Our lab has some ongoing data driven/AI/ML in active matter projects that can be supported through postdoc.ucsd.edu/funding/schm.... if you are interested, or if you have some ideas of your own, feel free to reach out!

@tzerhan29.bsky.social et al show topological defects in cell traction forces underlie emergent chirality

They show pancreas derived organoids rotates as an active solid! bsky.app/profile/epim...

Largest Cohort in UC San Diego Program’s History Receives Hellman Fellowships Over 30 years ago, the Society of Hellman Fellows Program was founded at UC Berkeley and UC San Diego. The program awarded 10 Hellman Fellowships in 1995 at UC San Diego. This spring, 26 UC San Diego ...

Honored to be selected and join the 2025-26 cohort of UCSD Hellman Fellows! today.ucsd.edu/story/larges...

If you’re eligible for a Pew Latin American Fellowship, please reach out to Suckjoon Jun (Pew ‘13). We have ambitious bluesky projects planned for the next decade, backed by exceptionally strong funding, and we’d love for you to join us!

Looks amazing! Are these mitochondria

✨#FluorescenceFriday brings you a glowing Berghia stephanieae juvenile! This stunning sea slug is lit up with Anti-α-Tubulin 🟢, revealing the dense network of cilia that help it glide across surfaces. 🐌💫 Image taken by @Luiza-O-Saad.bsky.social

Always great fun to brainstorm at our UCSD monthly biophysics forum - let's bring the intelligence into active matter

Scientists Develop Simple Model for an Intricate, Ever-Evolving Cell Structure Scientists apply principles of math and physics to unravel the mystery of how the endoplasmic reticulum, an organelle vital to cellular life, constantly reshapes and reorganizes itself. As a second-ye...

Textbooks: cell is a bag of weirdly shaped stuff.

Reality: it's all moving & changing shape.

When two grids with a twist make a pattern exist, that’s a moiré. Listen to this week's episode of Quanta Science Podcast: podcasts.apple.com/us/podcast/e...

Very cool! What happens when you cut two wounds - do they waves interact?

Optical control of an excitable enzyme circuit for engineering dynamic cell shapes - Nature Physics Light-switchable enzymes hold great promise for mediating molecular activations in living cells, yet their full potential in realizing versatile controls in nonlinear networks remains unexplored.

Glad to see this work finally out. Happy to have played a small part in this project with teams @fakhrilab.bsky.social @physicsoflifelmu.bsky.social!

Ramin Golestanian (Oxford & MPI Göttingen) visited us and gave an inspiring informal seminar yesterday. 🙏🏻

Four #SPLASHY talks from the lab for #APSphysics March meeting next week at Anaheim, from starfish embryos to robotic active matter - looking forward! #ApsDsoft #ApsDbio #PRX_Life

#standupforscience at UCSD!

APS March meeting coming up: the fun starts Sun 3/16 with Squishy Science Sunday!

Exciting opportunity at @CZBiohub SF! Join us as an Optical Scientist developing cutting-edge light-sheet microscopy to map vertebrate development. PhD in Optics/EE/Physics preferred. #ScienceJobs #Microscopy #BioImaging 🧪🔬💻

Stand up for science! Happening this Friday 3/7 - look up for local events near you : standupforscience2025.org most campus nationwide will organize, join if you can, make our voice heard, repost, organize! #standupforscience

It was great visiting UMich Ann Arbor and Wayne State University! Many thanks to @surajshankar.bsky.social and Zhi-feng for hosting. Great interactions and lots of new ideas to try

@nigelgoldenfeld.bsky.social introducing @ucsd-biophysics.bsky.social to UCSD physics open house - welcome prospective students to sunny San Diego!

Schematic overview on how MicroSpit operates. It can split superimposed structures in fluorescent image channels by using a suitably trained AI.

Concrete example for how MicroSplit unmixes four superimposed structures.

Immagine you could image two cellular structures in the same fluorescent channel and still reliably get them separated afterwards…
What would you do with this?

Now… what would you do if that also worked with 4 structures at once? 👇 #MicroSplit #preview🧵

Congrats Claire!!

The big 4 of grant writing:
1. Credibility: The topic fits your expertise
2. Narrative: It's clear what is the problem, the solution, and why you’re the right person for it
3. Juicy details: Flex your mastery of the topic
4. The concept: You connect every part to the big question

Full house! Great way to end the quarter with Kinneret telling us about topological defects and biophysics of Hydra regeneration.
