Hi!

I am a Senior AI Research Scientist at Intel AI (erst. Intel Labs, USA), where I currently lead and contribute to various projects spanning Large Language Models (LLMs), Continual Learning, Out-of-Distribution (OOD) detection, Human-in-the-Loop (HITL) Learning, Retrieval-Augmented Generation (RAG), LLM Domain-Adaptation and Post-training, LLM Safety and Agentic AI. My research primarily focuses on developing models, intelligent systems and agents that can recognize the unknown, learn and adapt continuously after deployment, and act safely and responsibly in the open-world. Broadly, my research interests lie at the intersection of - Natural Language Processing (NLP), Deep Learning, Lifelong and Continual Learning, Open-World AI / Learning, Conversational AI / Human-AI Interaction, and Trustworthy and Safe AI .

Prior to joining Intel, I earned my PhD in Computer Science at the University of Illinois at Chicago (UIC), USA under the supervision of Prof. Bing Liu, where I began working on Continual Learning for Dialogue and Interactive Systems and was among the early contributors to research this topic, focusing on developing chatbots capable of continuously acquiring factual knowledge, reason over newly learned information, and adapting through post-deployment interactions. Along with my PhD advisor, I also co-authored - Lifelong and Continual Learning Dialogue Systems (Springer Nature, 2024), the first-ever book on this topic. I have authored 30+ research publications, filed 3 patents (including one granted) and delivered tutorials at leading AI, NLP, and dialogue conferences and have been serving as an Area Chair for ACL Rolling Review (ARR) and as a PC Member / Reviewer of various premier AI / ML / NLP conferences and journals. During my PhD, I also worked as a Summer Research Intern at Microsoft Research - Redmond on building natural language interface for Web and UI navigation and at Futurewei Technologies (aka Huawei Research USA) on Multi-task Lifelong Learning on Personal Device for Improving User Experience. I also received the prestigious Peter and Deborah Wexler Graduate Student Award during my PhD at UIC.

Before joining UIC, I received my Masters in Computer Science from Indian Institute of Technology (IIT) - Roorkee, India under the supervision of Dr. Dhaval Patel (presently, at IBM TJ Watson Research Lab, NY) and Bachelor in Computer Science from Indian Institute of Engineering Science and Technology (IIEST) - Shibpur, India. After my Masters and before joining PhD, I also worked as a Junior Research Fellow at IIT Roorkee, contributing to research projects on news data analytics and location-aware review mining.
