Biography
Year of entry: 2015
Research Profile
My research interests lie in the study of the effectiveness of interventions against disadvantageous decision-making, namely in health and, for the moment, dietary decision-making. In my dissertation, I explore how quantitative (ex. machine learning), behavioral (ex. economic experiments), and neuroscientific (ex. fMRI and rTMS) methods provide insight into self-control interventions ranging from the medical to the managerial. I source my data from experimental settings and randomized control trial retail data.
