Director
The main goal of my research is to dramatically increase our ability to mine actionable knowledge from unstructured text. I am especially interested in information extraction from the Web, understanding the connections between people and between organizations, expert finding, social network analysis, and mining the scientific literature & community. Toward this end my group develops and employs various methods in statistical machine learning, natural language processing, information retrieval and data mining---tending toward probabilistic approaches and graphical models.
PhD Students
Neha Kennard (started 2018)
My research interests are in Natural Language Processing. At the moment, I am working on understanding document-level discourse structure

Now a research scientist at Amazon
Dhruvesh Patel (started 2021)
Interested in scaling principled non-autoregessive generative models like discrete diffusion and flows for text generation
Wenlong Zhao (started 2021)
My current research involves structured prediction and representation learning for natural language. I also work on efficient deep learning, computer vision, and interdisciplinary applications of algorithms, such as, AI for sustainability.
Benjamin Rozonoyer (started 2022)
I am interested in theoretical machine learning and natural language processing, including semantic parsing and information extraction.
Dhruv Agarwal (started 2022)
My broad research interest is in machine learning for natural language processing and its application in tasks that require complex, multi-step reasoning. My current focus is on interactive machine learning to probabilistically incorporate human-provided constraints and feedback.
