Dr. Perri specializes in soil mechanics, geotechnical engineering, foundation engineering, and earthquake engineering. He has over 20 years of experience conducting civil engineering studies in multiple states, Europe, and several countries in North, Central, and South America.

Dr. Perri has extensive experience in the evaluation of flood control systems, including canals, dams, and levees, as well as in the study and evaluation of underground pipelines and buried structures, foundations, retaining structures, mass grading, and landslides. He provides engineering consultation to clients looking for evaluation of cause and origin of failures, risk assessment, mitigation alternatives, and proactive technical reviews of design and construction documents.

Dr. Perri has completed a full range of geotechnical studies for levee systems, reservoir dams and mine tailings dams, involving the development of exploration plans, site characterization, seepage evaluation, strength characterization, static slope stability analyses, erosion potential evaluation, probabilistic risk assessment, liquefaction analyses, and seismic vulnerability assessments. In addition, he has worked on the development and evaluation of preliminary alternative designs for remediation of levee deficiencies and liquefaction mitigation through ground improvement. He has performed canal inspections and worked on the expansion of the Panama Canal. Dr. Perri has a background in arctic engineering, including evaluation of depth of freeze and thaw in soils, the physical and thermal properties of frozen ground, pile capacity in permafrost and thawing ground, and has experience with projects in Siberia and in the State of Alaska. Dr. Perri has strong expertise in mass grading, slope creep, slope stability and landslides, slope stabilization measures, design and testing of ground anchors and soil nails, evaluation of fly-ash embankments, structural and geotechnical instrumentation and monitoring, rigid and flexible retaining walls, including Mechanically Stabilized Earth (MSE) walls, foundation design, soil interaction with pressurized and gravity pipelines, commercial buildings, design and analyses of tunnels, earth pressures, moisture intrusion, expansive soil, stiff fissured clays, peat, ground subsidence, soil settlement, collapsible soils, sensitive soils and design of pile foundations for offshore structures. He has also completed evaluations of soil improvement systems such as wick drains, stone columns, deep soil mixing (DSM), rigid inclusions, piled embankments, and compaction grouting. Dr. Perri has also experience in conducting studies on ground vibrations, site amplification, wave propagation, liquefaction, and lateral spreading. He has worked on the design of static and seismic ground improvement systems, deep excavations, embankments, and deep and shallow foundations for hospital buildings. Dr. Perri has international experience in the countries of Venezuela, Mexico, Peru, Ecuador, Colombia, Brazil, Panama, Nicaragua, Costa Rica, Italy, Poland, Vietnam, and Canada.

Dr. Perri's doctoral research focused on geotechnical earthquake engineering, deep foundations for offshore structures, geotechnical constitutive modeling, and human factors in geotechnical engineering failures. At the University of California, Berkeley, he served as a graduate student researcher and was the teaching assistant for six graduate and undergraduate courses in soil mechanics, waste containment systems, risk assessment, and strong motion seismology.
