Walter Illman, PhD

Professor Illman has over 20 years of academic and consulting experience in a wide range of hydrogeological problems worldwide, particularly in developing high-resolution site characterization techniques, applying advanced groundwater flow and transport models, and developing innovative laboratory and field methods to solve complex environmental problems. His current research interests include field investigations of subsurface heterogeneity in both porous and fractured geologic media, in particular the innovative interpretation of single- and cross-hole hydraulic tests. He is considered one of the pioneers in developing hydraulic tomography, a new subsurface characterization method to image heterogeneities of hydraulic conductivity and specific storage. He has applied hydraulic tomography and related techniques in a variety of geological environments including highly heterogeneous porous and fractured media. Professor Illman is the author of over 60 publications in peer-reviewed journals and has served as an Associate Editor for Water Resources Research and Groundwater. Other notable published work includes a book on Bioremediation and Natural Attenuation: Process Fundamentals and Mathematical Models, published by John Wiley & Sons, Inc. of which he is a coauthor.
