DegreePh.D., Material Science, University of Waterloo, Canada, 1971.
Current RoleMaterial Scientist, Nuclear Materials and Waste Disposition, assisting the U.S. Nuclear Regulatory Commission (NRC) in evaluating license renewal applications and certifying new reactors.
CapabilitiesExpertise in corrosion/compatibility and environmental effects on mechanical properties of structural materials in reactors and coal conversion systems; research on aging-related materials degradation in reactors.
- Argonne project leader: Preparation of technical guidance and review plan for license renewals of light water reactors (LWRs) for extended operation.
- Principal investigator: Experimentation and statistical modeling for predicting fatigue crack initiation in reactor materials; incorporation of environmental effects into fatigue evaluations; characterization of thermal embrittlement of cast austenitic stainless steels and estimation of their fracture properties in LWRs.
- Developer/manager: Investigation of cyclic crack growth, irradiation-assisted stress corrosion cracking, and radiation embrittlement of LWR components.
- Consultant: For the NRC, development of an experimental program on materials degradation for reactor pressure vessel internal components.
