🇲🇽 Scientist @saezlab in @emblebi studying the molecular biology of multicellular disease processes ⌾ @lcgunam @UNAM_MX @UF @UniHeidelberg alumni
Heidelberg, Alemania
Joined September 2015
Writing this piece has been quite fulfilling (and scary). I spent half of last year putting in order some of my thoughts regarding how to study multicellular coordination with single-cell and spatial data. If you are interested please read the manuscript below. 😊
How to link single-cell diversity and the emergence and maintenance of robust multicellular processes in developed tissues? 🤔 What can we learn about multicellular coordination in tissues from single-cell omics data? Read about our view: https://t.co/z5msHv5EgB

I'm thrilled to share with you that #visiumStitched led by Nick Eagles has now been published Our #RStats / @Bioconductor 📦provides a framework for stitching together multiple #Visium @10xgenomics capture areas together https://t.co/T5SIJjrKY2
bmcgenomics.biomedcentral.com
Background Visium is a widely-used spatially-resolved transcriptomics assay available from 10x Genomics. Standard Visium capture areas (6.5mm by 6.5mm) limit the survey of larger tissue structures,...
Is your tissue larger than a @10xGenomics Visium capture area? If you need to stitch together the images but also the gene expression data, check our new preprint describing #visiumStitched We also shared example postmortem human brain data (3 samples) https://t.co/sYMH2V10JE

As the philosopher Celine Dion once said: My heart will go on🫀🔬 We've expanded our multi-study heart failure reference and proposed new multicellular analyses to get the best from scell and bulk data, all of this while learning how cells cooperate and divide labor in tissues!
What are the key disrupted multicellular processes in heart failure? In our new work we combine 23 years of molecular data with recent single-cell atlases to draw a cross-study patient map. How did we navigate the heart failure space? 🧵⬇️ https://t.co/aRDqdQxC5j

"Several members of my faculty [told] me, 'You can't get a job at Berkeley without a Cell, Science or Nature paper'. These [same] people had gotten jobs at Berkeley without a [CNS] paper...We believe this to be true to an extent that's irrational" @mbeisen

And they cost ~1% of journal articles (~0.01% of research). So whatever you think of peer review (we need more vs less vs different vs none), supporting a mechanism that provides rapid and universal free access to knowledge should be a no-brainer

Preprint servers are a low-cost mechanism for providing free access to research findings, and can also significantly accelerate research itself by making results available immediately. This Perspec...
#Preprints are important and valued in (most) job and fellowship applications. Also, they are the best currency for exchange of information, feedback and proof of what we are doing with funding.

Posting a preprint only after your paper is rejected by a journal is not the way to do it..

"Peer review...for centuries the standard tool to determine an academic paper’s suitability for publication". https://t.co/G7kuGKxTa5 No. The term is only a few decades old and Nature itself didn't it routinely until the 1970s. 1/3

Nature - The publisher of Physics World and other journals is marking Peer Review Week 2024 by calling for more courtesy in the process.
