I am a PhD. student in the Department of Computer Science at Purdue University. My research interests are in the areas of Natural Language Processing and Machine Learning. Particularly in highly structured problems that require complex inferences. My work focuses on combining deep learning and declarative inference for conversational and relational domains. I am currently working with Professor Dan Goldwasser as part of the Purdue NLP Group.
