I am an Assistant Professor of Computer Science in the School of Computing and Information at the University of Pittsburgh. My primary research interests are in the fields of Natural Language Processing and Cognitive Science, with broader interests in Computational Social Sciences. I work towards building human-level artificial intelligent entities that can work with humans on a broad range of problems using a wide variety of methods, knowledge, and learning techniques.
The focus of my recent works has been on modeling the social and situated context of humans' multimodal communication (including image–text presentations, sign languages, gestures, and diagrams) and designing systems that can naturally and efficiently communicate with users. This involves developing techniques for studying coordination, persuasion, trust, and equity in human-human and human-machine communication.
I completed my Ph.D. in the Department of Computer Science and earned a graduate certificate in Cognitive Science at Rutgers University under the supervision of Prof. Matthew Stone.
Discourse and Dialogue
Learning inferences in text and multimodal discourse; modeling coordination, grounding, and generation in dialogue
Sign Language Processing
Sign language understanding and generation; designing interactive AI systems for signers with applications in healthcare and education.
Domain Adaptation in NLP
Studying generalization and robustness of NLP models using the tools of learning theory; designing theoretical machine learning frameworks for NLP tasks such as language generation and dialogue management
Inclusive NLP for Positive Impact
AI-assisted moderation and mediation; harm measurement, and ethics of social interactions with AI; oppressive practices & norms; pragmatics of harmful speech
