Research Interests

I'm generally interested in bridging the gap between prediction and decision-making, especially in the context of the institutional separation between model designers and decision-makers. I'm also interested in safe statistics, imprecise probabilities, and possibility theory.

Previously, I worked on studying the calibration properties of learning to defer (L2D) systems [ICML'22], extending L2D systems to allow for multiple experts [AISTATS'23], and studying the out-of-distribution behavior of L2D systems (in preparation). I also collaborated on a project on the test-time adaption of L2D to new experts [AISTATS'24].
