This page is an abstract of my career background. For more information see my professional website:


Dr. Edmund (Ed) Medley, Ph.D., PE, CEG, D.GE, F.ASCE has over 40 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. Dr. Medley is experienced in 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. He is licensed/chartered/registered as an engineer and geologist in the USA, United Kingdom and Canada.

Dr. Medley has authored/co-authored over 50 professional contributions, presented over 350 professional and academic lectures, Short Courses and MCLE Credit courses. He was the 2009 Richard H. Jahns Distinguished Lecturer in Engineering Geology, a distinction awarded by the Geological Society of America and the Association of Environmental and Engineering Geology for career achievements as a Geological Engineer and Engineering Geologist.

He has three web sites:– which provides resources on bimrocks;, his professional portal; and a site with personal writings and images. He has also developed a webpage on how to take 3D  stereo photos with digital cameras; process them;  and, use them in geopractice.
