Ian Krajbich
Research
I am a neuroeconomist with a background in both the social sciences and neuroscience. My research combines tools from psychology, neuroscience and economics (e.g. fMRI, eye-tracking, lesions, machine learning, game theory) to investigate the mechanisms behind decision-making and to tackle basic questions in economics. My recent research has focused on using neural signals of value as inputs to mechanism design, investigating the effects of visual attention on economic decision-making, and modelling choice behavior using drift-diffusion models. My current research in Zurich is partially building on my previous work, and partially investigating the neural mechanisms of social preferences and social influences on decision-making.
