My Research

Hey there! I’m a historian and philosopher of physics taking a pluralist approach to issues in quantum foundations and physics education research. In recent years, my work has focused on the interpretation of quantum probability and issues of reduction and emergence in the relationship between classical and quantum mechanics.

My current project, Credence and Chance in a Pluralist Approach to Quantum Theories, develops novel technical results about the probabilities appearing in quantum mechanics that bridge and support several different interpretations of what that theory says about reality. The project also explores the utility of this pluralist approach for upper-level physics education, in collaboration with Rachel E. Scherr.

Everettian chance in no uncertain terms

We unify Everettian accounts of chance by focusing on the conditions under which branches are isolated.

Philosophy of Probability

Hypothetical frequencies as approximations

Hypothetical frequencies are great approximations (inexact descriptions of a target) but bad idealizations (separate models that bear analogies to the target).
