I am passionate about using AI and Machine Learning to create intelligent user experiences that connect people to information. I am Principal Research Manager at Microsoft Research AI where I lead the Language and Information Technologies team. The team focuses on enabling machines to understand and communicate in natural language, answer complex questions, assist with task completion and understand how people interact with information. We push the state-of-the-art in several areas while also making impact on real-world problems by transferring and shipping technologies into several products such as Bing, Cortana, Office 365, and Dynamics 365.
My research interests are at the intersection of machine learning, natural language processing, and information access. My earlier work spanned several topics including information extraction, sentiment analysis and understanding, measuring and improving Web search systems. More recently, my research focuses on creating scalable machine learning models for NLP, learning from user interactions and building natural language interfaces to services and data. Before joining Microsoft Research, I received my Ph.D. from the department of Computer Science and Engineering at the University of Michigan Ann Arbor. I also spent sometime working at IBM focusing on several information extraction related efforts. I published 80+ peer-reviewed papers and I am an inventor on 25 (granted and pending) patents.
