Here is my resume


I am a third-year PhD student in Computer Science at RPI. I am currently working on social choice (rank aggregation) problems with Professor Lirong Xia.


Rank aggregation problems have a wide range of applications, including presidential elections, yelp rating, college ranking, and so on. People (agents) have diverse preferences over the alternatives (presidential candidates, restaurants, etc.) even though there is a ground truth. Ranking models are used to model this uncertainty. My research focuses on efficient estimation of ground truth parameters of ranking models, mainly from the computational perspective. Specifically, I am interested in identifiability of a class of ranking models, the convergence rate of an algorithm, and the statistical accuracy.
