Sam Moradzadeh

I am a Ph.D. candidate in Informatics at Pennsylvania State University, working in the Wellbeing & Health Innovation Lab. Prior to my Ph.D., I earned my Master of Science degree in Computational Design at Penn State, and have conducted human-centered AI and behavioral analytics research across government and enterprise labs, including the Laboratory for Analytic Sciences and Willis Towers Watson.

My research lies at the intersection of Human-Computer Interaction (HCI), Large Language Models (LLMs), and Decision-Support Systems, with a strong focus on digital health and high-stakes professional workflows. I investigate how the design of computational systems shapes human agency, oversight, and collaborative reasoning. Across my work, I develop, engineer, and evaluate AI-powered interactive systems—integrating RAG pipelines, multi-mode AI agents, and behavioral telemetry logging with formative and longitudinal human studies—to build trustworthy AI collaborators that augment rather than replace human expertise.
