Areas of Expertise

 

My research has always involved lasers and atoms.  For many years I used lasers as a tool to study simple atoms and molecules, including using light to actively manipulate atoms.  In particular I used lasers to cool atoms to ultra-low temperatures and then stick them together to form molecules, a process known as "photoassociation." Much of what my colleagues and I learned about atoms and molecules this way is summarized in a 2006 Reviews of Modern Physics article (see publication list). 

More recently I have used atoms as a tool for manipulating light.  The non-linear interaction between light and matter allows the production of a whole range of quantum states of light that are not accessible by classical optics techniques.  Among other things, we have explored various kinds of optical amplifiers that work near the fundamental limits set by quantum mechanics.
