Enjoying a mash-up of biophysics and development biology with plenty of cytoskeleton fun in the Grill Lab at MPI-CBG Dresden. Interested in climbing, outdoors and raising two decent human beings.

πŸ”¬βœ¨ For #IWD2026, we’re highlighting the voices of #WomenInScience!

In our short interview with Dr. Anna Czarkwiani @aniaczark.bsky.social shares what might surprise teenagers about a career in research and the skills that shaped her journey.

Spring PhD recruitment round @crick.ac.uk is now open and we have a project on offer: www.crick.ac.uk/careers-stud.... If you have a background in maths or physics and are curious about patterning and growth in biology this could be the project for you! Please help us spread the word πŸ’₯

Arittri's amazing finding that our old friend Lifeact can make actomyosin flow in the opposite direction, change chirality and flip left and right in the C.elegans worm.

In our latest preprint we show that Lifeact::mKate2 can reverse the chirality of active torques in the actomyosin cortex. This results in cortical flows with opposite handedness during left-right symmetry breaking, leading to the formation of situs inversus worms.

The Lab of Stephan Grill at MPI-CBG has finally made it to Bluesky and we also have a brand new homepage: grill-lab.org
Check it out.

Transport kinetics across interfaces between coexisting liquid phases

Paper alert!πŸ§ͺ
We derive a theory that underpins interface resistance with a physical foundation and look at how it changes droplet growth and recovery kinetics! Awesome collab with @bosste.bsky.social Tyler Harmon @hymanlab.bsky.social @m-pol.bsky.social and Frank JΓΌlicher @mpipks.bsky.social 1/4

Thanks as well to everyone who helped start this new part of the Grill lab, @stephangrill.bsky.social Adrian Lahola-Chomiak @arjun-narayanan.bsky.social Teije Middelkoop, Patrick Breier and all the support from our Veterinarian Katrin Reppe at the @mpi-cbg.de.

And in case you wonder... the eggs came from @jeromegros.bsky.social together with great knowledge from him and his lab especially @aurelienvilledieu.bsky.social. Thank you very very much!

What started with many quail eggs and put me on stage in a chicken suit has now resulted in a preprint www.biorxiv.org/content/10.1...
Microsurgery with human eye-lashes, laser ablations, great analysis and insightful theory from @neipel.bsky.social told us more about avian L/R symmetry breaking.

An active torque dipole across tissue layers drives avian left-right symmetry breaking Unlike in mice, frogs, and fish, left-right (L/R) body axis formation in avian embryos does not arise from the chiral beat of cilia. Instead, a counter-clockwise tissue rotation around Hensenβ€² node, t...

And thanks for everyone involved, especially @aurelienvilledieu.bsky.social and @jeromegros.bsky.social for sharing their expertise as well as @neipel.bsky.social Adrian Lahola Chomiak and the rest of the Quail Team who joined me in this adventure.

Here is what I have been up to in the lab of @stephangrill.bsky.social together with @neipel.bsky.social and many others.
Intrigued by avian left right symmetry breaking we found that a tissue-scale active torque drives chiral flow and requires mechanical coupling to the underlying tissue.

Live imaging and functional characterization of the avian hypoblast redefine the mechanisms of primitive streak induction In birds and mammals, the formation of the primitive streak, the hallmark of the primary axis and site of gastrulation, is thought to occur when an anterior displacement of the hypoblast (visceral end...

🚨New preprint
Glad to share my postdoc work on the role of the hypoblast in primitive streak induction! Discover how live imaging observations led us to revisit the molecular mechanisms governing embryonic axis induction
Thanks to @jeromegros.bsky.social and all co-authors!

How are single-molecule dynamics influenced by phase separation? What happens if these molecules undergo chemical reactions as they often do in biomolecular condensates? What if they are driven out of equilibrium?
