Dear Visitor,

I'd like to welcome you to my homepage dedicated to my professional life as an observing astrophysicist. I work on the centers of nearby galaxies, trying to observe and understand the immediate surroundings of the supermassive black holes (SMBH) that lurk there. Many of these SMBH actively accrete material from their surroundings creating "bright fireworks" that can be observed all throughout the electromagnetic spectrum.

Here you will not only find all relevant information about me and my research but I will also post once in a while interesting information I encounter during my work.

Please feel free to contact me in case of questions or directly comment on my entries!
