Most of my research activities and publications are related to computational atomic physics. Earlier in my career I dealt with the calculation of molecular, atomic and nuclear structures, but more recently I focused on atomic and molecular collisions using primarily positron and electron projectiles. The production of cross sections for such phenomena is important in a variety of fields, from astrophysics to the study of Tokamak plasmas.


Since 1985 I am a member of the York University Graduate Program in Physics and Astronomy, supervising graduate students in computational atomic physics. Together with Professor Allan Stauffer I have an NSERC research grant for the study of "Electron and Positron Impact Collisions with Atoms and Molecules" (current grant until 2020).
