Ulrich Hagen

Ulrich Hagen (February 21, 1925 – November 25, 2007), a German scientist, is one of the German pioneers in the field of molecular radiation biology.

Hagen developed analytical techniques that would allow an examination and analysis of various types of DNA damage. He was among the first German radiation biologists to become aware of the important role of DNA repair in endpoints such as mutagenesis, aberration formation, cell death, and carcinogenesis.
