Kort presentation
My main research interest is the fundamental interaction between X-rays and small molecular systems, which I use to probe the electronic structure of atoms ans molecules - the building blocks of out universe.
I am also interested in developing instrumentation for science, primarily for soft X-ray spectroscopy.
Biografi
Ever since I started my Ph. D. studies I have been interested in isolated atoms and molecules, that is matter in the gaseous phase as well as developing instruments for performing new science.
As a Ph. D. student I developed a new type of spectroscopy called XETECO, for the studies of gaseuos species. This is all well described in my thesis here.
Then, as a Post Doc I worked together with Catalin Miron in the finalisation of the PLEIADES beamline at the synchrotron SOLEIL in Paris. This beamline is also ment for studies of gaseous species.
When I had finished my Post Doc I continued my interest in advancing science through building new equipment - this time at Uppsala University where I have been building the HELIOS laboratory which is an HHG laboratory for studies of dynamics in matter.
At the moment I keep driving my main interest in studying fundamental interactions between X-rays and atoms and small molecules using soft X-ray spectroscopy. In order to do this I make use of national and international large scale facilities such as MAX-IV and the European XFEL.
