My primary research has been in the area of computational atomic physics. This research has focusd on calculation of cross sections for processes in which one or two electrons are removed from atoms or ions. I have investigated photodetachment, in which an electron is removed from a negative ion, and double ionization by electron impact, in which two electrons are simultaneously released from an atom as a result of a collision with an energetic electron. Double ionization is an mportant process to study because it shows that electrons in atoms do not behave as independent particles, but rather have a strong correlation with each other.
I have also become interested in research into Physics pedagogy. The course materials that can be reached by links from my home page are an outgrowth of this research.
A third area of interest is the physics of sound and the acoustics of Renaissance and Baroque wind instruments.
