Attained a Ph.D., P.E. and a geotechnical engineering expert with more than 40 years of professional experience in foundation engineering, construction materials, and geoengineering, including over 30 years providing expert witness services through consultations, depositions, and trial testimony in civil and construction-related matters. His forensic investigation experience includes construction defect and failure investigations; asphalt pavement material investigations; evaluation of Portland cement concrete material problems; low strength gain of concrete associated with casino construction; gunite deterioration in pools; foundation failures; expansive and collapsible soils; concrete coating investigations; and slip, trip, and fall investigations.

His technical work encompasses foundation engineering and soil mechanics, including hydrocollapsible and expansive soils, sulfate-related soil conditions, collapse prediction, and characterization of soluble salt content in soils from arid and semi-arid regions. His research and applied investigations address foundation performance, soil behavior, and subsurface conditions affecting residential and commercial structures.

He also has extensive experience in construction materials and pavement engineering, including asphalt binders, hot mix asphalt performance, pavement rutting resistance, fracture mechanics of paving materials, and nondestructive evaluation methods such as ultrasonic characterization. His work in these areas supports evaluation of roadway performance, material properties, and the durability of concrete and asphalt systems.

In addition, his background includes rock mechanics and drilled shaft foundations, as well as geotechnical site characterization and laboratory and field investigations related to rock behavior and deep foundation systems. His work has included research and technical evaluation associated with subsurface conditions and foundation design considerations.

He currently serves as Professor of Civil Engineering at a public research university, where he has held faculty appointments and has served as a full professor for over 30 years, with responsibilities including research and graduate-level instruction in soil mechanics, foundation engineering, rock mechanics, and highway and construction materials. Earlier in his career, he served as Project Manager and Senior Geotechnical Engineer with Battelle Project Management Division and as Principal Research Scientist with Battelle Columbus Laboratories, directing and managing multidisciplinary geoengineering and materials research programs.

He is a Registered Professional Engineer in Ohio and Nevada and earned a Ph.D. and M.S. in Civil Engineering and an M.B.A., along with a Bachelor of Civil Engineering degree. His professional involvement includes membership on the Forensic Practice Committee of the Technical Council on Forensic Engineering of the American Society of Civil Engineers, contributing to preparation of the Manual of Forensic Engineering Practice, and membership in ASTM Committee D-18 on Soil and Rock, including multiple related subcommittees; across years of academic, research, and forensic practice, his work has addressed foundation performance, pavement and concrete materials behavior, soil-induced structural movement, and construction-related failures.
