David studied mathematics at the TU Kaiserslautern until 2008. In his master thesis he analyzed the earth’s gravity signal derived from satellite measurements. He was interested in detecting local gravity field anomalies in areas with strong volcanic activity (e.g. Iceland, Hawaii) utilizing so called Wavelets. As a lateral entrant in the field of neuroscience, he focuses on obesity-related alterations in reward-based learning and cost-benefit decision-making processes. Specifically, in his latest PhD project he’s aiming at revealing if obese subjects show alterations in the trade-off between physical effort as a form of costs and different types of rewards (e.g. high-caloric snacks, money, etc.) during cost-benefit decisions. Beside basic behavioral measurements, he uses functional magnetic resonance imaging (fMRI) techniques to detect the neural correlates that underlie the behavioral observations.
