I am a Professor in the Department of Economics and Finance at the University of Guelph, specializing in applied microeconomics and human capital. My research examines how people acquire, use, and adapt their skills in a changing labour market. I have explored the effects of occupational mobility on the returns to training, and how aggregate and sectoral fluctuations influence firms’ decisions to invest in employee training. I have also studied the returns to post-secondary education, the determinants of the gender wage gap, and how immigrants transfer skills compared to natives. More recently, my work focuses on the dynamism of careers using matched employer–employee data. I am increasingly interested in applying machine learning and double-debiased algorithms to estimate conditional treatment effects, building on earlier work evaluating training and re-employment programs. Some of my current projects also focus on extracting and classifying skills from job postings using dynamic taxonomies, with the goal of understanding how new technologies reshape occupational skill demand and workforce transitions.
I am currently on sabbatical leave visiting CERGE-EI Prague in Fall 2025 and Carlos III Madrid in Winter and Spring 2026.
