John A. Miller is a Professor of Computer Science at the University of Georgia. He has been the Associate Head for 6 years and has been the Graduate Coordinator for 13 years. His research interests include (i) Modeling & Simulation, (ii) Web Services/Workflow, (iii) Database Systems, (iv) Data Science/Big Data, and (v) Bioinformatics. Dr. Miller received the B.S. degree in Applied Mathematics (AM) from Northwestern University in 1980 and the M.S. and Ph.D. in Information and Computer Science (ICS became CoC) from the Georgia Institute of Technology in 1982 and 1986, respectively. His doctoral minor was in Industrial and Systems Engineering (ISyE). As part of his undergraduate co-operative education program, he worked as a Software Developer at the Princeton Plasma Physics Laboratory, assisting physicists conducting experiments on two advanced fusion reactors, the Princeton Large Torus (PLT) and the Poloidal Divertor Experiment (PDX).

Dr. Miller is the author of over 200 publications (h-index = 51) in the areas of (i) Modeling & Simulation (modeling methodology, simulation environments, Web-based simulation and ontology driven simulation), (ii) Web Services/Workflow (discovery, composition, semantics and quality of service), (iii) Database Systems (transactions, object-oriented databases and XML databases), (iv) Data Science/Big Data (predictive analytics, forecasting, graph analytics and use of semantics), and (v) Bioinformatics (workflows, databases, ontologies and simulation). Notable projects include the SIMODULA Query Driven Simulation Environment, the Active KDL Functional, Object-Oriented Database System, the METEOR2 Workflow Management System, the JSIM Web-Based Simulation System, the Db4XML XML Database System, the METEOR-S Semantic Web Services Suite based on WSDL-S/SAWSDL, the EuPathDB Integrated Database Portal, the Discrete-Event Modeling Ontology (DeMO), and the SCALAble simulaTION system (ScalaTion).

Dr. Miller has been active in the organizational structures of research conferences in all these areas. He has served as General/Program Chair for the 1993 Annual Simulation Symposium (ANSS), the 2001 Association for Computing Machinery - Southeast Conference (ACM-SE), the 2014 Winter Simulation Conference (WSC), the 2015 International Conference on Web Services (ICWS), the 2016 Service Computing Conference (SCC), the 2017 Service Computing Conference (SCC), and the 2019 International Conference on Web Services (ICWS). He has also served on the Organizational Committees of the Workshop on Research Issues in Data Engineering (RIDE), the 1st International Workshop on Semantic Web Services and Web Process Composition (SWPC) the NSF Workshop on Workflow and Process Automation in Information Systems (NSF-WF), and the Conference on Industrial & Engineering Applications of Artificial Intelligence and Expert Systems (IEA/AIE). Dr. Miller has also been active in the editing of journals. He is an Associate Editor for the ACM Transactions on Modeling and Computer Simulation (TOMACS), SIMULATION: Transactions of the Society for Modeling and Simulation International, (SIM), and previously IEEE Transactions on Systems, Man and Cybernetics (TSMC), as well as an Editorial Board Member for the Journal of Simulation (JOS) and International Journal of Simulation and Process Modelling (IJSPM). In addition, he has been a Guest Editor for the IEEE Transcations on Services Computing, (TSC), Journal of Simulation (JOS), IEEE Potentials (IEEE-PT), and International Journal in Computer Simulation (IJCS).
