1/🧵 Can transcription factor condensate formation be explained without phase separation? Our new preprint introduces SPARK, a simulation tool that reproduces condensate behavior (clustering, fusion, FRAP) from diffusion & binding kinetics alone. Movie: 60 sec FRAP sim www.biorxiv.org/content/10.6...

Excited that our work on RNAPII clusters during development is finally in print today! Thanks to everyone who worked incredibly hard on this project and the community for their engaging (and fun!) discussion during each iteration. Please see the post below for details!

Super cool!

Come on join us! We are searching for the next technical associate to join our lab ~Summer 2026. This could be a great position for someone who is graduating this spring and is looking for 2 more years of research experience before starting their PhD: careers.peopleclick.com/careerscp/cl...

Delighted to have a contribution in this issue together with @eliasfriman.bsky.social

(1/3) Excited to post our updated pre-print! We show RNAPII clusters are simply collections of polymerase molecules stably engaged at single genes & cluster intensity is strongly correlated with txn output during Drosophila embryogenesis. www.biorxiv.org/content/10.1...

1/n: Excited to share our new preprint. We find that Dorsal transcription factor hubs exhibit gene-specific biophysical properties that tune transcriptional output. Read here: www.biorxiv.org/content/10.1.... Project was led by amazing graduate student Samantha Fallacaro (not on bsky)

1/n Excited to share our new preprint! Using live imaging in Drosophila embryos, we show that RNA Pol II clusters switch from sites of initiation to elongation during zygotic genome activation and that they are stably associated with an active gene: www.biorxiv.org/content/10.1...
