My real name is Christian Hupfer too and I am a former Astrophysicist, but I quit the university and research after I've obtained my PhD (German "Doktor rer. nat.").
You can contact me by mail: firstname.lastname@example.org -- or via contact form on my website.
Nowadays I work as a teacher of Physics and Mathematics at a "Berufliches Gymnasium" near my beautiful region of Black Forest in Baden-Württemberg in Southern Germany, the pupils/students are basically at the age of 16 up to 20 years old and will graduate with A-Level ("Abitur/Matura") and may study at the universities after that.
All of my worksheets, class tests and books/articles are generated via LaTeX - I use it since 1997.
I am the author of following packages
They can be found on CTAN and on TeXlive as well.
I am aware that I could have gained more reputation and badges, but I answer basically unsexy questions about macros, tables and ToC related stuff, so my reputation and badge count is quite low compared to many others.
Since school lessons take place from about 8 o'clock in the morning up to 16 o'clock in the afternoon, I can't be at my computer around that time and answer questions here -- I can't sit in an office and grab reputation -- that explains my low reputation/badge count as well.
But I am the number 25 who got the [Epic] badge ;-)
Sad but necessary addition
Since some users misbehave here according to their style of feedback or not accepting answers (not only mine, answers of other users as well) I've started a personal blacklist of some users who won't get help be me again. Sorry, but this seems to be necessary.
And I dislike capricious users switching the tick to another answer although that answer is not really better than the previous accepted one.
- If a user is a
non-accepter, I will probably not answer -- not getting feedback (either in comments or by votes) just sucks!
- If an answer by me gets no upvotes I'll delete it rather -- it's apparently of no use to others.
