Ph.D. candidate at Edge Lab @USC | dancer. Pop gen & comp bio, with some ancient DNA hopefully. Meet my Chinese name 刘君健 (Liu Junjian)

[Sasha Gusev @SashaGusevPosts]

James Lee and @DamienMorris have an interesting perspective paper out describing "some far-reaching conclusions" about the genetics of intelligence. This type of "where are we now" paper is very fun and more people should write them! So, where are we now? 🧵

My paper about type I error rates in Qst/Fst comparisons is now published in @GeneticsGSA. Check it out here: https://t.co/oDjSlNbac7

[Doc Edge @DocEdge85]

New work from my lab, led by graduate student @janisl98. Janis studied type I error rates in Qst/Fst comparisons (1/n, link to preprint below)

In this preprint with Arun Durvasula, we discuss how there is no evidence for a bottleneck in the panmictic ancestral population of humans ~ 1 million years ago, as was suggested by Hu et al in Science last year

It was recently reported that Africans experienced a sharp, severe bottleneck around 900kya and that this signal is absent in non-Africans. Here, we present evidence to show why this is likely a statistical artifact:

Excited to share this new preprint with @spence_jeffrey_ and @DocEdge85 in which we developed a method to infer demographic history and mutation rates from millions of genomes, and applied it to gnomAD v4 data. Read on for a brief thread!

Second preprint from my group today---this one is led by @feriel_ouerghi_ . In this one, we discuss a previously proposed method for building forensic likelihood ratios from sequencing reads (1/n)

[Doc Edge @DocEdge85]

Two new preprints from my group today---this one was led by @Dandan_Peng with an assist from Obadiah Mulder. Dandan benchmarked a bunch of leading ARG-estimation methods with respect to a specific goal (1/n)

[Joshua G. Schraiber @jgschraiber]

I'm excited to share this new preperint with @mwpen and @DocEdge85 about the unifying mapping approaches within and between species https://t.co/DOYLfRUHoB

Eugenic movement and scientific racism: past, present, and future #TAGC24

panelists: Katrina Claw, Nathaniel Comfort, Steven Farber, Daniel HoSang, and @Jazlyn_Mooney

[Xiran Liu @Xiran_L]

Second time at #TAGC24/PEQG!
Presenting a poster tonight (785T) on my PhD work with @NoahARosenberg on mathematical properties of allele-sharing dissimilarities (and how they explain phenomena observed in human population-genetic data)!

Trait differences
Q_{ST} and F_{ST}
Details can deceive

(Janis Liu, "Error rates in Q_{ST} vs. F_{ST} comparisons depend on genetic architecture") #sciku #evol2023 @janisl98

[Janis Liu @janisl98]

So happy to have my first talk and make new friends at #evolution2023 !

[Feriel Ouerghi @feriel_ouerghi_]

The Edge Lab absolutely killed it at #evolution2023. So proud! @janisl98 @Dandan_Peng @ObadiahMulder @DocEdge85
