Advancing the State of the Practice

Our geotechnical / geoenvironmental group is led by Neven Matasovic, PhD, PE, GE. He has advanced the state of the practice through collaboration in applied research and development with leading universities. Recent topics include development of models for evaluation of stresses and strains in composite liner systems during seismic events, development of nonlinear effective-stress site response analysis models, and contribution to seismic design of municipal solid waste and hazardous waste landfills through back-analysis of case histories and advanced testing of difficult to sample and test geomaterials. Dr. Matasovic is an active contributor to Federal Highway Administration (FHWA) sponsored projects and has co-authored technical guidance documents for FHWA and Transportation Research Board of the National Academies.

Dr. Matasovic leads a team of focused geo-professionals which includes eight California-Registered Geotechnical Engineers (GEs) and nine Certified Engineering Geologists (CEGs).
