I am interested in the field of information retrieval, natural language processing and machine learning. More specifically, I am interested in the study and development of effective and efficient evaluation techniques that help measure how well retrieval systems satisfy user's information needs. I have worked on research problems including evaluation of retrieval and question answering systems, web search, recommendation systems, and dialogue system for healthcare and scheduling.
Prior to joining IBM I was Data Scientist at a startup (X.AI Inc.) building a AI personal assistant that automatically schedules meetings. Previously, I was a Postdoctoral Research Scientist at Columbia University working with Dr. Chunhua Weng at the Biomedical Informatics Department. I was a Research Assistant at the Information Retrieval Lab supervised by Dr. Ben Carterette where I completed my Ph.D. in Computer and Information Science at University of Delaware.
