Julie Aitken Schermer (formerly Harris) is a Professor in the Department of Management and Organizational Studies at The University of Western Ontario in London, Canada. She was an assistant professor at Brescia University College, London, Ontario for two years.  She was then hired as an assistant professor in the Administrative and Commercial Studies Program (later the Department of Management and Organizational Studies) in the Faculty of Social Sciences at The University of Western Ontario where she was tenured in 2006 and became full professor in 2014.  She has authored or co-authored 95 peer-reviewed articles, 7 book chapters, 3 editions of a Canadian Business Statistics textbook, the vocational interest measure, the Jackson Career Explorer, as well as over 100 conference presentations.  Her publications have appeared in journals such as Journal of Career Assessment, Journal of Intelligence, Personality and Individual Differences, and Twin Research and Human Genetics.  She is senior associate editor for Personality and Individual Differences and is on the editorial board for Journal of Intelligence.

Julie Aitken Schermer’s research interests include personality, intelligence, vocational interests, and behaviour genetics.  In her past research, she has shown that twins are more accurate in judging their co-twin’s personality on traits that are more heritable, that testosterone is heritable in both men and women, and that personality and intelligence have meaningful correlations.  Presently she is working on refining her vocational interest measure, the Jackson Career Explorer, a continuous and behaviourally based assessment tool.
