Saubhagya Joshi
PhD Student · Rutgers University · SC&I
I am a PhD student in Library & Information Science at Rutgers University (2024 cohort), where I study the robustness of large language models in healthcare informatics and the trustworthiness of human-centered AI systems. My work sits at the intersection of responsible AI, health information behavior, and cross-language robustness in generative AI.
I hold a Master of Information (Data Science) from Rutgers and a Master of Engineering (Information Management) from AIT, Bangkok. Before returning to academia I spent over a decade in systems support, mobile application development, and university teaching across three continents.
I am best reached by email at sau.joshi@rutgers.edu.
