He began teaching at Mount Royal in 2003. While he mainly teaches Physics courses, he has also taught Astronomy, Geophysics and General Education courses.

Raphael Slawinski was drawn to Physics because of the insights it offered into the universe around us. Thus, while earning a major in Physics, he also completed a minor in Astrophysics. He went on to earn a Masters degree in Astrophysics, developing statistical methods to analyze x-ray telescope data, to try to understand the nature of gamma-ray bursts. He did his doctoral dissertation in Geophysics, constructing computer models of how seismic waves propagate through fractured rock.

One of the areas he is interested in these days is atmospheric physics.
