Praphul Singh

Senior Principal Applied Scientist · Oracle Health AI

I work on language models and AI agents, with a particular interest in how they learn, reason, and improve through experience. My research spans agent evolution and self-improvement, reinforcement learning, recurrent and looped models, interpretability, and model editing. I’m drawn to questions that connect new capabilities with a deeper understanding of how models change.

I’m a Senior Principal Applied Scientist at Oracle Health AI, where my current focus is Evolve, a governed platform for the automatic evolution of clinical AI agents. This work brings those research questions into deployed systems, with an emphasis on evaluating improvement and maintaining reliability as agents evolve.

My industry work spans platforms and clinical workflows. I lead Oracle Health’s data de-identification and secure storage platform, supporting millions of clinical notes, alongside clinical audio, across thousands of patients for AI training, analytics, and evaluation. I’ve also designed and built workflows spanning orders, diagnosis association, search, and note generation.

Previously, my work on Oracle OneSearch spanned enterprise search, custom language models, retrieval-augmented generation, document question answering, and SQL analysis. Across my work at Oracle, I have filed 19 U.S. patent applications.

Outside research, I enjoy writing, cricket, singing, and time at the gym. I’m equally drawn to quieter moments in nature, especially an evening spent gazing at the moon.
