Prof. Constantinos V. Chrysikopoulos received his B.S. in Chemical Engineering, University of California, San Diego (1982), M.S. in Chemical Engineering, Stanford University (1984), Engineer Degree (1986) and Ph.D (1991) both in Civil and Environmental Engineering, Stanford University. He worked: (1991-2004) in the Department of Civil and Environmental Engineering, University of California, Irvine; (2004-2013) in the Department of Civil Engineering, University of Patras, Greece, (2013-present) in the School of Environmental Engineering, Technical University of Crete, Greece. He is the author of 114 peer-reviewed articles in professional journals, 4 chapters in refereed professional books, and 225 other publications. His research has focused on various experimental as well as theoretical aspects of contaminant transport in porous media and environmental systems. Current research areas include the fate and transport of biocolloids (viruses, bacteria) and nanomaterials in subsurface formations, transport of polydisperse colloids in natural fractures, and dissolution of multi-component nonaqueous phase liquids in porous media.
