Currently a PhD Student in Computational Fluid Dynamics with a BSc in Mathematics. Programming either for my course or just little stuff because I can.
Further I am a dedicated hobby photographer - some of my work is available on Artflakes: https://www.artflakes.com/en/shop/detlevcm
A free basic guide to photography written by me is available at: https://detlevcm.wordpress.com
