Excited to announce that this fall I'm starting my lab at the University of South Carolina! Our hybrid wet/dry lab will explore fundamental topics in animal evolution, looking at how different evolutionary processes combine quantitatively [pleiotropic conflicts, mutation bias, etc.].

Happy to highlight new findings by Vanesa Getseva and Lin Poyraz about the sources of variation in germline mutation rates among humans: www.biorxiv.org/content/10.6... Joint work with Anastasia Stolyarova and @ipsitaagarwal.bsky.social. 1/n

A sibling study of variation in parental mutation rates

People are born with variable numbers of de novo germline mutations (DNMs), depending primarily on the ages of their parents. To explore additional causes, we developed an approach to call DNMs from nucleotide differences between siblings in genomic regions inherited identical by descent from both parents. Applying it to whole genome sequences from 28,985 sibling pairs of diverse genetic ancestries present in the UK Biobank and All of Us datasets, as well as 2,330 trios, we identified >800K autosomal DNMs and characterized mutation phenotypes in 27,645 sets of parents. We found subtle shifts in the mutation spectrum but no differences in total DNM rates among genetic ancestry groups, or between smokers and non-smokers. Testing for associations between parental mutation phenotypes and their burden of loss-of-function and deleterious missense variants in a set of 180 DNA repair and maintenance genes, we discovered that disruptions in REV1 and LIG1 increase germline mutation rates, and thus that rare mutator alleles segregate in population cohorts. ### Competing Interest Statement The authors have declared no competing interest.

I'm excited to tell you about the most recent preprint in my lab, demonstrating that a conserved spindle matrix protein, NPP-21/TPR, is required for the stronger checkpoint in germline cells during embryogenesis in C. elegans

NPP-21/TPR is required for developmental control of spindle checkpoint strength in C. elegans https://www.biorxiv.org/content/10.64898/2026.04.13.718277v1

I defended my PhD 10 years ago today. That was the least remarkable thing that happened that day. Sharing something I wrote about it last year. Since then "the horrors persist but so do we." And with dignity.

love when there's an article about how life is sustainable in the superheated waters surrounding a hydrothermal volcanic fissure on the ocean floor and then like six paragraphs in you find out the author's parents are chemosynthetic bacteria 🙄
