Dr. Bagge's research broadly focuses on increasing understanding of the etiology, course, and treatment of suicidal behaviors across the lifespan. Incorporating a multimodal approach, her research focuses on establishing a nomological net to characterize observed associations with suicidality in terms of directionality, temporality, and mechanisms of action. Her current research focuses on identifying and validating warning signs (e.g., acute substance use and interpersonal life events) for recent suicide attempts among psychiatric inpatients, as well as the interrelations among serotonergic genes, facets of impulsivity (using behavioral tasks), and suicide attempts. She also has a strong interest in statistics and psychometrics, personality traits and disorders, and substance use disorders. Dr. Bagge currently serves as Principal Investigator on an R21 grant funded by NIAAA and co-Principal Investigator on a large multi-site study funded by the Military Suicide Research Consortium.
