Short curriculum vitae

Since 2006 Beate Braun is at the IZW. After being a postdoc for 2 years she was hired for the position of molecular reproduction complementing the department reproduction biology with her biochemical expertise.
Research interests
  • Molecular and biochemical analysis of hormones and other molecular factors involved in reproduction (e.g. gamete maturation, fertilization, pregnancy maintenance)
  • recombinant expression of proteins important for reproduction and their functional characterization
