Smith, Clayton


Dr. Smith is a member of the Principle Professional Staff at JHU/APL with over 30 years of experience analyzing systems from risk, reliability, and safety perspectives. These systems included: NASA and DoD missions, payloads, ground communication systems, air traffic control systems, and missile systems. He is developing approaches to assess intentional threats against space assets using PRA and Game Theory techniques. He created and managed NASA’s International Space Station Program Probabilistic Risk Assessment specifically geared toward quantifying the safety risk during operations. Dr. Smith is currently the reliability engineering lead for APL’s Solar Probe Plus mission. He received his B.S. in Aerospace Engineering, M.S. in Engineering Management, and Ph.D. in Reliability Engineering all from the University of Maryland.

Pourali, Masoud

Dr. Masoud Pourali received his Ph.D. from University of Maryland in Reliability Engineering. His research interestes are: System Health Monitoring, Prognostics and Health Management (PHM), Bayesian Sensor Placement Optimization, Common Cause Failure (CCF) Analysis, and Application of Bayesian Techniques such as Bayesian Belief Networks in Risk and Reliability Analysis.

Metlay, Daniel

Dr. Metlay received his Bachelor of Science degrees from Caltech in molecular biology and medieval history and his Masters and Doctoral degrees in public policy from the University of California, Berkeley. He taught political science at Indiana University and MIT. He has worked in the Carter White House and with the Secretary of Energy on radioactive waste issues. Until recently he was a member of the Senior Professional Staff of the U.S. Nuclear Waste Technical Review Board, an independent federal agency charged with evaluating the technical and scientific validity of the Department of Energy’s high-level radioactive waste management program. In addition to his work in this area, Dr. Metlay has authored numerous publications dealing with technology policy, regulation, and organization behavior. Dr. Metlay has testified before Congress and several state legislative committees. His immediate research agenda is the preparation of a monograph examining the technical and institutional challenges of developing a deep-mined, geologic repository for high-level radioactive waste in the United and abroad.

López Droguett, Enrique

Enrique López Droguett is Associate Professor in the Mechanical Engineering Department at the University of Chile, and Adjunct Associate Professor at the University of Maryland, USA, and is Associate Editor for the Journal of Risk and Reliability. Dr. López Droguett conducts research on computational methods for risk, reliability, and prognostics and system health management based on deep learning for big machinery data. He has led many major studies on these topics in the oil & gas sector, nuclear energy, defense, and energy distribution networks. Dr. López Droguett has over 170 papers in archival journals and proceedings of conferences and 2 books in various areas of reliability, maintenance, and physical asset management.

Kazarians, Mardy

Mardy Kazarians is an independent consultant and owner of Kazarians & Associates, Inc. specializing in risk assessment and risk management program development and implementation of highly hazardous operations. As part of his Ph.D. dissertation at UCLA, he developed a methodology for the fire risk in nuclear power plants. He has since worked on a large number of risk assessment projects for nuclear plants in the U.S. and abroad. He has extended his knowledge of risk assessment to other industries such as petroleum refining, chemicals manufacturing as well as systems and operations handling highly hazardous materials.

Johnson, David


Dr. Johnson has more than 35 years of experience in risk-based analysis for industry and government applications. His extensive experience and knowledge in all facets of nuclear reactor probabilistic risk assessments (PRA) and expertise include probabilistic modeling and investigation of impacts of industrial endeavors, the development of quantitative risk assessment methods and the practical application of these methods to support risk management.

Fleming, Karl

Karl Fleming received his B.S. in Physics from Penn State University, Cum Laude in 1969 and his M.S. in Nuclear Science and Engineering at Carnegie-Mellon University in 1974. He has devoted his entire professional career of 45 years to the advancement and application of PRA technology in the nuclear, chemical, process, and aerospace industries. Following professional and executive level assignments at General Atomics, and Pickard Lowe and Garrick, and ERIN Engineering and Research he established an independent consulting firm in 2001 and continues to be active as an independent consultant.

Epstein, Woody

Since 1983, Dr. Epstein has worked as a mathematician and probabilistic risk assessment (PRA) professional, living in Japan since 2003. Following the Fukushima Daiichi accident, he has concentrated on the mathematical and computer modeling of extreme external events such as earthquakes, tsunami and their integration into Level 1 External Events PRA. His expertise includes risk assessment software development, project management, modeling and simulations, mathematical techniques for risk assessment, software risk assessment, and advanced research in risk assessment technology.
