More information


I am Assistant Professor at Rotterdam School of Management. Before joining Erasmus University, I held a postdoctoral position at Boston University and I was a research affiliate at MIT. My research develops and evaluates marketing interventions designed to stimulate societally desirable consumer behaviors. I am using mixed methods from laboratory, online experiments to analyses of secondary data with econometric and meta-analytical techniques.
