Experience

Postgrad Researcher

AI-NLP-ML Research Lab | IIT Patna

•Sep 2024 - Present

Led NLP healthcare research under Dr. Sriparna Saha, developing a framework that reduced hallucinations in AI-generated radiology impressions by 45%. Implemented and optimized advanced RL techniques (DPO, PPO, RLOO). Trained 3 specialized reward models that enhanced safety compliance and factual accuracy. Analyzed 10,000+ radiology reports to enhance impression generation.

Data Scientist

Omnissa (formerly VMware EUC)

•Jul 2025 - Dec 2025

Built a natural language driven workflow generator using a multi-agent LangGraph architecture that decomposes queries, resolves resources identifiers via APIs, and constructs UEM workflows from user intent. Integrated with Freestyle Orchestrator, Omni Chat, and VMA Agent to support automated workflow building and deployment. Built a robust testing framework to ensure reliability and scalability.
