Hello 🇫🇷
I’ll be doing a mini-sabbatical in the lab of the amazing @clairewyart.bsky.social at the ICM in Paris. If you study motor control, spinal cord biology, evo/devo of behavior, let me know if you’d like to connect!

Hello lab!! It’s been six weeks of shutdown, so much chaos and loss. But today, I am deeply happy to feel a slice of normal, to see my team and our community, and do some science

🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity!
We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have:
(1) more corticospinal neurons (CSNs)
(2) better hand dexterity
(3) more dexterous climbing, which is linked to CSN number🧵

Does anyone have favorite colors for color blind friendly fluorescence images on a black background where the overlap combinations of 3 colors are important?
Magenta/cyan/yellow overlaps are difficult to distinguish (lots of white)
Thank you!

Despite some ups and downs at NIH, we do have an open position for a postbac and are considering candidates.
Our work is at the intersection of neuroscience and AI, and we aim to understand how the brain's densely connected recurrent networks operate. 🧪
