About Our Lab
Research in the lab examines the neural and computational principles of reward-guided behavior, with a focus on odor-guided behavior. We study brain systems involved in reward processing, learning, generalization, and decision-making such as the striatum and the orbitofrontal cortex. For this, we use a combination of human olfactory psychophysics, computational modeling, fMRI and advanced multivariate analyses techniques borrowed from machine learning. This research may pave the way for understanding decision-making deficits in neurological diseases and addiction, and should ultimately lead to novel diagnostic markers and treatment strategies for these disorders.
