Greg Wyss

Cyber Systems Security R&D

Gregory Wyss has worked in the areas of risk, reliability, and vulnerability assessment at Sandia National Laboratories for almost 35 years.  During that time, he has performed risk assessment studies for nuclear reactors, space vehicle launches, nuclear test facilities, telecommunications facilities, and a variety of other high-integrity and potentially high-consequence systems.  He has also developed risk and vulnerability assessment and uncertainty analysis methodologies for a broad range of applications.  He has expertise in the areas of security vulnerability analysis and risk analysis, safety risk assessment for space nuclear systems, system-theoretic process analysis, system-of-systems studies, fault tree analysis, event tree analysis, and integrated risk uncertainty analysis using Latin hypercube sampling and other techniques. He has taught short courses on these subjects for more than 30 years.

Greg has responsibilities that include development of enterprise security risk management methodologies for high-security nuclear facilities.  He has also supported the Interagency Nuclear Safety Review Panel (INSRP) in its review and assessment of risks for the launch of the Pluto New Horizons, Mars Science Laboratory (“Curiosity”), and Mars 2020 (“Perseverance”) space missions.  His research interests include assessment of microelectronics supply chain attacks, insider threats, decision support, pre-attack planning, and synergistic effects between cyber and physical security systems.

Greg holds a Bachelor of Science degree with Highest Honors in Nuclear Engineering from the University of Illinois at Urbana-Champaign (1983), and Master of Science and Doctor of Philosophy degrees from the University of Illinois at Urbana-Champaign (1985, 1987).  Greg is a Fellow of the International Association for the Advancement of Space Safety.
