One of the last papers from my postdoc with @aspuru.bsky.social is now out. Led by the tireless @gkwt.bsky.social, it investigates chirality in text-based generative models. Includes a nice simulation-based benchmark task for circular dichroism that I think could be useful to the community.
New paper out in PNAS Nexus!
Molecules aren’t flat — so why should our models be?🧬
Our latest work "Stereochemistry-aware string-based molecular generation,” explores how considering stereochemistry changes the way machine learning models design molecules.

Excellent Nobel Prize. My suggestion for next year: chemical engineering. Nobel himself was an engineer, and the prize awards achievements that "conferred the greatest benefit to humankind". Furthermore, the Prize should also be given to "improvements". When did that happen the last time?
Indeed! Great day for Aussie chemistry. Richard Robson's work is finally being properly recognised. Congratulations also to Kitagawa and Yaghi. #ozchem
