I am a MS/PhD student in computer science at the University of Massachusetts Amherst advised by Professor Andrew McCallum. I am a member of the Information Extraction and Synthesis Laboratory. My research focuses on machine learning and natural language processing. I received my B.S. in computer science and mathematics from Brandeis University in 2013 where I worked with Professors James Storer and Antonella Di Lillo.
The focus of my research is scalable clustering methods with an application focus on entity resolution. In particular, developing clustering methods that scale to massive numbers of clusters (entities) and points (entity mentions). I am also interested in extending these methods to model dependencies between the cluster (entity) assignments of points (mentions). My research includes models to learn robust entity representations, in particular modeling mention spellings. I am interested in the combination of entity linking and resolution, a problem setting where we are given an initial knowledge base and discover new entities as more data arrives.
