Professional Interests

Dr. Lewis specializes in the areas of soil mechanics, seepage and groundwater, foundation engineering, design and construction of earth dams, and pavement analysis and design. His current research interests include seepage into excavations, seepage characteristics of impoundments, dynamic properties of copper tailings, behavior of laterally loaded piers, geotechnical properties and consolidation behavior of industrial sludge, and analysis/design of culverts/tunnels built by the inflatable form process.

Dr. Lewis is also the Founder and past Director of the Pitt Engineering Impact Program (1969-1999). He has been a member of the Maritime Transportation Research Board of Directors (National Research Council), and has served the Pittsburgh Section (ASCE) as a Director and President of the Associate Member Forum. Dr. Lewis is a member of ASCE, the International Society of Soil Mechanics and Foundation Engineering , and the following national honor societies: Sigma Xi, Tau Beta Pi, Pi Mu Epsilon, and Chi Epsilon.
