Moin! Jan Forbrich here.
I'm an Associate Professor at the Centre for Astrophysics Research, University of Hertfordshire, an External Research Associate at the Centre for Astrophysics | Harvard & Smithsonian in Cambridge, MA, and I'm a long-term visitor at the University of Oxford, closer to home. Well, currently I'm in the home office anyway...
