Dr Turunen specializes in fluorescence microscopy of biomimetic materials    

Dr Turunen's research backround involves single-molecule catalysis studies of enzymes and synthetic catalysts using fluorescence microscopy, and development of advanced single-molecule detection schemes based on zero-mode waveguide (ZMW) metal nanostructures. His main research topic in the Rowan group at the AIBN is investigating mechanotransduction interactions between cells and extracelluar matrix (ECM). Part of his work is designing advanced fluorescence imaging and rheology facilities within the group that is required to measure cells response under applied stress in a controlled way and in high accuracy. His research further involves developing ZMW based detection schemes for single-molecule studies of single chain polymeric nanoparticle (SCPN) enzyme mimics. 

Dr Turunen received his MSc in Physics from the University of Eastern Finland in 2010. Searching for an interesting, multidisciplinary PhD project, he got interested in single-molecule fluorescence spectroscopy and started his PhD in the Molecular Materials group at Radboud University Nijmegen, the Netherlands, in 2011, under supervision of Prof. dr. Alan E. Rowan and Dr. Kerstin Blank. In September 2015 he continued in the same group as post-doctoral researcher. In 2017 he started as a Postdoctoral Research fellow with the Rowan group at the AIBN.
