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!

Excited to preprint our latest work (w/ Drew DeHaas, Zhibai Jia, Leo Speidel) on using ARGs for demographic inference. w/ applications using data from 1000 Genomes Project. www.biorxiv.org/content/10.1...

🚨 Join us in Uppsala and the lab of @trstngnthr.bsky.social as a 2 year fully funded bioinformatics postdoc with all Swedish social benefits etc!🧪 The project involves modern and #aDNA 🧬 in humans and sheep 🐑 to study adaptation. Application deadline: Oct 21st www.uu.se/en/about-uu/...

I totally recommend this position on @trstngnthr.bsky.social lab. Great place to do science, and amazing people to do it with! #aDNA 🧪 www.uu.se/en/about-uu/...

We're organizing a new CARTA symposium this November 7 on "Ancient DNA: New Revelations"! We have an amazing lineup of speakers who will showcase the biggest discoveries in ancient DNA over the past 5 years - and offer a sneak peek of what's next. Mark your calendars and don't miss it!

How many chromosomes can an animal have? In our paper out now in @currentbiology.bsky.social we show that the Atlas blue butterfly has 229 chromosome pairs- the highest in diploid Metazoa! These arose by rapid autosome fragmentation while sex chromosomes stayed intact. www.cell.com/current-biol...

Excited to say we’re hiring 😊. We’re looking for a post-doc in ancient pathogen genomics to join our friendly supportive team in London at @ugiatucl.bsky.social. Start date January 2026. www.ucl.ac.uk/work-at-ucl/...

🚨JOB ALERT!🚨 Postdoc position at #CpgSthlm on Microtine Palaeogenomics! Join our deep-time genomics project, funded by @erc.europa.eu, and help us explore lemming and vole evolution using ancient DNA from fossils spanning the last 2.6 million years 🐭🦴🧬 Apply here: su.varbi.com/en/what:job/...

Thrilled to share our study sequencing genetic data from tropical mammoths 🏝️🦣. First DNA recovered from Columbian mammoths southern than USA shorturl.at/xjIvy. Thanks to all collaborators, you were key to this success! See below a fantastic note covering the paper by the great @rpocisv.bsky.social 👇

Are you interested in doing a PhD in Copenhagen? Interested in studying Neanderthals and Denisovans which live on in our genomes? Than you are more than welcome to apply to join my group starting Jan 2026 :) candidate.hr-manager.net/ApplicationI... Please reach out if you have any questions!

Also - come and get my job! Which I’m still partially doing, but someone needs to take up the slack/ allow me to send them to far flung locations to retrieve mysterious ancient samples. See the World*! *mainly Britain. crick.wd3.myworkdayjobs.com/en-US/Extern...

The @scilifelab.se ancient DNA unit is looking for an bioinformatician placed at Uppsala University. This is a great way to be part of diverse #aDNA research projects as a staff scientist with permanent (!!) employment: www.uu.se/en/about-uu/...

Oops - link appears to be broken. Try this: academic.oup.com/g3journal/ad...

Excited for this to finally see the light of day - new preprint from my lab, where we present a fast, accurate maximum likelihood tool to estimate population structure, called MULTICLUST. We extend the model of Alexander et al 2009 (ADMIXTURE) to multiallelic data. www.biorxiv.org/content/10.1...

#MetagenomicsMonday Analysis of aDNA from 1313 ancient human remains spanning 37k years revealed that the rise of infectious diseases coincided with animal domestication around 65k years ago, with disease spread intensifying during pastoralist migrations. www.nature.com/articles/s41...

Results of our (extremely long-term) side project with @amygoldberg.bsky.social and @jgschraiber.bsky.social out now in G3: doi.org/10.1093/g3jo... We benchmarked methods for estimating ancestry proportions under mapping bias and present an adjusted GenotypeLikelihood to mitigate its impact (1/2)

New in #GENETICS: Huang et al. describe biases in SNP & local ancestry heritability as functions of admixture history and the genetic architecture of the trait, clarifying their interpretation and implication for #GWAS & polygenic prediction in population admixture. Read more: buff.ly/1xB3Mpu

Re-upping this! @cegamorim.bsky.social and I are stoked to be offering this workshop. Do join us!

New preprint alert 🚨 The tiniest bone in the human body appears to have the best DNA preservation: "The mini yet mighty staples" www.biorxiv.org/content/10.1...

last day tomorrow to register for a talk/poster at Midwest popgen. Please RT(? is that what they say here?)!

Forty years after Svante Pääbo kicked off this extraordinary field of science, today sees report of the first whole-genome sequence of an ancient Egyptian (from 2855–2570BCE). Exciting work from @pontus-skoglund.bsky.social, @flinklinus.bsky.social, & co at @ljmuofficial.bsky.social, @crick.ac.uk.🧬🧪

Please register if you haven't already done so. MidWest PopGen is happening in August at the University of Minnesota (Twin Cities)—abstract deadline for talk: July 11th, and poster: August 1st. sites.google.com/umn.edu/mwpg...

Thrilled to see the latest work from the lab (@genscapelab.bsky.social) out in Current Biology! Congratulations @jaurban2204.bsky.social ! 🎉 Grateful to have had the chance to contribute to this effort.

Delighted to share that one of my major PhD projects has been published today in Current Biology. In this paper, we look into the genetic population structure and demographic histories of two populations in Sri Lanka: the Sinhalese and Adivasi [1/n]. www.cell.com/current-biol...

Very special thanks to the Adivasi and Sinhalese individuals involved in this study!!! They are a pivotal part of this study, and we'll engage with them again in outreach activities soon! [6/n] Special note: Some of the supplementary links are still being fixed by the journal!

This was a true-collaborative effort involving teams from Sri Lanka, India, and the United States. Many thanks to my PI Maanasa Raghavan, co-authors @eshabandyopadhyay.bsky.social , PhD, Anjana Welikala and other co-authors!! [5/n]

6 years, 1 dissertation, 1 amazing supervisor, endless caffeine, many smiles, a few tears — and one unforgettable hooding ceremony. #PhDone👩‍🎓📜 @UniversityofChicago @genscapelab.bsky.social

Our paper on the theoretical properties of SNP heritability in admixed populations is out in Genetics: academic.oup.com/genetics/adv... with @jinguohuang.bsky.social, @nicole-kleman.bsky.social , Saonli Basu, and Mark Shriver

“Genes and geography: understanding human genetic variation” by @jnovembre.bsky.social, second talk in this cycle of talks on Human genomics and Paleogenomics for a general audience. Tuesday 29th November 12pm Mexico City time/1pm central time/2pm est. colnal.mx/agenda/genes...

Posting on behalf of Shamil Sunyaev: Eimear(Vice Chair) and I (Chair) are organizing the 2025 Gordon Research Conference (GRC) on Human Genetics and Genomics, which will be held on July 6-11, 2025 in beautiful University of Southern Maine, Portland, Maine.

aDNA/aeDNA folks: tired of eyeballing hundreds of damage plots? I am excited to introduce AdDeam—a tool to rapidly generate damage profiles, cluster them, and spot outliers. Great for large sample sets or flagging modern contigs in ancient metagenomics assemblies. www.biorxiv.org/content/10.1...

Interested in a starting PI position at University College London to work on Genetics, Evolution or the Environment? My department has opened the call for expressions of interest for sponsorship of independent fellowship applications. www.ucl.ac.uk/work-at-ucl/...
