My work runs through medicine, law and AI, and all of it comes down to evidence. Where a claim on this site can be checked, it links to its source.

I work across medicine, law, AI and teaching, and in each of them the part I care about is making a claim checkable. In clinical research that means every finding in a cohort traces back to the rows it came from, which for OASIS meant reconciling 27,731 source rows.
