Mengyi Zhu
About
Dr. Mengyi Zhu completed his undergraduate studies in Metallurgical Engineering at the University of Science and Technology Beijing (USTB), China, in 2013, followed by a master's degree in the same field from RWTH Aachen University, Germany, in 2017. He earned his doctoral degree in Metallurgical Engineering in 2021 from the Norwegian University of Science and Technology (NTNU), Norway. His Ph.D. research focused on silicon purification through acid leaching and slag refining techniques. His current research interests include slag science and engineering, computational simulations of metallurgical materials, machine learning for metallurgical applications, and sustainable ferrous and non-ferrous metallurgy for carbon neutrality.
