Dr. Vytiniotis is a seasoned engineering sciences testifying expert who provides high-level geotechnical support and advanced studies for complex infrastructure and high-stakes disputes. His work focuses on strategic advisory services and root cause analysis, helping global clients navigate their most daunting engineering challenges across a wide range of sectors, including commercial, transportation, energy, rail, and mining.
Dr. Vytiniotis has a background in structural and geotechnical engineering, geotechnical earthquake engineering, and numerical analysis. He has testified and participated in multiple proceedings, including mediations and arbitrations. He has worked on numerous projects in more than 20 states and multiple countries, assisting project owners, law firms, utility companies, insurance companies, and developers.
His analyses consist of assessing soil improvement, soil-structure interaction, effects of vibrations and vibration isolation, construction defects, premises code compliance, dam safety, landslides, LNG and diesel tank condition assessments, API tank inspections, assessing wind turbine failures, causation of MSE wall failures, effects of adjacent construction, soil heave or settlements, frost-induced effects on soils, pipeline installation, effects of soil movements on pipelines, water intrusion, flooding, scour, 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 such as Plaxis, Flac, Geostudio, ABAQUS, LPILE, FEFLOW, HydroCAD, and GROUP. Additionally, Dr. Vytiniotis has experience in data analysis, signal processing and GIS with software such as QGIS and R.
Dr. Vytiniotis has taught classes on geotechnical engineering, liquefaction mitigation, and construction vibrations. Dr. Vytiniotis has performed research on the effects of corrosion on MSE walls and assessing state of practice codes for MSE walls. He 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. He also has research experience in constitutive soil modeling and evaluating settlements in soft soils associated with staged levee construction. He has experience in using probabilities to understand seismic risk of geotechnical components.
Dr. Vytiniotis is the Senior Vice President of Boston Society of Civil Engineers, a regional director of the Society of Construction Law North America and the Vice Chair of Geo-Institute’s Computational Geotechnics committee. He is also a member of the American Wind Energy Association (AWEA) committees, responsible for developing the structural and geotechnical standards for the soil-structure interaction of wind turbine foundations. In the past, Dr. Vytiniotis gained international experience in Greece and Switzerland and was appointed lecturer at MIT.
Dr. Vytiniotis’ doctoral research, part of a multi-university and multi-disciplinary research project, focused on performing site response analyses to help port authorities manage their seismic risk. He collaborated with other research groups specializing in soil-structure interaction and port operations in order to evaluate the effect of earthquake-induced soil deformations on failure of individual structural components by means of fragility curves and disruption of port operations.
During his doctoral studies at MIT, Dr. Vytiniotis was a teaching assistant for a graduate-level course in advanced soil mechanics as well as a guest lecturer for a graduate-level course in soil dynamics.
Expanding Opportunities for Overseas Enforcement of PRC Judgments and Awards
Amanda Rasmussen and Kristine Kwok examine the gradual expansion of reciprocal enforcement regimes and the growing recognition of PRC judgments and arbitral awards in major jurisdictions, highlighting increasingly favorable conditions for cross-border recovery.
12 Secretariat Experts Recognized in Lexology’s 2025 Commercial Litigation Report
12 Secretariat experts have been recognized in the Lexology Index 2025 Commercial Litigation report for their exceptional work supporting clients in some of the world’s most complex and high-stakes disputes.
Managing Director Bob Broxson provided expert reports, deposition, and trial testimony on behalf of Marathon Oil Company in a historic trial – the first held by the Texas Business Courts since their opening in September 2024. The landmark case stemmed from natural gas delivery interruptions during the 2021 Winter Storm Uri.
