Research Interests

My research involves atomic and molecular collision science and work to extract basic understanding and quantum control of few-body microscopic systems based on a long-time experience with more conventional studies of correlated electrons and ions.Although the work is theoretical, my interest in these topics is largely motivated by the recent surge in experiments involving few-body molecular fragmentation and the full imaging of all the fragments.My research accordingly continues with two parallel efforts with (i) emphasis on reaction imaging while (ii) pursuing longtime workon collective Coulomb excitations. I continue to place strong priority on research relevant toexperiment. 

Besides various NSF funding over the years, my research has been supported continously by the DOE, Fundamental Interactions Office of Basic Energy Science, for over 30 years.

Teaching Interests

I'm a big fan of physics pedagogy involving symbolic computing and the author of the textbook Quantum Methods with Mathematica (Springer). I'm happy to share my Mathematica lecture notebooks upon request.
