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...
