Short presentation
I have been in charge of the buildup of the HELIOS lab dedicated for time-resolved studies in the XUV domain, you can read more about HELIOS here.
In HELIOS I am involved in essentially all projects and also running my own projects for studies of isolated species (gas phase). If you are interested in what I am doing do not hessitate to contact me, either as a student or a researcher.
Biography
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 finalization 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. The HELIOS laboratory is described in some detail here.
At HELIOS I am involved in all projects, however my main interest still lies in the studiy of free atoms and molecules and dynamics in these systems.
