Teaching

I have teached and assisted in courses on Process Metallurgy and Industrial Engineering at the University of Oulu and at the Aalto University. However, my main form of pedagogical activity is the supervision of Doctoral, Licentiate, Master's, and Bachelor's theses in Process Metallurgy. The instructed theses cover a broad range of topics ranging from ironmaking via meltshop to hot rolling.
