Candidate Gene Studies

Integrating methods from molecular biology and cognitive science, our association studies investigate genetic influences on psychological and biological aspects of emotion and cognition. We have focused on functional polymorphisms in genes related to neural signaling or neural development, such as the serotonin transporter (5-HTT), the brain-derived neurotrophic factor (BDNF), the catechol-O-methyltransferase (COMT) and the corticotropin-releasing factortype one receptor (CRFR1) genes, but more polymorphisms are added every year. Our studies aim to identify genetic influences on emotional development during adolescence and early adulthood, genetic moderators of the relations between emotion and cognition, and cognitive and neural endophenotypes of emotional vulnerability.​​​​​​​
