Dr. Coccia specializes in geotechnical engineering, unsaturated soil mechanics, geotechnical site investigations, experimental soil testing, field instrumentation, and the constitutive modeling of soil properties and behavior. He has experience examining the performance of foundations on expansive and collapsible soils, grading and drainage issues, hydro-mechanical response of mechanically stabilized earth (MSE) embankments, MSE walls, has performed investigations into slope stability failures, has evaluated the performance of landfill sites developed using deep dynamic compaction (DDC), and is proficient in the development of advanced geotechnical testing equipment. He has also evaluated the thermo-mechanical response of municipal solid waste (MSW) landfills, investigated the face stability of underground tunnels with a deformable lining, and been involved in the installation, instrumentation, and evaluation of drilled shaft geothermal foundations.

Prior to joining Exponent, Dr. Coccia was a graduate research assistant at the University of Colorado - Boulder (CU Boulder), where he earned a Ph.D. in civil engineering. His dissertation work primarily focused on the influence of temperature on the secondary deformation behavior of saturated and unsaturated soils. As part of this research, Dr. Coccia developed a new high pressure, thermal isotropic cell for soil testing. The results of the study led to the development and validation of a new constitutive model capable of predicting the thermal deformation response of saturated and unsaturated soils using the concept of thermally-accelerated secondary consolidation. In addition to his research work at CU Boulder, Dr. Coccia participated in the Discovery Learning Apprenticeship Program, providing mentorship to an undergraduate student interested in pursuing graduate work in geotechnical engineering, and has served as an instructor for undergraduate soil mechanics laboratory courses. Following his graduate research work at CU Boulder, Dr. Coccia also participated as a visiting graduate student at the University of California - San Diego (UCSD).
