Check out the perspective my lab wrote with @freudlab.bsky.social. We provide our perspective on recent work describing the structural basis of chromatin-based base excision repair!

See our paper “Mechanism of trinucleotide repeat expansion by MutSβ-MutLγ and contraction by FAN1”. Using biochemistry, we show how DNA incisions by the MutLγ nuclease can lead to expansions, and how expansion is prevented by FAN1. Well done Issam and Valentina! www.nature.com/articles/s41...

The final piece of my postdoctoral work in the @freudlab.bsky.social was recently published! Quite amazing what this small little repair polymerase can do to fill 1-nt gaps in chromatin. www.nature.com/articles/s41...

🔊There's still time to register for the #EMGS webinar: An Applied Genetic Toxicology Career in the Pharmaceutical Industry with Zhanna Sobol on April 8, 2025 at 12:00 PM EST! Register Now: emgs-us.org/event/AGTCPI...

I am extremely proud to see our work about Hepatitis B now published in @cellpress.bsky.social From basic research to identifying the key step of infection & a potential first drug for curing this devastating disease. This has been an incredible journey.🧵 www.cell.com/cell/fulltex...

My lab is looking to hire a Postdoc to study mechanisms of DNA repair in chromatin using biochemical, biophysical, and structural biology approaches! Feel free to share with anyone you think may be interested. jobs.virginia.edu/us/en/job/R0...

Our Pathway to Independence programme aims to support postdocs going on the job market in 2025 with training, mentorship, profile-raising and networking opportunities. Apply by 31 Jan 2025: https://buff.ly/3VJGgDC #DevBio #StemCells🧪

The Weaver Lab is officially open today…Let’s see if we can fill up this empty lab space!

Is chromatin ordered or disordered? It all depends on the linker DNA length. Check our latest work with Mike Rosen and Sy Redding. We explore how changes in linker DNA length (as small as 1 bp) fine-tune chromatin structure, between order and disorder, and the properties of chromatin droplets

Our preprint from earlier this year on the oxidation-induced mutational landscape in human cells was just published! www.nature.com/articles/s41... I’m still amazed how much chromatin structure impacts oxidation-induced mutagenesis. Our cryo-EM contribution in this work provides a glimpse into why!

a short and sweet paper in which we use 3D STED and Micro-C analysis to show dramatic changes in large 3D chromatin structures in quiescence. www.biorxiv.org/content/10.1...

www.biorxiv.org/content/10.1... incredible study from Huabin Zhou and the Villa & Rosen labs -- a blueprint for mapping human chromatin with cryo-ET. The future of chromatin structural analysis in situ has arrived.

Today was the last day in lab for @tmweaver.bsky.social. We enjoyed lunch and gave him a 3D print of his first cryo-EM structure. Tyler's era was marked by incredible science, friendship, fun, collabs, and cats! He will do amazing at UVA running his own lab. We will miss you buddy #gogetem 🥹

Super excited to share our latest paper led by graduate student Mariia Mikhova! She used single molecule live cell imaging to dissect the kinetics of DNA break repair by non homologous end joining. We estimate the NHEJ pathway can repair up to 1000 breaks per minute! www.nature.com/articles/s41...

Happy to celebrate Brittiani Schnable's PhD work on thymine DNA glycosylase! www.nature.com/articles/s41...

Our paper on the strange ATP-dependent chromatin remodeler Smarcad1 paper is out and freely accessible. Differential regulation of its many activities by phosphorylation. Congrats to Briana and @nhoitsma.bsky.social 🧪https://www.sciencedirect.com/science/article/pii/S0021925824023950?via%3Dihub

Time to introduce myself! Incoming Assistant Professor at UVA-SOM. Interested in chromatin structure and DNA repair. Here is some of my final work in the @freudlab.bsky.social, where we determine how 1-nt gaps in the nucleosome are filled during DNA repair. www.biorxiv.org/content/10.1...

New DNA repair/genome stability work by our @icrlondon.bsky.social colleagues, led by Peter Martin in Wojciech Niedzwiedz’ lab. Check it out!
