Does protein dimerization always help targeting and dwell time on DNA? Not for a population! Spacing between DNA targets has big impact. Nonspecific binding and facilitated (1D) diffusion play a key role. Super proud of Mankun Sang’s work! doi.org/10.1101/2025.0…

Can sensing of membrane receptors be switched on at tunable threshold densities, without active processing? Proud to share this preprint led by the awesome Dr Foley, please check it out!
Sam Foley@PhysFoley

I’m excited to finally share our new preprint! Membrane-associated assembly processes like CME function as precisely-tunable, spatially targetable, robust on/off switches that don’t require energy at decision-time. #biophysics arxiv.org/abs/2505.17290

Very excited to share our Jeff (Anmin) PhD paper in collaboration with @Mejohnson81 and Phil Robinson demonstrating that Dynamin 1 undergo Dimensional Reduction: (1) recruitment to the membrane and (2) clustering, to make endocytosis happen. nature.com/articles/s4146…

Having diverse subunits in the complex helps expand the solution space. Automatic differentiation is a super cool method for optimization in large parameter spaces, thanks Spencer!

Excited to share our latest paper: no matter how stable the macromolecular assembly, kinetic traps can always be avoided by exploiting nonequilibrium protocols. awesome effort by Adip Jhaveri and former undergrads Spencer and Yian! pnas.org/doi/10.1073/pn…

@Nicolas_Fawzi @TheLHSeries thanks Nick! You may not remember but you were the one who I asked about the methyl group and who was, perhaps reasonably, appalled.

Want to work on biological physics at Johns Hopkins? (OK, or other areas of physics which I accept are also interesting). We have a prize postdoctoral fellowship, with competitive pay, some independent research budget - Dec. 1 deadline academicjobsonline.org/ajo/jobs/25522

The 2024 Biophysical Society meeting will be in Philadelphia. The abstract deadline is just about two weeks away. We have the BPS Lecture by @CarolynBertozzi and an exciting program by @TheVillaLab and Ibrahim Cisse. And the dance is back!

Excited to share our preprint where we 'discover' kinetic protocols for macromolecular self-assembly of highly stable complexes biorxiv.org/content/10.110… Awesome grad student Adip Jhaveri and former undergrad Spencer Loggia, automatic differentiation is a cool method!
