I am an experimental economist focusing on decision-making under uncertainty, social preferences, and healthcare. My research has been published in leading economic and biology journals. Throughout my academic career, I have managed experimental laboratories and taught behavioral economics and neuroeconomics. As part of my outreach efforts, I founded the Prague Conference on Behavioral Sciences and the Czech Summer School on Behavioral Economics, which have attracted hundreds of students and scholars since 2017. I have also collaborated with institutions in the USA, the Netherlands, and India.
