Nestor Cardozo is an associate professor at the University of Stavanger, Norway, where he teaches undergraduate and graduate courses on structural geology and its application to petroleum geosciences. He has been involved in several multidisciplinary research projects to realistically include faults and their associated deformation in reservoir models. He is the author of several widely used structural geology and basin analysis programs for Macs.

Donald M. Fisher is a structural geologist and professor at Pennsylvania State University, where he leads a Structural Geology and Tectonics research group. His research on active structures, strain histories and deformation along convergent plate boundaries has taken him to field areas in Central America, Kodiak Alaska, northern Japan, Taiwan and offshore Sumatra. He has been teaching structural geology to undergraduate and graduate students for more than 20 years.
