About

Kejiang Li in Vienna.

I am a Full Professor at the School of Metallurgical and Ecological Engineering, University of Science and Technology Beijing (USTB). My academic journey began at USTB, where I earned my bachelor’s degree in metallurgical engineering in July 2012 and my Ph.D. in July 2017. During my doctoral studies, I had the privilege of conducting research at the University of Toronto, Canada, supported by the China Scholarship Council (CSC) (2015–2016).

I joined USTB as an Associate Professor in July 2017 and was promoted to Full Professor in July 2021.

I also serve as an Associate Editor of the Journal of Sustainable Metallurgy.
