Louis Lippens

Louis Lippens

I am an FWO postdoctoral fellow and lecturer at Ghent University, and a labour economist studying how labour markets treat people. I hold a joint PhD in Economics and Sociology from Ghent University and Vrije Universiteit Brussel. Most of my work concerns hiring discrimination, which I examine through correspondence and audit field experiments and by synthesising the wider evidence base with meta-analysis. The same empirical lens carries into my other interests, which include unemployment and inactivity, alternative work arrangements, and the growing role of generative AI in the labour market. I am affiliated with UGent@Work and IZA@LISER, and I serve on the Ethics Board of the Flemish Public Employment Services (VDAB).
