Developmental origins of sex differences

Our research

Studying the genetic and epigenetic determinants of sex differences

How do males and females become different? How early are detectable sex differences established? How does the genome direct the male and female trajectories?

We study the genetic, epigenetic and transcriptomic components that drive sexual dimorphism in mammals from early embryonic development and across the lifespan.

Our values

“While timorous knowledge stands considering, audacious ignorance hath done the deed.” - Samuel Daniel (1562-1619)

We aim to do quality science in an environment that values curious, irreverent minds. We believe that the most creative thing we can do is to ask new questions. These drive the imagination and passion that are the raw material for designing elegant, informative experiments. These values generate an environment that unlocks each individual’s potential, while fostering teamwork and a culture of continuous learning.
