Experience

1. Principal Applied Scientist

   Oracle

   Feb 2025 — Present

   Note-Eval Platform (LLM Evaluation & Reliability): Led the design and deployment of a scalable evaluation platform for clinical LLM systems, converting subjective, manual review workflows into a structured, data-driven evaluation framework. Defined the end-to-end architecture for aligning generated outputs with ground-truth physician notes, enabling rigorous, fine-grained assessment of model behavior across clinical contexts.Architected sentence- and section-level alignment pipelines and a hierarchical taxonomy for change classification (e.g, omissions, hallucinations, stylistic edits), improving interpretability and trust in model outputs. Integrated embedding-based similarity, LLM-driven classification, and evidence grounding to ensure high precision and robustness.Scaled the system to support large-scale batch processing with parallel execution, fault tolerance, and comprehensive evaluation metrics (precision/recall/F1), significantly reducing false positives and improving model validation quality.Drove cross-functional impact by partnering with clinicians, product, and engineering teams to operationalize evaluation insights, influence model iteration strategies, and establish best practices for LLM reliability in high-stakes environments.
