My work primarily concerns the interpretation of quantum mechanics. The question of interpretation asks whether quantum mechanics is capable of providing a consistent description of reality. To answer this question, one must carefully examine the most paradoxical features of quantum theory. Examples of such features include the possibility of macroscopic superpositions (e.g. Schrödinger’s cat), the apparent collapse of the wave function when a measurement is performed, the apparent randomness of events in nature, the apparent nonlocality exhibited by entangled systems, etc. Many physicists and philosophers have tried to understand such phenomena within orthodox quantum mechanics. Others have suggested that quantum mechanics must be revised if we are to make sense of them. This is a lively contemporary date. A project which delves into some aspect of it will deepen the student’s understanding of quantum mechanics and of what it is telling us about the nature of reality.

My own research has focused in large part on a particular interpretation of quantum mechanics: the many worlds interpretation. I have recently published (in collaboration with Lev Vaidman) on the topic of how this interpretation can help us make sense of the apparent randomness of events in nature. This would be a natural topic for an interested student to work on. However, I am interested in working on effectively any issue regarding any interpretation of quantum mechanics.

Students who work with me are typically juniors or seniors who have already had some exposure to quantum mechanics in previous courses, and have an interest in the foundations and philosophical implications of quantum mechanics. Projects can be arranged based on any level of student availability (1 credit or more). The goal of such a project will be to produce a paper that could be published in a peer-reviewed journal. The student will typically write several drafts in the lead up to this. The first is a literature review. The next is a more focused paper aimed at developing an original thought, i.e., an idea, argument, or criticism, that might contribute to the relevant literature. The student will receive extensive feedback and suggestions for improvement, and will then rewrite their paper. This process will continue until the goal is reached.
