Dr. Casey specializes in geotechnical site investigations, geomechanics, construction induced vibrations, slope failures, and geotechnical engineering. He has performed analysis on topics including subsidence, differential settlement, characterization of soil and rock constitutive behavior, as well as drained and undrained earth responses. He has been involved in analyzing the effect of construction induced vibrations on nearby structures, such as those caused by pile driving or rock crushing. He has analyzed the stability of tailings dams and been involved in the causation analysis of tailings dam and natural slope failures. He has also evaluated the stability of retaining walls and their displacement due to nearby pile driving.

Prior to joining Exponent, Dr. Casey was a research assistant in the Department of Civil and Environmental Engineering at the Massachusetts Institute of Technology (MIT). His doctoral research focused primarily on an experimental investigation into the strength and consolidation properties of clayey soils and mudrocks up to very high effectives stresses. His research also included the development of laboratory equipment, specifically a high pressure triaxial system together with auxiliary equipment for the testing of soils and soft rocks. He has developed models to estimate the permeability of mudrocks for situations in which field testing is infeasible and to predict horizontal stresses in deep basins based on sediment composition. During his time at MIT, Dr. Casey contributed to other research projects including the laboratory testing of sand specimens to establish critical state behavior, and an experimental investigation into the effects of pore fluid composition on mechanical properties. He has assisted in teaching an undergraduate course on the mechanics of solids and soils, as well as a graduate level class on advanced laboratory testing of soil. He has also worked on a model to predict multi-phase fluid flow for conventional reservoir rocks.
