Using novel experimental techniques coupled with mathematical modeling, Professor Argyropoulos has established a comprehensive knowledge base pertaining to the thermo-chemical principles that govern in-situ and interfacial reactions during alloying of molten metals. From his studies of fluid flow phenomena, he has also pioneered the development of an innovative sensor to measure for the first time, the magnitude and direction of velocities in high temperature liquid metals. Recognized by international honours and awards, this distinguished researcher has made substantial and sustained contributions to the Engineering Profession through his research achievements, his mentoring of young engineers, his communication of new knowledge to industry and his numerous activities within technical societies.
