Biography: 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. Currently Dr. Medley is an independent Principal Consultant, performing his work through an association with Terraphase Engineering in Oakland California – February 2020 Terraphase CV is available here.

Recent consultations include a geological engineering reconnaissance of damage resulting from the October 2006 Hawaii earthquake; the retrieval of the invaluable Forbes Collection of unique Hawaiian cultural artifacts from lava tube burial caves; the evaluations of the stability of high rock slopes in chaotic rock masses; and, consultations on Hawaii and California landslides. Dr. Medley has contributed to over 50 publications, many of which are available at this website. Other contributions have focused on the seismic performance of rock block structures and the use of 3-D stereo photography in geopractice.

Dr. Medley has presented over  350 lectures and Short Courses. He was the 2009 Richard H. Jahns Distinguished Lecturer in Engineering Geology. He is the Summer Session Lecturer of an undergraduate Engineering Geology course at the University of California at Berkeley. He has appeared in over a dozen TV documentaries featuring failures, landslides, sinkholes and Franciscan Complex melange; and investigation of the 1995 Sea Cliff Incident in San Francisco.

Additional details of Dr. Medley’s professional background are available at his geopractitioner.com website. He provides stories and snapshots from his unusual career path at edmedley.com, his personal website. He has written on the considerable value in geopractice of 3D stereo imagery; and, developed a webpage describing the use  of ordinary digital cameras to take stereo photographs, and means to process the images and view them in 3D.
