Designing Synthesizable Ionizable Lipids with Generative Models
The math and the diagrams behind our synthesis-constrained discrete diffusion paper — discrete graph diffusion, scaffold conditioning, region-aware noise, and why every generated lipid stays synthesizable by construction. 99% valid, 62% novel, best candidate at 2× the training-mean predicted potency.

Generating lipids, not molecules
Everyone wants to point a generative model at ionizable lipids. It's harder than it sounds: the thing you're designing isn't a molecule, it's a formulated particle — so the model has to be constrained by makeable chemistry, formulation context, and the right multi-objective readouts.

The delivery problem everyone is solving is the wrong one
The field is optimizing reach and potency. The market pays for tolerable, repeatable dosing — a different, often opposing axis that the whole screening apparatus is blind to. Why that gap is the real frontier for AI × biotech.
