DR. DAVID M. CUMMINGS

Dr. Cummings has over thirty-five years of experience as a software architect, engineering manager and consultant in technology areas including fault-tolerant computing, operating systems, networking, parallel and distributed systems, computer architecture, wireless communications, satellite communications, real-time embedded systems, spacecraft systems, automotive systems, hardware/software integration, storage area networking, backup/recovery, disaster recovery, transaction processing, database management and file systems. He has extensive hands-on experience in project management and the entire product development lifecycle, from initial product conception through requirements definition, design, implementation, test, deployment and support. Dr. Cummings also has significant experience as a technical expert in matters involving computer and smartphone forensics, patent infringement, trade secret misappropriation, and copyright infringement. He has testified at deposition and in court.

Dr. Cummings has built and managed world-class engineering teams and developed complex systems for large and small organizations, including Brocade Communications Systems, NASA's Jet Propulsion Laboratory, the Federal Aviation Administration, Teledyne, ComTier (a startup acquired by Andrew Corporation), and Wireless, Inc. (a startup acquired by interWAVE/Alvarion). At the Jet Propulsion Laboratory, where he served as a consultant for over nine years, Dr. Cummings architected and developed a significant portion of the software for the Mars Pathfinder spacecraft, which successfully deployed the first rover on the surface of Mars in 1997. Just prior to joining KTG, Dr. Cummings was the Vice President of Engineering for Asempra Technologies in Silicon Valley (a startup acquired by BakBone/Quest/Dell). At Asempra, Dr. Cummings assembled a global team of engineers in the U.S., Russia and Ukraine and led that team in the development of a novel approach to backup, recovery and disaster recovery using continuous data protection.

Dr. Cummings has received numerous technical and managerial awards, including two NASA awards for his contributions to the Mars Pathfinder spacecraft, and an FAA award for on-time delivery with extremely high quality. Under his engineering leadership, Asempra Technologies was recognized within the storage industry as one of the top 10 startups of 2006.

Dr. Cummings was retained as a testifying expert for the defense in the U.S. Department of Justice's criminal prosecution of former BP employee Kurt Mix after the Deepwater Horizon oil spill. On behalf of Mr. Mix, Dr. Cummings performed extensive forensic analysis and recovery of deleted text messages, voicemail messages, photos, and data files from iPhones belonging to Mr. Mix and others.
