Excited for this to be out officially! It was a great team effort and has a lot of useful tidbits for studying isoform function. www.nature.com/articles/s41...
Cas13d-mediated isoform-specific RNA knockdown with a unified computational and experimental toolbox - Nature Communications
The majority of human genes can produce multiple isoforms, but studying their functional relevance requires tools to target specific isoforms. Here, the authors develop a CRISPR-based exon-exon juncti...

Very excited that our most significant work, a collaboration w/ Dr. Can Cenik at UT Austin on translational gene regulation, was finally published in Nature Biotechnology in a dual set of studies:

Paper 1 -- an AI model trained to predict translation rates from mRNA sequences: rdcu.be/exN1l
Predicting the translation efficiency of messenger RNA in mammalian cells
Nature Biotechnology - A deep convolutional neural network model predicts the influence of the full-length mRNA sequence on translation efficiency.

New work from the lab trying to wrap our heads around the massive complexity of the human transcriptome revealed by long-read RNA-seq! Fun collab with Gloria Sheynkman. www.biorxiv.org/content/10.1...
Perplexity as a Metric for Isoform Diversity in the Human Transcriptome
Long-read sequencing (LRS) has revealed a far greater diversity of RNA isoforms than earlier technologies, increasing the critical need to determine which, and how many, isoforms per gene are biologic...

Please check out our new approach to modeling somatic mutation signatures.

DAMUTA has independent Damage and Misrepair signatures whose activities are more interpretable and more predictive of DNA repair defects, than COSMIC SBS signatures 🧬🖥️🧪

Spent the weekend reading the paper and sorting through the intuitions. Here's a visual guide and the main intuitions to understand the model and the process that created it.

Thanks to the FM4Science workshop at #Neurips for recognizing MolPhenix as best paper!

We had so much fun working on this with Puria (co-first author), @karush17.bsky.social, Frederik and co-supervised by Maciej and @dom-beaini.bsky.social

My conclusion: We should pay attention to train/test splits, not blindly follow standard benchmarks which are often very flawed in many applied ML areas, not hype up early results. We should be more collaborative, be generous with credit, give benefit of the doubt & be less adversarial
