Key arguments & positions
- Argues models should be tested by the public who are affected by them, not only by the company that built them.
- Holds that bias bounties and structured red-teaming produce evidence that internal review does not.
- Argues accountability needs institutions and funding, not good intentions from individual teams.

Papers & key writings
Her main output is applied — red-teaming exercises, bias bounties and public evaluations — rather than a body of papers, so her positions above come from those programs and her public talks.
