Biographical Info

Dr. Georgopoulos is Professor of Environmental and Occupational Medicine at Rutgers University – 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 Rutgers Environmental and Occupational Health Sciences Institute (EOHSI). Dr. 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 Rutgers University, Princeton University, and USFDA’s Center for Toxicoinformatics (funded by USEPA 2005-2010). He is also Director of the Informatics 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). [read more…]
