Projects
Selected research themes that I am interested in. For a full list of papers, see publications.
Scalable Delphi
Scalable Delphi runs structured expert elicitation with LLM panels. The estimates track benchmark ground truth, agree with human experts on most quantities in three reproduced studies, and can be updated in minutes when the evidence changes.
Certified Training
Data poisoning is real and empirical defenses keep getting bypassed. We build methods that prove a model's predictions could not have been changed by any bounded poisoning of its training data.
