My research addresses issues in philosophy of physics, philosophy of science, and philosophy of probability.
My research focuses on the foundations of statistical mechanics and thermodynamics, and is primarily aimed at accounting for the success of statistical physics. I am currently addressing questions like: why do isolated systems away from equilibrium spontaneously approach equilibrium? Why do they then remain in equilibrium for incredibly long periods of time? Why do temporally-asymmetric equations, such as the Langevin equation, the Fokker-Plank equation, and Boltzmann's equation, accurately describe the behaviour of systems whose underlying dynamics are symmetric under time-reversal? What are statistical mechanical probabilities? And, how exactly is thermodynamics connected to statistical mechanics? I am also currently trying to resolve what is known as the measure zero problem, which, in a nutshell, involves justifying why we are entitled to neglect sets of measure zero in the application of certain theorems relevant to statistical physics.
Another aspect of my research examines scientific modelling, with an emphasis on toy models and the role they play in physics. I am addressing questions like: what are toy models? How are they used? How are they related to other scientific models? What is their representational status? And, what do they tell us about the world?
I am also interested in the philosophical foundations of probability theory, Bayesian approaches to confirmation, decision theory, and climate science.
