Ph.D., P.E., is the co-founder and principal engineer at Advanced Geo-Design Inc.

John (Yan) Zhang

Before starting the business of Advanced Geo-Design Inc., he was a Project Engineer with Geosyntec’s Geostructural and Construction Engineering practice group. He worked with multi-disciplinary engineering groups within Geosyntec to provide various geo-structural designs for clients across the US.

Before joining Geosyntec, he had seven years of geotechnical design-build experience with Keller North America, the largest geotechnical specialty contractor in North America. During his time there, he worked in both the Chicago-area and Irvine-area offices, focusing on developing innovative, cost-effective, and constructible designs, as well as quality control/quality assurance measures for a variety of specialty ground improvement methods. These included seismic and static solutions such as aggregate piers/stone columns, soil densification and soil mixing, rigid inclusions, and support of excavation systems involving cantilever, tieback, and internal bracing. He has geotechnical engineering experience in soil-structure interaction problems, numerical analysis using Plaxis 2D/3D and FLAC, foundation design, liquefaction analysis and mitigation design, load testing, and development of plans and performance specifications.  

As a specialty contractor and geo-structural designer in the Midwest, SoCal, and Bay Area, he worked extensively with cross-functional teams (engineers, estimators, construction project managers, safety managers, and specialty equipment operators). John’s project portfolio covered both the private and public sectors, with values of up to $26MM. He worked on numerous industrial, commercial, and residential projects, as well as schools, hospitals, and transportation infrastructure.
