So well deserved Fiona!

I owe this “career award” to everyone who has been part of @hassanbraindevlab.bsky.social over the years ❤️

I am grateful and excited to receive the Humboldt-Forschungspreis (Humboldt Research Award) from the @humboldt-foundation.de I look forward to inspiring interactions with this amazing scientific community. Thank you to Prof Robin Hiesinger for the nomination and the award committee for selecting me.

It was areal pleasure to visit and exchange with colleagues about the beautiful science being done. Thank you for having me!

Thank you for the invitation. Really looking forward to the visit.

Julien Pigeon and colleagues show how conserved processes can be fine tuned to result in species-specific patterns of brain development. Thanks to @alexbaffet.bsky.social @boyanbonev.bsky.social @neurogenesis-i3s.bsky.social for a great collaboration
👇🏽

Looking forward to this exciting meeting

I may starve to death before I am able to graduate in Gaza My only dream is to take the tawjihi exam so I can continue my education. Is this too much to ask?

One can only hope that history will judge harshly all those who are complicit in or remain silent in the face of genocide

Israel is destroying the subsistence of Gaza's population, from agriculture to fishing More than 95% of farmland has been damaged or lies in areas inaccessible to farmers, as the Palestinian enclave suffers from famine.

There is only one name for that: this is a crime against humanity. Israel is governed by monsters.

While I applaud Europe taking a step to fund bringing scientific excellence to Europe, the ERC’s current success rates at 10% for Europe based scientists is statistically at lottery levels. The total ERC budget should double across the board aiming at doubling funding rates.

Fantastic opportunity for neuroscience research.

@maheandria.bsky.social and I challenge the notion of a static and deterministic definition of a (neural) cell type and argue for its replacement by a multi parametric probabilistic definition in this perspective
