Performance of Sequential Markovian Coalescence Methods when Populations are Structured https://www.biorxiv.org/content/10.1101/2025.10.09.681379v1
Take a look at my first preprint as a first author!
We analyse the effect of population structure in SMC methods and find two systematic biases that have indeed extra information about the population! We model the nature of these biases and find a link with the isolation of the population and Fst.

Rosalía, un nom que difícilment es posarà de moda
A Catalunya hem passat de 600 Rosalies a la dècada dels anys 50 a menys d'una desena en l'actualitat

It's the first human WGS study in Sudan. We uncover one of the strongest selection signals to date, pointing to post-admixture adaptation to malaria in Copts. Huge thanks to all co-authors. @aidaandres.bsky.social @jgarcia-cal.bsky.social @ebosch1972.bsky.social

Don't miss this study on selection using a Catalan cohort of Spanish Population! Catalonia is a region in the north of the Iberian Peninsula with a rich history of recent migration from all the Spanish geography. They made the most of the data with an historical context of popstructure!
I am delighted to share with you some new insights into the selection processes that shaped the Spanish population!
