His primary research interests are in the physical metallurgy of welding, focusing on a better understanding of weld phenomena through simulation, phase transformation analysis, advanced characterization, and on evaluation of weldability and service performance of welds in advanced alloys. He has contributed towards clarification of metallurgical phenomena related to major weldability problems experienced in the oil and gas, petrochemical, and power generation sectors. His research has been supported by US federal institutions and by more than forty companies from the US, UK, Canada, Germany, France, Sweden, Belgium, Austria, Brazil, Japan, and South Korea.
