I am a board-certified internal medicine physician and academic hospitalist at Stanford University with national expertise in adult inpatient standards of care, diagnostic reasoning, and hospital systems. I have been practicing hospital medicine at Stanford for a decade, where I have several leadership roles related to teaching junior physicians and medical students. I currently serve as the Director of Clinical Reasoning at Stanford University School of Medicine. As a faculty member with a Master's in Education who has received over 25 teaching awards over my career, I aim to provide clear communication of complex medical issues to legal teams, clients, and juries. I have greater than 5 years experience reviewing medical negligence cases involving hospitalized adults for both plaintiffs and defenses. I am a recognized expert in clinical decision-making and failure to recognize or treat scenarios among hospitalized adults seen in urgent care, emergency department, acute care, and cr...

I am a Distinguished Professor of Computer Science at the University of Florida, IEEE Fellow, and AAAS Fellow, and I serve as an expert witness in patent litigation and other complex technology matters involving distributed systems, cloud infrastructure, data platforms, machine learning, GPU-accelerated and high-performance computing systems, and large-scale software architectures. My work focuses on helping counsel and courts understand how modern computing systems operate in practice—particularly where technical claims, system behavior, and real-world implementation diverge. This includes analyzing how systems behave under scale, latency, partial failure, and distributed coordination constraints. I provide clear, structured, and defensible technical analysis across all phases of litigation, including expert reports, depositions, PTAB/IPR proceedings, and trial testimony. I previously served as CTO and co-founder of Paramark, an ad-serving optimization platform (PILOT) that opera...
