Ph.D (Theoretical Nuclear Physics) University of Alberta, 1989
B.Sc. (Honours Physics) University of Alberta, 1982
I have been teaching physics and mathematics at Augustana since 1990.
How the physical world works fascinates me and I try to convey the beauty of physics and mathematics to students.
I am a theoretical physicist, but through teaching have come to really appreciate and learn the tools of the trade of the experimental side of physics.
I very much enjoy being active outdoors, especially running, biking and cross country skiing. I coach the Augustana running team ( augustanarunning.ca ) on the side.
Teaching
Teaching is at the heart of what we do at Augustana.
I try to convey my enthusiasm for physics and encourage students to think broadly about what physics is, how it works, and why it is important to understand for living in our highly technological world.
I have taught every physics course offered at Augustana, and many mathematics courses.
Scholarly activity
My specific research is in theoretical nuclear physics. Basically I try to understand how the atomic nucleus works. In particular, I model photonucleon knockout reactions using the relativistic quantum mechanical Dirac equation.
It is important and fulfilling to be a generalist at a small undergraduate institution. I have developed strong interests in astrophysics and experimental physics while working at Augustana.
I enjoy learning more about and presenting interesting aspects of physics, such as astronomy, nuclear energy, and the nature of time, to broader audiences.

Limits; differentiation and integration of algebraic, trigonometric, exponential, and logarithmic functions; applications. Prerequisite: Mathematics 30-1. Notes: Credit may be obtained for only one of AUMAT 110 and 116. Students with credit in Mathematics 31 who score 80% or more on the Calculus Placement Test should take AUMAT 116 instead of AUMAT 110. Students with unsatisfactory performance through the first four weeks of the course are advised to withdraw and register in the next offering of AUMAT 101.
