Biography

I have been a professor of experimental solid state physics in the WIhuri Physical Laboratory, Department of Physics and Astronomy, University of Turku since 2012. I got my MSc in 1994 in University of Turku and continued towards PhD as a Academy of Finland research assistant. I defended my thesis on YBCO thin films and nanoparticles in 1998. After that I worked as an Academy post-doc researcher in Risø National Laboratory, Denmark and in University of Turku. In years 2003-2009 I was an Academy research fellow at University of Turku. Since 2009 I have been a professor and the director of Wihuri Physical Laboratory. During years 2012-2017 I was also the head of the Department of Physics and Astronomy.  I was the vice-dean of the Faculty of Science in charge of teaching in 2017-2024 and have been the dean of the faculty since 2025.



Research
My research concentrates on flux pinning in YBCO thin films with artificial pinning sites and the theoretical modeling of these. We have found that the addition of columnar pinning sites into the films decreases the field dependence of the critical current density and changes the angular dependence. These changes depend on the size of the columns. We have also found that the crystallographic quality of the YBCO matrix determines the critical current density at zero field.

The other main topic is memristors made from GdCaMnO. Memristors can be used in e.g. neuromorphic computers and sensors to bring AI to the device itself and lower the energy consumption by factor of 1000. This means that the devices are not dependent on the cloud for computation and are therefore more robust in difficult environments, such as space or underwater. This research is funded by Business Finland and Jenny and Antti Wihuri Foundation.


Teaching

During the years I have taught many courses in solid state physics, superconductivity and magnetism at BSc and MSc level. Currently, due to the dean position, I teach only the BSc seminar course for physics students. I have tried to use active teaching methods, such as flipped classroom and pre-lecture questions, in all my courses. I have full teachers qualification in university pedagogics.
