New SPCG paper. With the Bokinsky lab (Milan Lacassin), Andrea Ripamonti modeled the competition for transcriptional resources. Our data and model jointly show how E. coli’s second messengers ppGpp & cAMP reshape gene expression globally. www.sciencedirect.com/science/arti...

New SPCG preprint in collaboration with the Amir lab We solve an accumulator model of cell division with noisy threshold and memory, finding a continuum of strategies from timer to adder to sizer and that extrinsic noise is essential to explain E. coli size fluctuations. arxiv.org/abs/2605.070...

Saddened to learn of the passing of Moselio "Elio" Schaechter—Distinguished Professor at Tufts, SDSU and UCSD—humanist and visionary leader in the fields of microbiology and scientific communication—mentor, friend, and inspiration to me and so many others Small Things Considered Big Things Achieved

Our work on optimal treatment in presence of cancer persisters is out today in @prxlife.bsky.social 🎉 Alternated drug-release periods may be an advantage due to dose-dependent transition rates and slow death of persisters journals.aps.org/prxlife/abst...

Optimal Treatment for Drug-Induced Cancer Persisters Involves Release Periods and Intermediate Drug Doses
Extending persistence modeling to drug-induced, dose-dependent cancer persistence reveals that strategic drug holidays and reduced doses can improve long-term treatment outcomes.

Just out on bioRxiv - spcg collab with Piel lab: growing mammalian cells use two independent systems — one controlling volume, one driving protein synthesis — to control macromolecular density. Together, they restore dry mass density homeostasis. www.biorxiv.org/content/10.1...

Spcg preprint with Bertotti lab and @litinice.bsky.social. It took >5y but proud to say it works—and we know why and how. μSeq infers mutation rates from deep sequencing of single clonal expansions, >10x faster than MALs. Validated in cancer organoids and in yeast. tinyurl.com/4jmk3tkh
