Marcel Haas Welcome to my website! On several places you are supposed to find some info about me, my work, my hobbies, and... No, I think that's it.

In the navigation bar on the right you find the links to several parts of the website.

If you want to contact me, the contact details are below the navigation bar, if I didn't screw that up at some point...

So, have fun looking around. Questions, remarks or comments on the content or lay out of this website are always appreciated!

If you have some time left, don't forget to take a look at my puzzles website!

Short summary

In short, I work as a data scientist for health care insurance provider DSW. Here I focus on data analytics for fraud detection, customer satisfaction and other business problems. In a previous life I used to be a professional astrononmer. I did my PhD in Leiden and postdocs at the Space Telescope Science Institute in Baltimore (MD, USA) and at Rutgers University (NJ, USA). In several sections there is still some info on the science I did. I do still like it, obviously.

More about hobbys and my more personal life can be found here.
