Christopher, Barry, Ph.D., P.E.
Barry Christopher, Ph.D., P.E., is an independent geotechnical engineering consultant specializing in: reinforced soil and other ground improvement technologies; geosynthetics application and design; and, geotechnical/geosynthetics testing and instrumentation. He has a BSCE from U.N.C., Charlotte, a MSCE from Northwestern University, and a Ph.D. from Purdue University. He is a registered Professional Engineer in seven states and has over 30 years of experience in geotechnical engineering. Dr. Christopher was formerly Vice President, Technical Services for Polyfelt Americas,
in Atlanta, Georgia, where he was responsible for geosynthetic application engineering, research and development and quality assurance programs. Before joining Polyfelt, he was Principal Engineer and Laboratory Director with STS Consultants, Ltd., Northbrook, Illinois. He has authored over 100 Technical papers including: eight design manuals – FHWA-NHI Mechanically Stabilized Earth Walls and Reinforced Soil Slopes, 2001 and 2009 LRFD revisions; FHWA Reinforced Soil Structures, 1990, FHWA Geotextile Engineering Manual, 1985; FHWA Geosynthetics Design and Construction Guidelines, 1989 and 1995, 2001 and 2008 revisions; FHWA-NHI Manual on Subsurface Investigations, 2002; and ASDSO Use of Geosynthetics in Dams, 1989; a textbook, Geosynthetics Engineering, 1997; two book chapters; and, three National Cooperative Highway Research Program Syntheses on Pavement Subsurface Drainage Systems, Maintenance of Highway Edgedrains, and Geosynthetic Reinforcements in Roadway Sections. He has given many presentations and short courses on various aspects of geotechnical engineering and is currently a principal lecturer for the FHWA in workshops on geosynthetics, mechanically stabilized earth walls and slopes, geotechnical instrumentation, and subsurface investigation as well as an alternate instructor for courses in soils and foundations and in pavement subsurface drainage design. He was also a co-lecturer in a series of NICET training seminars on geosynthetics in waste containment for CQC and CQA personnel. He was the principal investigator for the FHWA study on “Behavior of Reinforced Soil” and is currently a consultant to HITEC on evaluation of earth retaining systems.
Other professional activities include: past president of the North American Geosynthetics Society; council member of the International Geotextile Society; fellow member and past chair of ASTM Committee D35 on Geosynthetics; technical chair for Geosynthetics ’91; chair for Geosynthetics ’93; Past technical committee chair for the Industrial Fabrics Association International; and, member ASCE, the Geo-Institute and NSPE.
