Systems and Computational Neuroscience

Cognitive and Behavioural Neuroscience

Interests

My research aims to provide a mechanistic understanding on how the brain constructs the values used to guide choice. I approach this complex problem by combining a number of different theoretical frameworks from economics and computational neuroscience with cutting-edge tools from experimental neuroscience. This interdisciplinary approach aims to shed light on why human decisions are so often imperfect, helping policymakers and economists in designing new interventions and institutions to improve them.
