I do research at the intersection of physics and philosophy. My main areas of study include the foundations of quantum mechanics, the classical limit, field theory, general relativity, thermodynamics, and formal methods in mathematical physics. I am also interested in the philosophy of probability, the philosophy of time, the philosophy of mind, the history of physics, and logic.

I founded and organize the Foundations of Physics @Harvard workshop series.

I completed my PhD in the Department of Physics at Harvard University, where I currently serve as Lecturer and Co-Director of Graduate Studies. I am also a Faculty Affiliate with the Harvard Black Hole Initiative.

Harvard Physics 19: Introduction to Theoretical Physics
A self-contained, historically inflected course on theoretical physics for undergraduates who are new to the subject. The course provides a first-principles treatment of the foundations of analytical dynamics, fields, thermodynamics, relativity, and quantum theory, together with coverage of the relevant mathematical methods and philosophical concepts.

Harvard Physics 137: Conceptual Foundations of Quantum Mechanics
An undergraduate philosophy/physics course on the history, structure, and interpretation of quantum theory. The course covers the century-long effort to resolve the mysteries at the heart of the theory, a story that features fantastical notions like parallel universes, pilot waves, quasi-probabilities, alive-and-dead cats, and spooky action at a distance. The course also addresses relevant questions in philosophy, including debates over metaphysics, instrumentalism, scientific realism, determinism, epistemology, and the meaning of probability.

Harvard Physics 210: General Theory of Relativity
A graduate-level course on general relativity, covering the equivalence principle, differential geometry, spacetime curvature, the Einstein field equation, the Newtonian limit, orbital mechanics in the solar system, experimental tests, gravitational waves, black holes, and cosmology.

Harvard Physics 232: Advanced Classical Electromagnetism
A graduate-level course on classical electromagnetism, covering the Maxwell equations, boundary-value problems, multipole expansions, electrodynamics, radiation, scattering, macroscopic fields in matter, special relativity, gauge theories, coherent states, magnetic monopoles, and superconductors.
