Lottie Bullens graduated (cum laude) from the UvA research master in 2007. After working as a research assistant in the Brain and Development lab at Leiden University for some time, she started her PhD project in June 2008 at the University of Amsterdam and partly at Columba University in New York. In 2013, she defended her dissertation (cum laude) "Having second thoughts: consequences of decision reversibility". Thereafter, she worked as a market researcher at Ipsos in Amsterdam for over a year. Currently, she is Assistant Professor at Leiden University. Her research focuses on the antecedents and consequences of different forms of choice-related stress and uncertainty.


In her research, Lottie Bullens especially focuses on (consumer) decision-making. She is very interested in the way people make decisions, which emotions and motivations play a role during the decision making process, which factors contribute to choice-related stress and insecurity, and the different ways people deal with such sress and insecurity.
