Major contributions are in the field of pyrometallurgical technologies for minerals processing, iron-, steel-, and ferroalloy-making. Areas of research include thermodynamics, kinetics and mechanisms of metallurgical reactions; properties of molten metals and slags; reduction, smelting and refining processes, environmental issues in pyrometallurgy. In 2005-2009, 32 papers were published in international journals; research funding exceeded $3.5M; 7 PhD projects were completed.
