I am very happy to share that I've started my new position @upcite.bsky.social and opened my lab @institutimagine.bsky.social 🎉
In the lab we will study how differences in X-linked gene dosage between the sexes affect fetal growth and survival and contribute to sex differences later in life 👩🔬🧪🧬🧫

Choanoflagellates — our closest animal relatives — form multicellular colonies in two ways: cell division AND aggregation.
This previously unknown "mixed multicellularity" suggests our animal origins are more complex than thought.

This week, we discuss a study from the lab of Dr. Trista North (@tristanorth.bsky.social!
It shows that #HSPCs expand while staying multipotent thanks to tightly controlled ROS levels regulated by developmental #mitophagy.
