What started as a PhD rotation turned into a wonderful collaboration with Noah Rosenberg ✨. (4/4)

We use phased SNP-STR reference data from 2504 individuals in the 1000 Genomes Project, with SNPs surrounding the CODIS STRs. When selecting SNPs based on characteristics such as MAF and distance to the STR, we find that ~1000 SNPs suffice for record-matching, a 10-fold reduction. (3/4)

Prior work has used around 10,000 SNPs for record-matching. In this project, we asked whether we can further reduce the size of SNP panels required for record-matching with STR profiles? Reducing the number of SNPs has important implications for privacy and cost-effectiveness. (2/4)

Existing systems for forensic identification rely on STRs, but future systems may eventually rely on SNP panels. Genetic record-matching could help this transition by enabling the matching of STR and SNP profiles using linkage disequilibrium between SNPs and STRs. (1/4)

We are excited to share GPN-Star, a cost-effective, biologically grounded genomic language modeling framework that achieves state-of-the-art performance across a wide range of variant effect prediction tasks relevant to human genetics.

Staff scientist position (computational):

I am looking for a computational scientist to join my genomics lab at Stanford. They should have an outstanding skillset in ML/statistical methods for genomic applications, postdoc experience and a strong publication record.

What a joy to work on exciting science AND do it with a great friend like @itskatelawrence.bsky.social! Check out her 🧵 on our recent preprint with @sbmontgom.bsky.social:

Excited to share my first PhD paper in the @sbmontgom.bsky.social lab with @tamigj.bsky.social (www.biorxiv.org/content/10.1...)! Standard QTL methods treat each gene independently. But what if a single variant regulates multiple nearby genes at once - what we call “allelic proxitropy”? 🧵 ⬇️
Standard methods are equivalent to a flashlight, looking at each gene independently. We combine signals from multiple genes, turning a floodlight onto the genome.

Modern GWAS can identify 1000s of significant hits but it can be hard to turn this into biological insight. What key cellular functions link genetic variation to disease?

I'm very excited to present our new work combining associations and Perturb-seq to build interpretable causal graphs! A 🧵

Thrilled to share the first paper of my PhD! It was so much fun working on this collaborative project from day one as a rotation student! Huge thanks @khoulahan.bsky.social, @lisemangiante.bsky.social, @crissotomayor.bsky.social, @cncurtis.bsky.social, Jennifer Caswell-Jin & the Curtis lab!

What do GWAS and rare variant burden tests discover, and why?

Do these studies find the most IMPORTANT genes? If not, how DO they rank genes?

Here we present a surprising result: these studies actually test for SPECIFICITY! A 🧵on what this means... (🧪🧬)

Specificity, length, and luck: How genes are prioritized by rare and common variant association studies
Standard genome-wide association studies (GWAS) and rare variant burden tests are essential tools for identifying trait-relevant genes. Although these methods are conceptually similar, we show by anal...

In a new preprint led by @TheNikhilMilind, we explored a fascinating paradox:
For many traits the number of duplications or loss-of-function (LoF) mutations is correlated with phenotype. Curiously, for most traits, the AVERAGE direction of LoFs and Dups is the SAME. Why?

Just posting this to #popgen
Here's a link to my notes on population & quantitative genetics:

Hoping to extend it more after the winter holidays, as I'm just finishing up teaching the undergrad version of class.

🧬 What are protein language models (PLMs) actually learning about biology? Our paper introduces InterPLM - a framework that reveals interpretable features in PLMs using sparse autoencoders, giving us a window into how these models represent protein structure and function.

I’ve decided to leave Scientific American after an exciting 4.5 years as editor in chief. I’m going to take some time to think about what comes next (and go birdwatching), but for now I’d like to share a very small sample of the work I’ve been so proud to support (thread)
