My research interest lies in developing and applying innovative methods in statistical genetics to understand the etiology of psychiatric, psychological, and behavioral traits. I focus on the interplay between genetic and environmental factors, including gene-by-environment interactions, with an emphasis on multivariate models and structural equation modeling for complex trait analyses. I leverage large-scale genome-wide association studies (GWAS) to elucidate the shared and distinct genetic architectures underlying psychiatric disorders. Additionally, I work on open-source analytics platforms (notably GenomicSEM) that facilitate transparent, reproducible science. My longitudinal approaches clarify stability and change in psychopathology across the lifespan and ultimately advance personalized risk prediction.
