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 factors involved in reproduction (e.g. gamete maturation, fertilization and gestation)
  • Functions and physiological adaptations of specific cells and structural units of the reproductive system and their in vitro 2D and 3D culture
  • Recombinant expression of proteins relevant for reproduction and their functional analysis
