In addition to teaching at Queen’s, Stefan researches classroom assessment and uses his skills in the field to consult with varied organizations about assessment and conduct psychometric analyses of high stakes tests. He is currently on the board of the Canadian Educational Research Association.​

​

Stefan completed his undergrad in Honours Physics at UBC before landing a job at a particle physics lab. After two years of mesons and pions he realized that pure science was not for him and returned to UBC to complete his BEd in science and mathematics. The move was a fortuitous one as it turns out that education is his real passion. He completed his MEd in Educational Administration at UBC before leaving Canada to work in Singapore and Indonesia, and after 10 years away from academia decided to complete his PhD in educational assessment and measurement at Queen's University.
