Biography

Panos G. Georgopoulos is Professor of Environmental and Occupational Medicine at the University of Medicine and Dentistry of New Jersey - Robert Wood Johnson Medical School. He is also a member of the Graduate Faculties of Chemical and Biochemical Engineering, Biomedical Engineering, and of Environmental Sciences at Rutgers University, and a member of the Environmental and Occupational Health Sciences Institute (EOHSI), which is a joint institute of UMDNJ-RWJMS and Rutgers. Georgopoulos received his M.S. and Ph.D. Degrees in Chemical Engineering from the California Institute of Technology (Caltech) and his Dipl. Ing. Degree from the National Technical University of Athens. At EOHSI he established and directs the Computational Chemodynamics Laboratory (CCL), a state-of-the-art facility for informatics and modeling of complex environmental and biological systems. Furthermore, he directs the State-funded Ozone Research Center and co-directs the Center for Exposure and Risk Modeling (CERM) at EOHSI. He is Co-Director of the Environmental Bioinformatics and Computational Toxicology Center (ebCTC), a research consortium of UMDNJ-RWJMS, Princeton University, Rutgers University and USFDA's Center for Toxicoinformatics. He is also Co-Director of the Bioinformatics, Biostatistics and Computational Toxicology Core for the NIEHS Center for Environmental Exposures and Disease (CEED) at EOHSI. He served as Director of the USDOE-funded Center of Expertise in Exposure Assessment of the Consortium for Risk Evaluation with Stakeholder Participation (CRESP).

Georgopoulos has participated in both research and teaching in the graduate programs of Rutgers and UMDNJ-RWJMS and has developed innovative course materials in modeling and informatics related to environmental health applications. He has been the primary doctoral thesis advisor to 18 students, with 11 Ph.D. degrees awarded since 1997, and has been mentor to 24 post-doctoral fellows. His research interests involve the development and application of novel mathematical and computational methods for diagnostic and mechanistic studies of multipathway physicochemical processes taking place in interacting environmental and biological systems. The aim of this research is to improve the understanding and quantification of human exposure and biological mechanism-based dosimetry and risk for environmental toxics; this is being accomplished through the ongoing development of a consistent mechanistic multiscale modular computational framework for source-to-dose-to-effect modeling of toxicant dynamics. Outcomes of this research include integrative computational models of toxicokinetic and toxicodynamic processes at the cellular, tissue and whole body levels.

Georgopoulos has lectured as an invited speaker at universities, including the Harvard School of Public Health, Johns Hopkins University, Stanford University, Illinois Institute of Technology, University of Minnesota, and others. He has published more than 125 peer-reviewed articles and chapters in scientific journals, books and proceedings, and has authored or co-authored several State and Federal Government Documents and numerous technical reports. He has received awards and honors, including the DuPont Education and Research Award, for his work on environmental pollution and health. He served on editorial boards of scientific journals and currently serves as member of various national and international scientific and technical committees on environmental issues.

Georgopoulos works in close association with Paul J. Lioy, Director of the Exposure Science Division of EOHSI.
