Research summary > [Click to expand]

My research interests are in the philosophy of physics and the history and philosophy of science. By exploring the deep structure of our best scientific theories, I work to clarify how the world is structured, and what sorts of limits this structure imposes on human knowledge. Some examples of topics I can offer expertise and advice on include: - new developments in modern foundations of physics and why they matter - the history of science and our place in it - how scientific theories are confirmed and how they explain our world - the role and nature of mathematics as it is applied in science - special issues in understanding the nature of time, modern physics, and mathematical finance One central aim of my research has been to understand the direction of time and the passage of time. These are both pervasive concepts in science, appearing in everything from the motion of the planets to the behaviour of stock markets. But many puzzles remain. My work has sought to clarify what new lessons about time can be gleaned from our best theories of physics, as well as what general mathematical frameworks can be used to characterise time in the mathematical sciences.
