Dr. Richard W. Stephenson, P.E.
Missouri University of Science and Technology
Chancellor's Professor in Civil Architecture and Environmental Engineering (Emeritus)

Dr. Richard W. Stephenson, received his Ph.D. in civil engineering from Oklahoma State University in 1971.  Since then he has been at the Missouri University of Science and Technology in various capacities.  He has served as geotechnical engineering area head and interim department chairman.  Dr. Stephenson has conducted numerous dam safety investigations for the U.S. Army Corps of Engineers as well as for various public and private consulting clients.  His research interests include deep foundations, geotechnical earthquake engineering, helical anchors, and laboratory characterization of soil behavior including hydraulic conductivity, behavior of silt soils, and deterioration of foundations of Egyptian antiquities.  Dr. Stephenson is a Fellow of ASCE, a member of the Academy of Civil Engineers at the Missouri University of Science and Technology, and a registered professional engineer. He currently holds the title of Chancellor’s Professor and Professor Emeritus. 

Dr. Ronaldo Luna, P.E.
Saint Louis University
Professor of Civil Engineering

Dr. Ronaldo Luna has been a Professor of Civil Engineering at Saint Louis University since 2014.  He teaches courses at the graduate and undergraduate level in the field of geotechnical and civil engineering. His research interests lie in the dynamic response of soils and liquefaction, geographic information systems in civil engineering, and advances in soil mechanics/foundations, and earthquake engineering. He was a professor at the Missouri University of Science and Technology in Rolla, MO, for fifteen years. Previously he was an assistant professor at Tulane University, New Orleans, LA.  He obtained his bachelor of science in civil engineering in 1983, from the University of Maryland, College Park, MD, and master of science in geotechnical engineering in 1985 from Purdue University, West Lafayette, IN. He earned his Ph.D. in 1995 from the Georgia Institute of Technology, Atlanta, GA. Dr. Luna has practiced as a geotechnical engineer in the west coast and the central US and currently in the region and internationally.  He is a registered professional engineer in the states of Missouri, California, and Washington and holds his consulting practice as Luna Consulting, LLC. He has published over 120 technical papers. Dr. Luna is a Fellow with the American Society of Civil Engineers since 2007 and was recently inducted as a Diplomate, Geotechnical Engineering, with the Academy of Geo-Professionals.
