Description of Research

We are an experimental physics research group. We develop new tools and apply them to a wide range of problems we find interesting and important, including:

* precise tests of physical laws and symmetries;

* the search for rocky (Earth-like) planets around other stars;

* biomedical imaging, with a focus on pulmonary physiology and brain function;

* slow and stored light, with applications to quantum information and photonics;

* observational cosmology; and

* studies of porous and granular media.
