At the time available computing power restricted the size to systems of about 100 to 120. Following the PhD I took a post-doctoral position in chemical physics at the Department of Chemistry, University of Toronto where I worked on simulations of combustion processes and simulation of chemical reactions in interstellar gases. Both of these fields required diagonalisation of large, sparse, stiff systems of equations. I accepted a Von Humboldt award to spend a year in Germany at the Technische Hochschule Darmstadt where I studied the theory of two photon effects on chemical reactions. After Germany came York University - and the rest is history as they say.

I also have office hours for advising majors in computer science concerning their degree programme. Apart from on going interests in numerical methods and scientific simulations I am also actively involved in developing multimedia course materials and, more importantly, evaluating their pedagogical effectiveness.
