Meet Our Team

Experienced leadership and technical teams you can trust.

PSG’s trusted leadership and expert technical teams have over 300 years’ collective experience in ISR analytics and data science, complex system-of-systems engineering, modeling and simulation, machine learning and automated image exploitation. 

Joseph Marvin – President & Founder

As PSG founder and president, Joe focuses the company on combining core competencies with research initiatives in a defined technology roadmap. His background includes service in the United States Air Force as a research and development engineer, and defense industry chief systems engineer and program manager on major system acquisition programs. He applies his experience with product development and delivery to market of large software development baselines to the PSG research agenda. His expertise in space systems, space to ground interfaces, and ground processing of satellite data is built on career experiences with space systems in both the government and industry.

Joe’s interest in systems engineering of complex systems has led the PSG research agenda toward autonomous systems, complex adaptive systems and robotics decision support systems. This research thrust resulted in Small Business Innovation Research (SBIR) innovative research awards with the Department of Defense and Department of Energy. Under Joe’s leadership, PSG has forged research relationships with Arizona State University’s Sensors, Signals and Information Processing (SenSIP) industry consortium. This relationship is driving collaborative research in machine learning and artificial intelligence. He has published several technical papers on complex systems, modeling and simulation and systems engineering process maturity.

He entered the Air Force through the Arizona State University R.O.T.C. program and returned to Arizona after service with wife, Sharon, and children, Jared and Megan. He is a member of the International Council of Systems Engineers (INCOSE), and serves as a certified expert of systems engineering. He is also the Arizona State president of the Air Force Association. Joe received his BS in engineering science from Arizona State University and his MS in engineering science from Northrup University in Los Angeles, California.
