What's New

I returned from Sydney to become the Chair of the Philosophy Department.  As a result I'm teaching only two courses, PHIL 146 (Philosophy of Physics) and PHIL 245 (Philosophy of Science: Environment).  The latter will be the first grad seminar on the environment in the Department.  See my teaching page for details. 

I'm still plugging away on my book on time, physics and psychology.  Meanwhile I've written a paper on the metaphysics of the quantum state, another on causal set theory and time (with my colleague Chris Wuthrich), and soon I'll begin thinking about black hole thermodynamics.  However, most of my recent efforts are directed at time perception.

In the near future I'll be speaking at the Old Globe Theater (San Diego) about Priestley's Time and the Conways, the APA (Pac Div), a conference on time at Chapman University, plus I'll be participating in a philosophy meets astrophysics workshop run out of the Carnegie Observatory and a philosophy meets cosmology workshop in Tenerife, Canary Islands.

About Me

I'm a Professor of Philosophy at UCSD.   I've been here since 2001. Previously I was in the Department of Philosophy, Logic & Scientific Method at the London School of Economics. Before that I obtained my Ph.D. from Rutgers University in 1997.

My main areas of research are:

I also have teaching interests in environmental ethics, among other topics.

I'm particularly interested in the intersection of time and modern science, the interpretation of quantum mechanics, the foundations of statistical mechanics, the metaphysics of science, and various issues about spacetime. Lately I've been working on a large book — tentatively entitled What Makes Time Special — that tries to show how our manifest image of time might arise in creatures embedded in a world like ours. I've also been working on phase transitions, the equivalence principle, the nature of the quantum state, and various temporal value asymmetries. I've published in philosophy, physics, and law journals — here is a (probably out-of-date) CV

When not working or with my wonderful family, I'm probably playing basketball or training for standup paddleboard racing (or hurt).
