We develop theoretical concepts and computational models - mechanobiology, matrix mechanics, nano- and energy- materials. Tweets by group members. @CEMB_STC
1/6 We built a sequencing-informed polymer model that integrates STORM, Hi-C, and RNA-seq to reveal how HC domains — especially their boundaries —regulate gene expression during drug treatment, microenvironmental changes, and cell fate transitions. doi.org/10.1038/s41467-025-5…
6/6 🤝 Huge thanks to @ShenoyLab, @Melike_Lak, and @rp_mccord for the collaboration, and @CEMB_STC, the NCI MetNet - @NCIDCB! This work highlights the power of interdisciplinary science.
A new joint theory/experiment paper led by @ZeGongGreg just appeared in Nature Communications! We show how wave-like dynamics of immune cell podosomes arise from the coupling between chemo-mechanical signaling and actin diffusion. @CEMB_STC@PennEngineersnature.com/articles/s41467-0…

What balances the size of heterochromatic domains in our cells? @ShenoyLab et al explore the interplay of methylated histones, acetylation, and RNA polymerase II-driven supercoiling. Check out the sophisticated model led by Aayush Kant on @NatureCommsnature.com/articles/s41467-0…
Last day of the wonderful GRC on Signal Transduction by Engineered Extracellular Matrices #GRCSTEEM organized by Shelly Peyton and @kumarlabucb started with a session on multiscale modelling, with discussion leader Vivek Shenoy and first speaker @davidodde
Our findings reveal how chemo-mechanical environment cues such as changes in cell extracellular matrix stiffness affect not only the availability of epigenetic regulators but also the mechanosensitive binding of heterochromatin to the nuclear lamina.
New preprint on integrating biophysical computational modeling with high-resolution imaging to predict how epigenetics and chromatin-lamina interaction energetics regulate the size and shape of lamina-associated domains (LADs)! biorxiv.org/content/10.1101/…
By observing the size and shape of LADs via high-resolution STORM imaging by our amazing collaborators @Melike_Lak @HeoLab and @MauckLab, we can quantitatively extract the biophysical parameters - epigenetic reaction rate and chromatin-lamina affinity.
We theoretically show that the size scale of LADs is dictated by epigenetic reaction rates. On the other hand, LADs could be either discrete bead-like shaped or elongated and spread-out along the nuclear lamina depending on the strength of chromatin-lamina interactions.
