Dr. Kocher has extensive experience in areas of environmental health physics and assessments of dose and risk from exposure to ionizing radiation. He has special expertise in evaluations of dose and risk assessment models for regulatory and decision-making purposes, and he has written and lectured extensively on the issue of risk harmonization in regulating radionuclides and hazardous chemicals in the environment. Dr. Kochers work on assessing the biological effectiveness of different radiation types and their uncertainties was an important contribution to the development of the Interactive Radio-Epidemiological Program (IREP), and he was principal investigator on work for the Defense Threat Reduction Agency (DTRA) to develop improved models and methods of uncertainty analysis for use in dose reconstructions.
Dr. Kocher has served on several advisory groups for Federal agencies and on committees of the National Academy of Sciences (NAS) and National Council on Radiation Protection and Measurements (NCRP), including committees that produced an NAS report on A Review of the Dose Reconstruction Program of the Defense Threat Reduction Agency and committees that produced NCRP reports on Risk-Based Classification of Radioactive and Hazardous Chemical Wastes (Report No. 139), Approaches to Risk Management in Remediation of Radioactively Contaminated Sites (Report No. 146), and Performance Assessment of Near-Surface Disposal Facilities for Low-Level Radioactive Waste (Report No. 152). He also was a member of a committee of the U.S. Department of Energy (DOE) that produced a DOE Standard on A Graded Approach for Evaluating Radiation Doses to Aquatic and Terrestrial Biota. Dr. Kocher has been a frequent consultant to the International Atomic Energy Agency on issues of radioactive and hazardous chemical waste management and protection of the environment.
