Edmund (Ed) Medley, Ph.D., PE, CEG, D.GE, F.ASCE has over 35 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 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; Canada, Hawaii, Guam, and Papua New Guinea.

Dr. Medley has authored/co-authored about 50 professional contributions, and presented about 230 professional and academic lectures, Short Courses and MCLE Credit courses. He was the 2009 Richard H. Jahns Distinguished Lecturer in 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. He has appeared on about a dozen TV documentaries as on-camera talent. He is licensed/chartered/registered as an engineer and geologist in the USA, United Kingdom and Canada.

Other Information:

I am  profiled at LinkedIn:

I have developed four web sites:  (and an earlier site, for  internationally-accessed resources on bimrocks;, a professional portal; and a personal/professional site.

I have created a webpage on the use of  stereo photos in geopractice. (BTW: the pahoehoe lava and leaf header image to this web site is an anaglyph  stereo image – use ordinary red/cyan stereo glasses to see 3D).

I have had an unusual professional career. If you are interested in how I got to be who and where I am, and have a few minutes to wander the world, then you may enjoy my lively vitae. (There’s a  pun there).
