John F. Shortle

John F. Shortle is a Professor and Chair of the Systems Engineering and Operations Research Department at George Mason University's Volgenau School of Engineering. He has been an active member of the Center for Air Transportation Systems Research (CATSR) since its inception in 2003 and has held numerous leadership roles including President of the INFORMS Simulation Society (2016-2018), President of the Association of Chairs of Operations Research Departments (2022-2023), and Program Chair of the Winter Simulation Conference (2023).

Dr. Shortle's research focuses on applying deep mathematical creativity to solve applied problems of societal significance, particularly in understanding how randomness and uncertainty impact system behavior and design. His specific research interests include simulation, queueing theory, air transportation, aviation safety, power systems, and telecommunications. Many of his current projects are funded by the FAA and NASA to enhance the safety of future air transportation systems.

His publication record demonstrates a strong trajectory toward increasingly sophisticated applications of queueing theory and simulation to aviation safety challenges. Recent work has incorporated machine learning techniques like variational autoencoders for synthetic flight track generation, dynamic event trees for collision risk assessment, and frameworks for uncertainty analysis in safety models. His research bridges theoretical mathematics with practical applications in critical infrastructure systems.

Dr. Shortle has secured significant research funding from federal agencies including the Federal Aviation Administration (FAA), NASA, and the US Department of Energy. His editorial service includes associate editor roles for Aerospace (2022-present), IEEE Transactions on Reliability (2010-2016), and Journal of Probability and Statistical Science (2003-2011). As co-author of the widely used textbook 'Fundamentals of Queueing Theory' (5th edition, 2018), he has made substantial contributions to the education of operations research professionals worldwide.

He leads research activities through the Center for Air Transportation Systems Research, where his team develops advanced simulation frameworks for aviation safety analysis, including collision risk models, event tree analysis, and wake vortex safety assessment. His work on the Integrated Safety Assessment Model has been particularly influential in advancing aviation safety practices.
