REPRESENTATIVE CONSULTING EXPERIENCE
Dr. Edmund Medley, Ph.D., PE, CEG, F.ASCE has over 30 years of unusually varied international experience in geotechnical and geological engineering consulting, mineral exploration prospecting, failure investigation, project management, litigation testifying, academic research, teaching, and lecturing. Dr. Medley specializes in the engineering and geological characterization of bimrocks (block-in-matrix rocks), complex geological mixtures of rock and soil such as melanges, fault rocks, weathered rocks, tills, and colluvium. He is the developer of the bimrocks web site and edmedley.com, his personal/professional website.
Dr, Medley has experience evaluating geotechnical/geological engineering vulnerabilities and the causes of civil engineering failures, and has provided testimony for attorneys, insurance companies, contractors, and municipal clients. Projects include investigation of major landslides, rockfall hazards, expansive/collapsing soils, tunnel failures, coastal erosion, sinkholes and other ground movements in California, Nevada, District of Columbia; Hawaii, Guam, and Papua New Guinea.
Dr. Medley has authored/co-authored about 50 professional contributions, and presented about 260 professional and academic lectures, Short Courses and MCLE Credit courses. He was the 2009 Richard H. Jahns Distinguished Lecturer n Engineering Geology, awarded by the Assoc. Environmental and Engineering Geologists (AEG) and the Engineering Geology Division of the Geological Society of America (GSA). During his tenure he presented 85 Jahns Lectures to universities, professional associations and consultants in Canada and the USA.
