I am a Ph.D. Candidate in Computer Science at Cornell University in Ithaca, NY. I am advised by Thorsten Joachims. I am fortunate to have Solon Barocas, Karthik Sridharan, and David Mimno on my dissertation committee.

My research spans the broad areas of Machine Learning, Recommender Systems, and Information Retrieval. My research focuses on:

  • Building machine learning models and algorithms to learn from interactive user feedback in user-facing platforms such as search and recommendation.
  • Fairness and Responsibility aspects of Recommender Systems considering fair distribution of opportunity for both users as well as the items.

Through my research, I envision search and recommendation systems to form the foundation of economically sustainable multistakeholder online platforms that ensure utility, fairness, and safety for the users as well as the creators and producers.

During my Ph.D., I have completed internships at Google Brain, Facebook Research, and Microsoft Research (NYC and Montreal) where I had the opportunity to collaborate closely with Alex Beutel, Fernando Diaz, Khalid El-Arini, John Langford. Previously, I was an undergraduate student at the Indian Institute of Technology (IIT) Kanpur and also spent a summer at Carnegie Mellon University doing research on Natural Language Processing.
