computing, Georgia Institute of Technology. My research lies in data science and applied machine learning on web-scale online social systems. I have pioneered the development of trust, safety, and well-being algorithms that are being used in production at Flipkart (India's largest e-commerce platform) and are being deployed at Wikipedia. I am the recipient of the 2018 ACM SIGKDD Doctoral Dissertation Award runner-up, WWW 2017 Best Paper Award runner-up, Larry S. Davis Doctoral Dissertation Award 2017, and Dr. BC Roy Gold Medal.
My current research thrusts include:
Multiple openings for Ph.D., masters, and undergraduate students. If you are super motivated and want to work on high-impact problems, send me an email with your interests and CV. No visiting students, sorry.
