I work for NVIDIA and help out at CMU, JHU and Stanford in an effort to make Bioinformatics Better. Everything I post is my personal opinion. You're awesome!

Pharmaceutical giant Roche announced it is launching a new large-scale “AI factory” with thousands of the latest Nvidia chips to accelerate the development of new drugs and diagnostics. Roche said the company has ramped up its AI capacity by purchasing 2,176 Nvidia Blackwell GPUs, which will be deployed across the U.S. and Europe. That brings its total GPUs to more than 3,500, which it claims is the greatest number owned by any pharmaceutical company. Roche, which made the announcement in conjunction with Nvidia’s GTC conference in San Jose, hopes to use that technological firepower to discover, develop, manufacture and commercialize therapies faster.

Introducing PerturbAI. Today we announced our emergence from stealth with the release of the world’s largest in vivo CRISPR data engine, interrogating the effects of thousands of genetic perturbations across 8 million cells throughout the whole brain. This dataset represents a new category of biological data: organism-level, circuit-resolved causal genomics leading to novel targets and therapeutics. By combining scalable in vivo CRISPR perturbation with AI, we model biological systems at unprecedented resolution and simulate therapeutic interventions before committing to expensive downstream development. We’re grateful to our collaborators at @NVIDIAHealth and @10xGenomics for helping make this landmark dataset possible.

Since it’s GTC week - good time to reintroduce what I do at @nvidia. I manage the investment portfolio of NVIDIA Ventures, working with startups across frontier model builders, techbio, robotics, AI infrastructure, materials discovery, energy, quantum and healthcare. I frequently draw on my training as a scientist and product manager for my job. My primary goal is to drive tech and ecosystem integration between NVIDIA and portfolio companies. Which can eventually lead to successful long term relationships. I am most interested in areas where AI translates into real world systems, especially in biology, robotics, and other scientific applications. More on here - nventures.ai

It's hard for me to contain my excitement for the work fo the Digital Biology Team @NVIDIAHealth #NVIDIAGTC this year. I can't WAIT for you all to see what we have been up to. I've got a detailed talk on Wednesday morning where I'll go through all the details on behalf of the team, but there will be lots to discover tomorrow and Tuesday too! nvidia.com/gtc/session-ca…

AlphaGenome: Decoding the dark matter of the genome with a unified deep learning model More than 98% of human genetic variation lies outside protein-coding regions. These "non-coding" variants can disrupt gene regulation in remarkably diverse ways: altering chromatin accessibility, shifting 3D genome architecture, modifying splicing, or changing expression levels—often in tissue-specific patterns. Yet existing computational models face a fundamental trade-off: either they capture long-range regulatory interactions (like distant enhancers) but blur fine-scale features, or they achieve nucleotide resolution but miss distal context. And most specialize in a single modality, leaving users to stitch together predictions from many separate tools. Žiga Avsec and coauthors at Google DeepMind present AlphaGenome, a model that sidesteps these trade-offs. It takes 1 megabase of DNA as input and predicts ~6,000 genome tracks—spanning gene expression, splicing (sites, usage, and junctions), chromatin accessibility, histone modifications, transcription factor binding, and 3D contact maps—at up to single-base-pair resolution. The architecture combines a U-Net backbone with transformer blocks: convolutions capture local motifs essential for splice sites and TF footprints, while transformers model long-range dependencies like enhancer–promoter interactions. Training uses a two-stage approach—pretraining on experimental data followed by distillation from an ensemble of teachers using mutationally perturbed sequences—yielding a single model that scores variants across all modalities in one pass. The results are striking: AlphaGenome achieves state-of-the-art performance on 25 of 26 variant effect prediction benchmarks, including a 25% improvement in predicting eQTL direction over the previous best model. It outperforms specialized models on their own tasks—beating SpliceAI-class methods on 6 of 7 splicing benchmarks and ChromBPNet on accessibility QTLs. Critically, the multimodal outputs enable mechanistic interpretation: for oncogenic mutations near the TAL1 gene in T-cell leukemia, AlphaGenome simultaneously predicts neo-enhancer formation (increased H3K27ac), chromatin opening, and elevated gene expression—recapitulating experimentally validated mechanisms. This points toward a future where interpreting non-coding variation no longer requires assembling a patchwork of specialized models. A unified framework that jointly predicts molecular consequences across modalities could accelerate rare disease diagnostics, guide therapeutic oligonucleotide design, and help prioritize variants in GWAS loci—moving us closer to truly reading the regulatory code written in DNA.
