The selection committee for this award was composed of representatives of the Association of Environmental and Engineering Geologists (AEG) and the Engineering Geology Division of the Geological Society of America (GSA).

50 years old, the AEG is an international, non-profit, scientific and technical association whose 3,000 members include geoscientists specializing in engineering geology, environmental geology, and ground-water geology as well as other professionals in affiliated fields such as civil and mining engineering, land-use planning, public policy and education.

Established in 1888, The GSA is a global professional society with a growing membership of more than 21,000 individuals in over 85 countries, and encourages the professional growth of earth scientists at all levels of expertise and from all sectors: academic, government, business, and industry.

The award was established in 1988 to commemorate Professor Jahns (1915-1983), who had an influential and diverse career in academia, consulting and government. Past Lecturers are well-known academics and geopractitioners.

Dr. Medley is an independent Consulting Geological Engineer. Between June 2005 and June 2009 he was a Senior Consultant in the Oakland, California office of  an international consultancy renown for innovative solutions to geoengineering and environmental problems.

Dr Medley started work in the Applied Earth Sciences in 1969, and now 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. He has an international reputation for his pioneering research into 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. (Most of his professional contributions are at freely available at bimrocks.com.)

Dr. Medley also 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 well over 150 professional and academic lectures, Short Courses and MCLE Credit courses. He is licensed as an engineer and geologist in the USA, Canada and the United Kingdom.

In 1978, graduating from the Univ. British Columbia, Dr. Medley was the first awarded of the Aro A. Aho Memorial Medal for Academic Excellence in Geological Engineering. He was the AEG Marliave Scholar in 1993, awarded for outstanding scholarship in Engineering Geology and Geological Engineering. He was the San Francisco AEG Section Membership Committee Chairman between 1991 and 1993 and the San Francisco Section Short Course Chairman between 1995 and 1996.
