Oma esittely

Expert in chemical physics specialized in the analysis of surface and interface phenomena, with emphasis on (photo)catalysis and corrosion, utilizing synchrotron light mediated in situ and operando electron spectroscopy methods.

I completed my PhD in physics in 2013 from Tampere University of Technology, Finland. During my post-doctoral research, I visited Stanford University and SLAC National Accelerator Laboratory working for the Joint Center For Artificial Photosynthesis (JCAP) project in 2014–2015 and had a Postdoctoral Researcher post (Academy of Finland) in 2017–2020 both dedicated on research of photocatalyst materials for solar fuel production. At Tampere University, I have established research activities on artificial photosynthesis including setting up research methods (PEC, ICP-MS, GC) and test protocols to characterize photocatalyst materials. My current research as Senior Research Fellow is focused on atomic layer deposition grown TiO2 based coatings for artificial photosynthesis.
