I did my PhD in Madrid with Antonio Garcia-Bellido. The problem I tried to tackle back then was already growth control in imaginal discs. I learnt there that, to understand development, we have to focus our work at the level of single cells.
I then did a postdoc with Herbert Jäckle in Göttingen. In the lab of Herbert many of us really were confronted with what is to be a scientist. I also learnt a great lot of molecular biology. Then I started my group in the Max-Planck Institute of molecular cell biology and genetics in Dresden. Our initial focus was on the Cell Biology of Development: endocytosis, signaling, morphogens.
Then we started to collaborate with the Jülicher group from the MPI of Physics of complex systems. Since then, our strength is to combine developmental molecular biology, Cell Biology and Physics. Finally we moved to Geneva in 2006 where we continue with the same focus.
