Xavier Roca-Rada, PhD

🇵🇹Our paper on Portugal's genetic history is now published in @GenomeBiology. We present the largest collection of ancient Portuguese genomes, with deeper analyses than our pre-print, revealing migrations, admixture and remarkable continuity doi.org/10.1186/s13059… @TeixeiraJoaoC

So happy to see this work on the genetic history of the Central Southern Cone published in @Nature 🌎🧬 Huge congrats to @javier_maravall and everyone involved!

🚨Proud to have co-authored this paper with an incredible team! We propose practical reporting standards to improve transparency, reproducibility, and data stewardship in paleogenomics 🧬🦴

Chapter 2 of my PhD is officially out !! science.org/doi/10.1126/sc…

New paper by Marina Bretos! Genetic ancestry, kinship, and funerary organization in the last Late Bronze Age communities of NE Iberia. A collaboration between @MPI_EVA_Leipzig , @IUCAunizar and @IBE_Barcelona nature.com/articles/s4200…

🚨 New paper! 🧬 We explore ancestry shifts, kinship ties & Mediterranean links at Mas d’en Boixos (Catalonia), from the Neolithic to the Iron Age. 👨🏻‍🔬A long journey since my master’s! Huge thanks to @cmpereirasantos Assumpció & Bastien! @ACAD_Research_ shorturl.at/B8TlB

Excited to share our new paper! We benchmarked the Twist Ancient DNA kit for in-solution enrichment. It’s cost-effective, robust, and shows no allelic bias, even when pooling libraries! @TwistBioscience @ro99i___ @ACAD_Research_ doi.org/10.1186/s13059…

🚨 Don’t miss the 1st HAAM-radio symposium: "Ethics in Human DNA Research" 📅 May 29 (next week!) 🕒 LA (7am) l Berlin (4pm) | Singapore (10pm) 📝 Register by May 28 🔗 shorturl.at/1VScZ

I’ve joined Bluesky and will be moving there! Find me at bsky.app/profile/xavier… 🦋

Great working with @Haarkotter on this project! Excited about the results of applying aDNA to forensic samples! 🦴🧬

🚨 NEW PAPER ALERT 🚨 From @shyama_mama and team @ACAD_Research_ academic.oup.com/bib/article/26…

@Dani_96RA @GREAB_UAB @cmpereirasantos Congrats!!🎉🎉

🚨News!🚨 Thrilled to share my first paper as first author, now published in #PLOSONE: "An easy-to-use pipeline to analyze amplicon-based Next Generation Sequencing results of human mitochondrial DNA from degraded samples" @GREAB_UAB @cmpereirasantos dx.plos.org/10.1371/journa…

@CurrentBiology From @DNATimeTravel, @XavierRocaRada, @ro99i___ and team using the Twist Human Ancient DNA panel “Optimised in-solution enrichment of over a million ancient human SNPs.” biorxiv.org/content/10.110…

Bringing you the 3rd series of HAAM-Radio Webinar! This time we’ll talk about Southeast Asian and Oceanian population. Don’t forget to register yourself to receive the zoom link.

Excited to be hosting this webinar on Ancient DNA with @DNATimeTravel and @XavierRocaRada . Come and hear all about their research. LIVE NOW linkedin.com/posts/adam-wer…

@ro99i___ 🥰❤️‍🩹

It's been so exciting to watch this project come to fruition!! Lots of incredible hard work from @XavierRocaRada ! Thanks for having me on board 😄 The Genetic history of Portugal from ancient human DNA 🧬🇵🇹👇

Thrilled to share our preprint on Portugal’s genetic history! 🇵🇹

@leorcooper @kristjanmoore @TeixeiraJoaoC Thank you for your feedback! Apologies for the citation oversight. Our info came from Huang et al. (2018), which identifies the macrohaplogroup in Ashkenazi Jews and other European and Asian populations. We’ll clarify this in the revised manuscript.

@kristjanmoore @TeixeiraJoaoC @XavierRocaRada Thanks for this comment— I agree, I’m not familiar with any evidence that this Y chromosome exists in any Jewish group. Ashkenazi Jews in Q all fall downstream Q-L245>Y2200, which is related to this Q branch well over 10,000 years ago.

Preprint alert🚨This one is special, as I am happy to share our latest work on the genetic history of my native Portugal! Led by postdoc @XavierRocaRada, we use aDNA to uncover dynamic interactions between migrant and local communities across millennia! biorxiv.org/content/10.110…
