I have 40 years of experience and specialize in the field of physical metallurgy with specific knowledge in the areas of phase transformations, mechanical behavior and radiation effects. I have published on such topics as precipitation strengthening, radiation-induced precipitation, coarsening of precipitates, high temperature creep and fracture toughness of small specimens. I have testified 12 times on topics such as failure analysis, wear of surgical instruments and low-temperature creep of stainless steel.
