Professional Biography

Dr. Ryti is a biologist with broad interests in environmental statistics, chemistry, and toxicology. He has over 25 years of experience in basic and applied environmental problems, including ecological and human health risk assessment support to the Los Alamos National Laboratory, the Hanford Site, and other clients. These risk assessment projects have addressed environmental contamination over large spatial scales with multiple stressors, large and complex databases, and significant involvement of regulators, natural resource trustees, and the public. Randall has also assisted in the planning, decision logic, and statistical design of environmental data collection activities for Environmental Restoration sites at Department of Energy facilities (Hanford, Los Alamos, and Savannah River), Department of Navy Base Realignment and Closure facilities in California, and EPA-lead Superfund sites. For many of these projects, Randall developed cost-based statistical approaches that assisted the decision-maker in achieving an acceptable cost and risk balance.

Dr. Ryti holds a Ph.D. in Biology from the University of California San Diego and a B.A. in Biology from the University of California Los Angeles.
