I am currently on a two month research stay at the Vietnam Institute for Advanced Study in Mathematics (VIAMS) in Hanoi, Vietnam. Here I am working together with Prof. Do Duc Thuan and Dr. Phi Ha on singular switched systems with a focus on developing a comprehensive solution theory and stability characterizations. My former PhD-student Sutrisno has also been invited as guest researcher and is supporting our research efforts.

Today was my first day at the University of Groningen. I was able to set up my  new email-address and I also have a phone in my office (room 390 in Bernoulliborg), see my new contact-website.

I am currently in the process of moving from the University of Kaiserslautern (Germany) to the University of Groningen (Netherlands) from which I have received an offer for a permanent position as Associate Professor for Systems and Control within the Johann Bernoulli Institute for Mathematics and Computer Science. I will start in Groningen in November and as soon as I have a website with my new contact details, I will update my About Me page. My uni-kl-email-address will be valid until March 2018, so you can still reach me with the old email-address for a while.

The first five years in Groningen will actually be paid by my Vidi-grant which I obtained for my project proposal entitled “Analysis and Control of Switched Differential Algebraic Equations”. In the near future I will add a project page with more details about this project. To get a first idea, see the public summary in the list of Vidi Awards 2016, the corresponding press release of the University of Groningen, or the press release of the Faculty of Science and Engineering.

My name is Stephan Trenn and I am researcher in the area of applied mathematics, for more informations see the About Me page. You may also want to browse my publications, which can be filtered e.g. by keywords and coauthors. I also have profiles at Google Scholar, ResearchGate and ORCID.

Below, I will regularly post  news related to my research.

Finally, my Erdös number (see also here) is 4.

Due to my forthcoming appointment at the University of Groningen in the NETHERLANDS, my current research homepage domain with a top-level-domain “de” seems inappropriate and I decided to use the more neutral top-level-domain “net”. I will use this transition to relaunch my research website in a new design. It will take some time until I have transferred all my content and I will post the status of my migration here.
