Our broad research interest lies in cognitive, affect, and decision sciences. The research group aims to understand the role of affect in risk, and reward representation in cognitive processes mainly decision-making. We examine cognitive, affect and decision processes under different conditions (ideal/ constraint) in healthy and clinical population. The group primarily uses behavioral experiments, combining these with imaging (fNIRS, structural MRI) to understand cognitive deficits in clinical conditions (neurological and psychiatric disorder). To control for environment influences or to study of cognitive deficits specific to a clinical disorder, the group collaborates with labs to use animal models (rodents). A multidisciplinary approach is needed to understand the hard problems such as the mind-body, or brain-behavior-cognition, therefore group members are selected from clinical psychology and biology, encouraged to collaborate with engineering and sciences.
