EXPERT WITNESS

I have extensive experience as a patent expert witness, having authored numerous expert reports, participated in multiple depositions, supported Markman rulings, and testified in court, including cross-examination before a jury. My involvement encompasses patent reexaminations and appearances at the USPTO, providing expert analysis in inter partes reviews and complex litigation cases. This practical expertise in patent claims, infringement analysis, and technology evaluation is supported by a strong track record of collaborating with prominent legal teams in high-stakes intellectual property disputes.

Academically, I am a Distinguished Professor of Computer Science at the University of Florida, focusing on data structures, applied algorithms, machine learning, artificial intelligence, and cloud computing. I have published over 350 journal and conference articles, coauthored books and monographs, and serve as an associate editor for several leading journals in computing and informatics. My professional recognition includes fellowships with IEEE, AAAS, and AIAA, as well as awards for research impact and distinguished alumni achievements, highlighting my leadership in the computing research community.

In industry, I served as Chief Technology Officer at Paramark, where I developed the PILOT system, a real-time optimization service for marketing campaign targeting that integrated data from multiple sources. Paramark was a recognized leader in internet technology before its acquisition, reflecting my ability to translate advanced research into commercially successful innovations. I have co-invented over 10 patents in computer science, directly contributing to advancements in message optimization, advertising inventory management, and network bandwidth scheduling, often drafting key patent claims myself.
