Tero Luukkonen is an assistant professor at the Fibre and Particle Engineering Research Unit, University of Oulu, Finland. He received his PhD degree in 2016 in physical chemistry at the Research Unit of Sustainable Chemistry, University of Oulu, Finland. Between 2010 and 2017, he worked in R&D positions at three start-up companies operating in the clean-technology sector. His current tenure-track assistant professor position is related to the development of high-value materials from inorganic side streams. His research interests include materials chemistry and waste treatment and environmental applications of alkali-activated materials in which areas he has authored more than 40 peer-reviewed articles.
