Research Interest:

Theoretical atomic physics. Inner-shell ionization and energy loss of charged particles in matter. Development and improvement of the ECPSSR theory of K-, L-, and M-shell ionization that is widely used for comparison with x-ray and Auger-electron production cross sections; in particualr in PIXE analysis.
