I am an Assistant Professor in the Work & Organizations Group at the University of Minnesota's Carlson School of Management. My research is on work and employment issues, and especially on the economics of human resources. My recent research has involved working with companies to test the Peter Principle, evaluate the power of bonus pools, and examine how online ratings protect gig workers. My work has been published or forthcoming in the QJE, Management Science, JOLE, JHE, ILR Review, Industrial Relations, and Demography. Press coverage includes NY Times, WSJ, NPR, Washington Post, LA Times, NBC, CBS, PBS Newshour, HBR, The Economist, Financial Times, Times of London, Die Welt, The Globe and Mail, Bloomberg, Forbes, and Time Magazine.
