About & Contact

From 2009 to 2019 I was working in the south of Germany, first as a Post Doc, afterwards I moved to the analytical industry. Beforehand I did my PhD studies at the University of Hanover. Science was fun and still is, but during my Post Doc period, I got frustrated about funding systems. Too many projects that were designed extremely broad, too much political influence on funding as well as obsessive publishing of moderate studies disagree with my scientific expectation. Besides that I want to live in a stable professional environment without scientific nomadism from doctorate to an unlikely permanent position.
Since mid of 2019 I am based near Hanover, still working for my employer in the South.
In my present position, I am responsible for a team of analytical specialists which is working in a good balance between scientific and industrial demanding tasks. Our activities cover mostly sales support in the EMEA region, but also development and marketing support. Challenging tasks occur on a daily basis and require open and clear discussions to close projects successfully. Coordinating application tasks belongs to my duties as well.
Besides my professional life, my interests concentrate on my roots, history of Germany's coastal regions, Scandinavia, photography, geology and playing my guitar. I am investing an increased amount of time on the use of modern web technologies and their influence on the society.
Honorary, I am organizing the website of the lighthouse Kleiner Preuße.
