Research Field:

My expertise is the experimental study of light matter interactions and ultrafast opto-electronic technology. I have studied atoms and molecules in perturbative “multiphoton” and nonperturbative “strong” optical fields. Most recently, my interest is in probing the physics of atoms in “ultra” high intensity laser fields; light whose intensity is billions and billions of times more intense than sunlight on the earth. Such interactions compare to the most violent astrophysical events. New and exciting excitation processes occur in these high fields where v/c and B are not approximately zero and our common understandings are tenuous.

Developments in laser technology are greatly responsible for the newest insights into light-matter interactions. Within the past five years, this has involved advances in the control of the spatial and temporal characteristics of light.

I have also served on many committees and paper reviews.

Also important to me is the greater scientific community
