I have mostly published in atomic physics but I serve on Ph.D. committees in all areas, including high energy physics, cosmology, and condensed matter physics. There is no particular pattern to my research; instead I try to help solve puzzles that my colleagues come up with in their work. My current work illustrates this: I am working on the lineshape function in Doppler-free spectroscopy at low pressures, and my next seminar talk will be about magnetic monopoles in Yang-Mills theories.
