Mika defends his 2nd thesis on Saturday!

Dr. Mika Lastusaari defends his thesis from the Faculty of Education, Department of Teacher Education on Saturday 10th of November at 12 o´clock noon in the lecture hall Educarium 1. His thesis is titled “Persistence in major in relation to learning approaches – Development of a questionnaire for university chemistry students”.

Amazing job and well done, Mika! We are thrilled that we’re going to have a two-times Dr. (or maybe Dr.Dr.) in our research group soon!

New face around: Anssi

We gained new addition as Anssi Peuronen joined us for his three-year post doctoral project (tutkijatohtori) from the Academy of Finland.

His current research is focused on developing metal-organic coordination cages that would be able to selectively bind anions. Anssi will be working closely with our other metal-organic chemists Ari Lehtonen, Pasi Salonen and Esko Salojärvi.

We hope that you have settled well and enjoy your stay with us.
