On this page, you will find an overview of the presentations I gave to academic and non-academic audiences, colleagues and students. These presentations include a range of different talks at conferences, seminars and workshops. The presentations could be delivered as keynote speaker or intended to be published. Some presentations were based on papers and intended to be published, others were not. The overview is far from complete, but it present a fair insight into the range of my interest and engagement.
