The information on this page remains generally valid, but note that I intend to be absent from Physics and Astronomy through the school year 2013-2014.
I am also an Associate Professor in the Department of Physics and Astronomy at Carleton College.
I started at Carleton in the Fall of 2001, coming here most recently
Among the many reasons to aim for excellence in education is that it is vital to the long-term health of science. Of particular interest is the integration of research and education (see, for example, the Boyer report). I include references to current research in all my classes (even the introductory classes), and also like to work closely with students on projects as part of my ongoing research.
My research field is theoretical and computational non-linear dynamics, more broadly statistical physics. I am particularly interested in the quantum non-linear dynamics of systems that are chaotic in the classical limit, and in coherence and decoherence -- the impact of environmental noise and coarse-graining on these dynamics. While previous work was on fairly abstract issues, recent work has been done while working closely with experimentalists in atomic physics; other work has predictions about the behavior of fluid dynamical systems.
Since linear dynamical systems are a small subset of the set of all possible systems, we have to understand and control nonlinear dynamics to explore the great majority of all possible physical phenomena. Nonlinear and chaotic dynamical systems promise to continue as a source of fascinating fundamental and applied physics for years to come. Nonlinear quantum systems are even more interesting, and moreover underlie future technology.
I write a blog/professional journal entitled Confused At A Higher Level.
