Research

Research on ultrafast and high-intensity lasers in atomic, molecular, and optical systems. Experimental and theory work includes semi-classical and quantum systems interacting with light and developing new laser science technology. Applications include 21st century x-ray sources, high-power lasers, modeling complex dynamics, and experimental apparatus for precision high energy and relativistic measurements.
