Sasmito's research and educational efforts have focused on advanced multiphysics systems for sustainable minerals and energy extraction. He established McGill Mine Multiphysics Laboratory and his research has spanned a wide range of scientific and technological development for mine ventilation, heating, cooling, freezing and drying, geo-energy, thermal energy storage, artificial ground freezing, slurry, paste and particulate flow, rock-microwave and other multiphysics modeling in mining and energy extraction engineering. Dr. Sasmito has supervised more than 40 graduate students (M.Sc. and Ph.D.) and postdoctoral associates and has published over 180 refereed journal papers and more than 100 peer-reviewed conference papers. He was the recipient of the 2019 CIM-Bedford Canadian Young Mining Leaders Award, 2021 Principal Prize for Outstanding Emerging Researcher and 2024 Fellowship of Canadian Institute of Mining, Metallurgy and Petroleum.
