What I'm working on

Updated April 2026.

• Region embeddings for ontology entailment (subsume) -- 15 geometries, GPU training, EL++ losses.
• Entropy estimation from finite samples (fingerprints) -- Good-Turing, Chao1, Pitman-Yor, VV bounds.
• Flow matching on Riemannian manifolds (flowmatch) -- torus, sphere, SO(3).
• Writing about floating-point precision, passphrases, and the unseen species problem.
