Antonios Vytiniotis

Managing Engineer, Exponent
Dr. Vytiniotis is a managing engineer in Exponent’s Civil practice, a member of the Geo-Institute’s Deep Foundation and Computation Geotechnics committees and a regional director for the Society of Construction Law – North America. He has background in structural and geotechnical engineering, geotechnical earthquake engineering, and numerical analysis. Dr. Vytiniotis has worked on numerous projects in more than 20 states and multiple countries, assisting project owners, law firms, insurance companies and developers. His analyses consist of assessing soil improvement, soil-structure interaction, dam safety, causation of MSE wall failures, effects of adjacent construction (such as vibrations or pile driving), soil heave or settlements, pipeline installation, water intrusion, and backfill quality. He is experienced in evaluating slope stability, performing mechanical and flow-through-porous media finite element analyses and soil-structure interaction using various software. Additionally, Dr. Vytiniotis has performed research on the seismic response of pile-supported wharves, seismic slope stability, the effectiveness of prefabricated vertical drains (earthquake drains) and soil densification in reducing liquefaction risk, the effect of gravel drains in amplifying seismic accelerations, and numerical simulations of centrifuge experiments. In the past, Dr. Vytiniotis gained international experience in Greece and Switzerland, and was appointed lecturer at MIT.
