I am an applied microeconomist with main research interests in inequality, redistribution, uncertainty and intertemporal choice. My research combines economic theory and quantitative methods with data from large-population experiments, detailed administrative registers, and various markets and institutions. I taught/teach courses in decision theory, information economics, health economics, programming methods, empirical methods and data analytics.

I am on the 2020/2021 job market and available for interviews.
