About Me

I am a PhD candidate in Computer Science at Rutgers University, New Brunswick. I am fortunate to have S. Muthukrishnan as my advisor. I am also co-advised by Yongfeng Zhang and work closely with Gerard de Melo.

I have successfully defended my thesis and will join Amazon Ads as an Applied Scientist.

My research interests lie in the interface of Machine Learning and Information Retrieval with specific focus on

  • Machine Learning: Graph Representation Learning, Knowledge Graph Reasoning, Neural Symbolic Reasoning, Deep Reinforcement Learning
  • Information Retrieval: Explainable Recommendation, Conversational Recommendation, User Behavior Modeling, Schema Matching
