I am a geopractitioner, with have 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. My unusual career path is described my personal website.

I  specialize 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 I am an independent Principal Consultant, offering my services and performing my work through an association with Terraphase Engineering in Oakland California – see my current Terraphase CV.   Sub-tabs to this webpage summarize my experience, professional contributions, and testimonials.  I am profiled at LinkedIn and ResearchGate. Testimonials from clients and colleagues are available on request.

As a geopractitioner I have 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. My projects experience 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. I am licensed/chartered/registered as an engineer and geologist in the USA, United Kingdom and Canada.

I have authored/co-authored over 50 professional contributions, and presented about 350 professional and academic lectures, Short Courses and MCLE Credit courses. I was the 2009 Richard H. Jahns Distinguished Lecturer in Engineering Geology, and and  have appeared in many TV documentaries as on-camera talent.

I once 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).
