I did my diploma in biology at the Institute of Biochemistry of the Justus-Liebig-Universität in Giessen.
In that time I did:
contribute some work for the book
Arbeitsmethoden der Biochemie
write a little program called "Counter" for the paper
A quantitative microtiter plate nuclease assay based on ethidium/DNA fluorescence.
work with M.Hahn for the paper
Semiautomated quantitative detection of loss of heterozygosity in the tumor suppressor gene p53.
Also there I did meet my wife for the first time - so that time was the most important of my life.
