Research interests

My main research interest is Behavioral Operations Management – a research stream that explores how individuals make decisions in operational contexts. My studies address human decision making in inventory management, supply chain contacting, healthcare settings, project management, and innovation management as well as decision support systems. A common denominator of most of my studies is the use of laboratory experiments as the main method. They provide an important opportunity to obtain new insights and to link theory and practice. Since the human element is a common influencing factor in many operations processes, analytical models are often based on assumptions about decision maker’s behavior and their goals in order to make the mathematics tractable. Experiments can either validate or challenge the assumptions and implications of analytical models and complement analytical approaches by bridging the gap between models and real business problems. I appreciate the various modes of research (experimental, empirical, and analytical) and I am especially interested in conducting research projects solving industry problems.
