My work as a psychiatric epidemiologist focuses on environmental exposures and their link to the development of adverse health outcomes, including suboptimal pregnancy and birth outcomes, as well as psychopathology. I am particularly interested in reproductive events, including pregnancy and menopause. I have been instrumental in setting up two separate birth cohorts, and have conducted analyses in several existing birth cohorts to study the outcomes of early life exposure to, for example, maternal mental illness, medication, phthalates, and inflammation. I have also applied cognitive-neurophysiological and genetically sensitive longitudinal designs to study risk and protective factors for psychopathology, and the biological mechanisms underlying it, in large-scale national health and twin registries. My research is widely cited, including outside of the academic context, and has been recognised consistently for its excellence and innovation by internal and external funding bodies, including the National Institute of Child Health and Development (NICHD), the Simons Foundation Autism Research Initiative, the Brain & Behavior Research Foundation, and the Centers or Disease Control.
