We are delighted to welcome Dr. Rakesh Chatterjee to our lab from today! He will be working on the project related with phase separation kinetics far-from-equilibrium.

Welcome, Rakesh! 🥳

Our recent paper has been published in ACS Nano!
The collective force scales linearly with the number of kinesin molecular motors driving a swarm of microtubules. Thousands of kinesin can work together cooperatively!

Spatial control of adhesion proteins is crucial for cell collectives. Tricellular junctions (TCJs) represent the example. We found gel-like condensation of a TCJ protein stabilizes its accumulation even in tissue dynamics, ensuring molecular recruitment and epithelial remodeling.

Dr Tzer Han Tan @tzerhan29 from UCSD visited us @palmiopas @AcadSinica in late-March! We, with a colleague here, hosted his seminar and discussions with PIs. We learnt a lot from his talk on their beautiful works on odd active matter. Thank you Tzer Han for such a wonderful day!

We thank Prof. Masaki Sano for his interesting talk on topological defects and organoids in soft matter systems at #IoPcolloquium.

[Hiraiwa Lab - Theoretical Physical Biology Group @tpbghl]

Last week, we invited Prof. Emeritus Masaki Sano (UTokyo), ex-boss of Tetsuya @HiraiwaTetsuya, and organized official colloquium and interaction sessions at IOP-AS @palmiopas :

We all learned a lot. Thank you very much, Sano-sensei, for the wonderful time!

[PALM labs @IOP AS TW @palmiopas]

Also, two from us @palmiopas @AcadSinica , Keng-hui herself and Tetsuya Hiraiwa (@HiraiwaTetsuya ), delivered the talks in the symposium.

and it was successfully concluded!

Congratulations on the great success, @KenghuiLin1 🥳🎉

Ryota Sakamoto invited Dr. Kevin Chen from Yale U to our institute @palmiopas early this month. We learnt a lot from his seminar at IoP on their multi-approach studies on behavioral dynamics and information flow! We also enjoyed the discussions with him. Thank you, Kevin!

[Tetsuya Hiraiwa @HiraiwaTetsuya]

Prof Makoto Sato from Kanazawa U visited us @tpbghl @palmiopas last week and had very interesting seminar on cellular tiling mechanism! Visitors for another workshop here, Profs Okuda @MechgenLab (NanoLSI) Hatakeyama (Science Tokyo) Hayakawa (KIT), also joined using this chance.

[Tetsuya Hiraiwa @HiraiwaTetsuya]

Our joint workshop MALA2025 at Keio U has successfully concluded! I appreciate all speakers from Taiwan and Japan, and Suzuki-san, who worked very hard as the organizer local-side, and all participants for stimulating and lively discussions and building new friendship networks🎉

[PALM labs @IOP AS TW @palmiopas]

We had a seminar by @SShimobayashi today! He gave a wonderful talk covering various topics in biophysics and experimental/imaging technologies on biomolecular condensates. We learned a lot and enjoyed his inspiring presentation and exciting discussions. Thank you again, Shunsuke!

[Shunsuke F. Shimobayashi @SShimobayashi]

Many thanks to Hiraiwa-san for the kind invitation to this wonderful institute in Taiwan!　@tpbghl

[Hiraiwa Lab - Theoretical Physical Biology Group @tpbghl]

We, with @KeitaKamino @NasuLab_IBC Dr Sakamoto, are inviting Prof Shunsuke Shimobayashi (@SShimobayashi) from CiRA, Kyoto U, to here @palmiopas @AcadSinica. Tomorrow, he will give a seminar at IoP on their great experiments on intracellular condensates! Thank you, Shunsuke!!!

[Tetsuya Hiraiwa @HiraiwaTetsuya]

We, with Prof Ryo Suzuki (Keio U), are excited to announce the upcoming international workshop “Multidisciplinary Approach to Living and Active Matter Systems”📢
