Meet Our Faculty

  • Associate Professor, Sid and Reva Dewberry Dept of Civil, Environmental, and Infrastructure Engineering, Volgenau

    Flood hazards engineering and resilience
  • Professor Emeritus, Systems Engineering Operations Research, Volgenau

    Stephen Nash is professor emeritus in the Department of Systems Engineering and Operations Research. From 1998-2005, he served as associate dean for graduate studies and research and from 2012-2018 as senior associate dean of the Volgenau School of Engineering. From 2005-2008, he was the Program Director for the Operations Research program at the National Science Foundation, on leave from George Mason University. Prior to coming to George Mason University, he taught at The Johns Hopkins University.
  • Associate Dean for Research, Volgenau
    Professor, Systems Engineering Operations Research, Volgenau

    Throughout his career, Art Pyster has played a leading role with systems and technologies in telecommunications, aerospace, defense, air traffic control, and computing.  
  • Assistant Professor, Systems Engineering and Operations Research, Systems Engineering and Operations Research

    The world around us is continually being shaped by intelligent and autonomous systems that are typically developed as independent systems but operate in a system of systems environment. Ali K. Raz research focus is on understanding the collaborative nature of autonomy and developing systems engineering methodologies for integrating autonomous systems.
  • Director, Center for Air Transportation Systems research, Volgenau
    Associate Professor, Systems Engineering and Operations Research, Systems Engineering and Operations Research

    Lance Sherry is an Associate Professor in the Systems Engineering and Operations Research department and serves as Director of the Center for Air Transportation Systems Research at the Volgenau School of Engineering at George Mason University.
  • Professor and Chair Systems Engineering and Operations Research, Systems Engineering and Operations Research

    John Shortle applies deep mathematical creativity to applied problems of societal significance. He is motivated to understand how randomness and uncertainty impact the behavior and design of a system. His specific interests include simulation, queueing, and analysis of rare events with applications in air transportation, aviation safety, power systems, and telecommunications. Many of his current research projects are funded by the FAA and NASA supporting the goal of making the future air transportation system safer than it is today.
  • Ariela Sofer

    Associate Dean, Administration and Faculty Affairs, Volgenau Professor, Systems Engineering and Operations Research, Volgenau

    Ariela Sofer is interested in nonlinear programming, optimization in medical applications, and systems thinking.  Sofer is currently Academic Director of The International Council on Systems Engineering (INCOSE).  She has served as Secretary of the Board of Trustees of the Institute of Industrial and Systems Engineers (IISE), as Vice President for Sections and Societies of The Institute for Operations Research and Management Science (INFORMS) and as President of the Association of Chairs of Operations Research Departments (ACORD).
  • Assistant Professor, Systems Engineering and Operations Research, Volgenau

    Vadim Sokolov works on building robust solutions for large scale complex systems analysis, at the interface of simulation-based modeling and statistics. This involves developing new methodologies that rely on agent-based modeling, Bayesian analysis of time series data, design of computational experiments and development of open-source software that implements those methodologies. Inspired by an interest in urban systems, he co-developed mobility simulator called "Polaris" which is currently used for large scale transportation networks analysis by both local and federal governments.
  • Associate Professor, Systems Engineering and Operations Research, Volgenau

    Jie Xu’s research focuses on stochastic optimization using simulation and its implementation in high-performance and cloud computing environment, robust data-driven decision-making and uncertainty quantification, rare event simulation, and computational intelligence. Xu’s application areas of interest include revenue management, risk management, power networks, data centers, cloud, health care, and production planning.
  • Professor, Systems Engineering and Operations Research, Volgenau

    As an instructor, Abbas Zaidi’s pedagogical approach has been to challenge his students to solve real world problems as independent thinkers, utilizing their learned techniques and not relying solely on solution recipes provided in textbooks or lectures. He thinks his job as a teacher ends the moment a student becomes an independent learner. As a teacher, he finds this journey rewarding in many ways for both himself and for his students: he thinks the students have taught him more in this process. He firmly believes that learning should be a fulfilling and, therefore, a joyful experience.
