Postdoc position available!!! We are looking for a creative postdoc to develop independent research directions in tissue morphogenesis using embryos, stem cell/organoid systems, and quantitative imaging and/or biophysics. Here are the details: livejohnshopkins-my.sharepoint.com/:b:/g/person...

El Paso is my hometown, and my birthday happens to be this week. Please join me in donating to Annunciation House (annunciationhouse.org). They help migrants, immigrants, and refugees in El Paso. More recently, they've sheltered people released from ICE detention: www.elpasotimes.com/story/news/i...

Instructors include @akankshi.bsky.social, @nicolettapetridou.bsky.social, @dianapinheiro.bsky.social, @chloeroffay.bsky.social, & @streichan.bsky.social among others! 🐟

Seconded. If anything, it has never been a better time to be a biophysicist, a complex system physicists, etc…. And it is a bit sad that much of it now happens *outside* of physics departments (for good and bad reasons…)

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good. Stay free

Really excited to share our new paper in @nature.com! We uncovered how a physical instability of the cytoplasm coupled with the cell cycle drives cytoplasmic partitioning in early embryos #zebrafish #drosophila.

How can cells use information from neighboring cells to improve the spatial precision of morphogen patterns? 🤔 We show that cells can gain positional information by "talking" to their neighbors - how much depends critically on spatial correlations of the patterns. buff.ly/w56OUJT

Now published in @natcomms.nature.com! 🥳 👉 rdcu.be/eATn3 We developed image analysis tools to capture the nematic orientation field of 3D tissue surfaces. Tested on epithelial aggregates, zebrafish hearts, myoblasts on spheres & micro-vessels, we combined soft matter physics with exp. biology.
