Dr. Derek Martin first became internationally recognized as an expert on the geotechnical hazards associated with the storage of nuclear waste underground, a problem of considerable concern. In addition to Canada, he has advised programs in five other countries. Since moving to a university base, he has expanded his early interest in geohazards associated with dams, tunnels and landslides where he has also become an authority. His leadership of the highly successful Railroad Ground Hazard Research Program is particularly noteworthy. Dr. Martin ensures that his contributions influence professional practice through his approximately 200 papers, over 25 invited lectures and the training of numerous graduate students.
