Ad forthcoming, but I am hiring for a postdoc or staff scientist to advance related investigations of the virus-host conflict. This position is ~80-100% computational, but with opportunities for experimental work if desired. If interested, shoot me an email with your CV! Reposts appreciated! 15/15

The US built the greatest talent magnet ever, attracting the smart, skilled, and striving. They’d come to study, then stay and build things here, or leave with positive impressions and fruitful connections. Helped make the US wealthy and powerful. Then America chose to throw it away. And for what?

I'm giving a poster on MIMIC at #ISMB2026 today (C-211)! Drop by and chat with me about multimodal modeling for DNA, RNA, and protein biology. Inference code + checkpoints + sample data are all now available on GitHub/HuggingFace. github.com/PolymathicAI...

Introducing MIMIC: a new foundation model trained natively across DNA, RNA and proteins. MIMIC is multimodal and generative: it can use structure, regulation, evolution, and experimental context to infer missing biology or design new sequences. 🧵⬇️
Can we program a kinase like a switch? Inspired by natural autoinhibitory complexes, we designed miniproteins against active- and inactive-like conformations of Focal Adhesion Kinase. Depending on the targeted state, the resulting binders either activated or inhibited the kinase.

My go to example of this sort of thing is the study of weird thermophilic bacteria gave us PCR, upon which so much of modern biological research and its many applications (including drug discovery!) depend
People often think about risk as referring to (i): Can the project achieve its specific aims? But really what NIH should want is (ii): studies with low probability of huge long-term impact. Here, think of work on gila monster venoms (leading to GLP-1 meds) or bacterial immune systems (crispr)

AlphaFold database has entered the era of complexes. Together with NVIDIA, DeepMind and EBI, we use ColabFold, OpenFold and MMseqs2-GPU to predict ~31 million complexes (homo & hetro-dimers) resulting in 1.8 million high-quality predictions 📄 research.nvidia.com/labs/dbr/ass... 🌐 alphafold.ebi.ac.uk
You asked, we listened. Millions of AI-predicted protein complex structures are now available in the #AlphaFold Database. This spans homodimers from 20 of the most studied species, including humans, as well as the World Health Organization’s priority pathogens list. www.ebi.ac.uk/about/news/t...
Had a lot of fun working on this with Darius, Christian, and Rohit. We address the problem of unpredictable scaling behavior for PLMs -- with a simple 2-line drop-in replacement for ESM2, you no longer need to worry that a smaller model might end up performing better! 🧵⬇️
Protein language models don't scale reliably: bigger doesn't always mean better for embeddings. What if what you need from ESM-15B is already inside ESM-8M? Introducing Reverse Distillation, which flips the usual distillation script: small models anchor and decompose large ones
