Designing peptides/proteins to program biology! 🧬💻🧫 Assistant Professor at Duke | Co-Founder of Gameto and UbiquiTx | MIT SB, SM, PhD
Could we accelerate the discovery of the next GLP-1R agonist? 🚀 Here, we introduce PepTune, a multi-objective guided discrete diffusion model that generates target-specific peptides, while optimizing their therapeutic properties! 🪐

So excited to have Christian (@machine.learning.bio) join us at Duke!! 💙 We're building such an amazing AIxBio community with @rohitsingh8080.bsky.social, @alextong.bsky.social, Phil Romero, and others. ESPECIALLY in all things bio-based language models! 💻 🧬 Come join us in Durham! 😈
Two major life updates:

- I'm moving to Senior Applied Research Scientist in Digital Biology at NVIDIA (Jan '25)
- I'm starting a new lab at Duke as Visiting Assistant Prof (early '25)

Both roles focus on tackling hard problems in biological machine learning through collaborative research.

Surreal! 🤩 With co-founders Martin and Dina, we started Gameto in 2020 with just a silly graph theory algorithm I developed to predict TFs that could differentiate ovarian cells. 💻➡️🧫 Now, little Mia is here with the tech that has grown out of that work. 🐣 So proud!! 🥰

Alright new BlueSky friends, need some advice! 💡 I’m teaching my Generative Models (pLMs, graph models, diffusion, etc.) class at Duke next semester, and want to mix it up! Question: should I do theory on the board ✏️+ live coding 🧑🏾‍💻, or pre-prepared slides 🖥️ with annotated code snippets?

New RFDiffusion-for-peptide (RFpeptide) paper from @gauravbhardwaj.bsky.social and team at @uwproteindesign.bsky.social! 🌟 Beautiful binding data on 4 highly-structured targets (pLDDT > 90)! 🙌🏾 Not too confident this would work on highly disordered targets, though. 🤔

I’m curious to see how all of the new AF3 mimics perform. 🧐 My lab’s been installing them on our servers, and faster inference and ease-of-use are key for us. Boltz-1 has an early lead, but nothing beats a good frozen pLM with a structure trunk! 😅 Bc accuracy to the PDB isn’t the best metric. 🤷🏾‍♂️

Hi new followers! 🥰You may know me from Twitter as the sequence-first, pLM guy — hope you will continue to follow my lab’s work! 🥹 While you’re here, check out my lab’s new preprint on delivering pLM-generated degraders via LNPs to degrade cytosolic β-catenin in vivo! www.biorxiv.org/content/10.1...
Programmable protein degraders enable selective knockdown of pathogenic β-catenin subpopulations in vitro and in vivo
Aberrant activation of Wnt signaling results in unregulated accumulation of cytosolic β-catenin, which subsequently enters the nucleus and promotes transcription of genes that contribute to cellular p...

SaLT&PepPr is published in
Communications Biology! Here, we fine-tune the ESM-2 pLM to identify peptidic binding sites on target-interacting partner sequences. We fuse these "guide" peptides to E3 ubiquitin ligases to degrade disease-causing proteins! Take a read! :) www.nature.com/articles/s42...
