Profile

Biography

I obtained my PhD from Comenius University (Slovakia) in 2008. Before moving to the United Kingdom in 2010, I worked as a statistician for research companies and held a teaching fellow position. I did my post-doctoral research at the University of Hertfordshire (2010-11) and King's College London (2011-2014). Before joining our department in 2015 I was a lecturer at Kingston University (2014-15). My lab is part of the Psychological Science Accelerator, an international network of psychological laboratories across the world aiming to conduct large-scale pre-registered studies. I serve as a member of the Study Selection Committee, responsible for the selection of the studies that are going to be run by the network. I contribute to the improvement of psychological science as an Ambassador of the Center for Open Science and as a member of The UK Network of Open Science Working Groups. I also serve on the editorial board of Studia Psychologica and Journal of Experimental Psychology: Applied.

Research and professional activities

Research interests

In my research, I am trying to understand how people estimate, judge, reason and make decisions in situations of uncertainty and risk, how people perform these processes on their own and in the presence of the others, and how people perform these processes in the lab and in the wild.

My basic research interests include perceptions of verbal probabilities, statistical reasoning, and intuitive and deliberative processing. My applied research interests include uncertainty and risk communication (e.g., climate change communication, communication between patients and doctors), and diagnostic and management decision-making of doctors.
