Philip J. Shaller, Ph.D., P.G., C.E.G.

Senior Managing Consultant

Dr. Philip Shaller brings over 25 years of experience in the field of engineering geology, with significant expertise in the assessment and mitigation of geologic hazards, including landslides, debris flows, alluvial fan flooding, post-wildfire flooding hazards, expansive and collapsible soils, and coastal hazards. He also has considerable experience in geologic and geomorphic site characterization, aerial photo analysis, and the logging of subsurface borings including mapping, subsurface characterization and construction observation during construction of the Getty Center museum complex in Los Angeles, CA; investigation of a proposed railroad alignment between Sheridan, WY and Miles City, MT, geological and geochemical investigation of the Ka Loko Dam failure in Hawaii, numerical modeling of the La Conchita landslide in California, investigation of damaged infrastructure and ground deformation following the Northridge Mexicali, and Bhuj (India) earthquakes, investigation of a potentially life-threatening landslide at the Matahina Reservoir complex in New Zealand, and a geologic feasibility and risk assessment of a pipeline installation through the Niger Delta. He has consulted extensively on high profile projects across the globe, and has defended his opinions in depositions, mediation and trial.
