:wave: Hello, I am Sachin Grover, thank you for stopping by!

I am a research scientist at PARC, part of SRI International. My research interests are in LLM based agents, and combining planning and learning techniques/systems. At PARC, I was part of several DARPA projects – SAIL-ON (open-world AI agents), KMASS (knowledge management) and EMHAT (human-ai multi-agent collaboration teams). Previously, I have also worked as an applied scientist intern at Amazon Alexa research on language model quantization and compression techniques.

My Ph.D. was oriented towards designing Human-Aware AI techniques using Automated Task Planning for collaboration in Human-Robot teams and was advised by Prof. Subbarao Kambhampati.

I did my Masters at Arizona State University, advised by Prof. Kurt VanLehn, on modeling student’s knowledge while working on Intelligent Tutoring System.

:point_right: Currently, I am looking for full-time opportunities in research and engineering roles.

Research

My research focuses on designing human-aware techniques and systems utilizing recent improvements in LLMs, planning techniques, and other learning methods. I am also interested in solving real-world complex problems and creating interpretable systems that provide explanations with guarantees utilizing machine learning and AI-planning techniques. My work in the past has been published in refereed journals (AIJ, HCI, IEEE, Taylor & Francis, etc.) and several peer-reviewed conferences (International Conference of Automated Planning and Scheduling ICAPS, Human-Robot Interaction HRI, AI & Education AIED, Naturalistic Decision Making NDM, etc.) and workshops (Knowledge Engineering for Planning and Scheduling ICAPS KEPS, Explainability and AI ICAPS XAIP, ML for Public Health NEURIPS MLPH), etc. A list of my publications can be checked below.
