Incumbent
Assumed office 2005

Yannis C. Yortsos is the Dean of the Viterbi School of Engineering at the University of Southern California.^[1] Since June 2005, he has served as Dean of the USC Viterbi School of Engineering and has held the Zohrab A. Kaprielian Chair in Engineering. He has also held the Chester F. Dolley Chair since January 1995. He was elected to the National Academy of Engineering in February 2008.

Education

Yortsos received a B.Sc. degree from the National Technical University, Athens, Greece, in 1973, and M.Sc. and Ph.D. degrees from the California Institute of Technology, in 1974 and 1979, respectively, all in chemical engineering. He joined USC in 1979 as an assistant professor in petroleum and chemical engineering and was promoted to the ranks of associate professor and full professor in 1984 and 1990, respectively. His professional experience includes invited professor appointments at the Universite Paris, Orsay, France, in 1997, 1999 and 2001; and at the Université Pierre et Marie Curie, Paris, France, in 1990, 1997 and in 1999; associate researcher at the Centre National de la Recherche Scientifique in France; visiting professor in the departments of chemical engineering at California Institute of Technology in 2001, and at Stanford University in 1986; and visiting professor in the Department of Mathematics and Computer Science at Clarkson University in 1986. In addition, he held student summer training appointments in Serlachius Oy Paper Factory, Mantta, Finland in 1972, and in Gaz de France, Strasbourg, France in 1971. An active participant in peer review of the Yucca Mountain Project for the disposal of high-level radioactive waste, Yortsos was a member of the Peer Review Committee on Thermal Hydrology in 1995, a member of the Panel on Expert Elicitation on the Near-Field/Altered Zone Environment in 1997-1998, and an advisor to the TSPA-VA Peer Review Committee in 1998-1999.

Honors and Awards

Yortsos’ awards and honors include an honorary doctoral degree from Dubna International University (2009) and the Society of Petroleum Engineers (SPE) 2008 Western North America Reservoir Description and Dynamics Award. An elected Foreign Member of the Russian Academy of Natural Sciences (2001), Yortsos is also a recipient of the academy’s Kapitza Medal. He received a Distinguished Educator Award from the Orange County Engineering Council in 2000; the Rossiter W. Raymond Award of the AIME for Outstanding Technical Paper by an author younger than 33 years of age (1985); the Distinguished Service Award of the Pi Epsilon Tau in 1984; the ARCO Oil and Gas Outstanding Jr. Faculty Award in 1981; and a Greek Government Scholarship for his undergraduate studies from 1968- 1973. He served as the executive editor of the Society of Petroleum Engineers Journal (SPEJ) and on the editorial boards of several journals, including Transport in Porous Media, the SIAM Journal on Multiscale Modeling and Simulation, the SPEJ and the American Mathematical Society. From 2006-2010, he served as SPE editor-in-chief of all technical journals. He is a University Fellow of the USC Center on Public Diplomacy, and serves on the advisory boards of a number of institutions worldwide, including the School of Information Science and Technology of Tsinghua University, and the Academic Advisory Council of the Greek Embassy in the United States. He is the NAE Section 11 liaison to the National Research Council.

Research and Teaching

Yortsos’ research and teaching interests are in the general areas of fluid flow, transport and reaction processes in porous and fractured media. He has supervised 27 Ph.D. theses and 8 post-doctoral researchers, and was the external examiner in seven Ph.D. theses, at the University of California, Berkeley; Alberta University, Canada; University of Bergen, Norway; University of Paris VI and University of Paris XI, France; and at Delft University, the Netherlands. The author of more than 145 refereed publications, Yortsos has given more than 120 invited talks and presented more than 80 conference papers. Included in his publications are studies of steam injection, heat transfer, in-situ combustion and thermal recovery processes in porous media; the development of analytical solutions to mathematical models of transport in porous media; viscous flow instabilities in porous media and Hele-Shaw cells; viscous flows in constricted geometries; filtration and formation damage in porous media; application of percolation theory to immiscible displacement, adsorption and reaction processes in porous media; application of fractal geometry to the identification of parameters in the subsurface; the evolution of gas in phase change in porous media, as in boiling and related geothermal problems; the modeling of mass transfer in porous media with application to soil remediation; and the application of optimization methods in subsurface flows.

Administrative

Yortsos served as associate dean for academic affairs between July 1, 2001 and June 2003, and as senior associate dean for academic affairs between July 1, 2003 and May 31, 2005, also at the Viterbi School. From September 1991 to July 1997, Yortsos was chairman of the Department of Chemical Engineering.
