Very happy to share that I’ve been awarded a K99 Career Development Award from NIGMS for my work on MSH2-MSH6 and its role in recombination-mediated rearrangements.

Big thanks to my mentor, Wolf Heyer, co-mentor, Megan Dennis, letter writers, and colleagues.

Using #yeast, Yu et al show templated insertions at double-strand breaks in cancers arise from foldback mechanism involving microhomologies. Lack of RPA may drive this process, shedding light on cancer's genetic instability #CancerResearch #Genetics #DNARepair

‼️ Excited to share our new paper out now in @science.org ‼️

We describe a new tetrameric RAD51 paralog complex – XRCC3-RAD51C-RAD51D-XRCC2 – which caps the end of RAD51 filaments.

Happy to share our @narjournal.bsky.social paper on the mechanism of Dmc1 filament stabilization by Mei5-Sae3!

We show that Mei5-Sae3 can stabilize both active and inactive Dmc1 filaments, and that this is independent of the ATP hydrolytic cycle.

Mei5–Sae3 stabilizes both active and inactive forms of Dmc1 filaments independently of its impact on ATP hydrolysis
Abstract. In budding yeast, Dmc1’s recombinogenic activity is controlled by the meiosis-specific heterodimer Mei5–Sae3. Mei5–Sae3 is required for assembly

Among the anti-recombinases, FIGNL1 rules them all. So much that inactivating it brings BRCA2-deficient cells to life. Who is responsible for RAD51 loading without BRCA2/FIGNL1, check out the paper to find out! Great collaboration with @raychaudhurilab.bsky.social

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!

If anyone is hiring a technician, I’ve got a great candidate. I wish I could hire her myself! She’s got the grit, she knows how to hustle, and she does publication quality work. Lots of molecular biology, protein, and cell culture experience. Please DM me if you are interested.

I want to try something again at #ASHG25 this year: I'll block some time on Thursday and Friday afternoons to meet with trainees who would be interested to chat on any topic.

I did this last year and it was great to meet a whole bunch of new people, at all career stages!
