Yunyu Xiao, Ph.D. is an Assistant Professor in Health Informatics Division, Department of Population Health Sciences at Weill Cornell Medicine, Cornell University. Her research leverages large, longitudinal, nationally representative, complex population-based, and electronic health records datasets to understand racial/ethnic, sex, gender, socioeconomic, and other disparities in suicide and mental health, taking a life-course and multilevel perspective to explore structural, social, and individual-level factors to reduce suicide and mental health. Then, this understanding informs social/behavioral and policy interventions to reduce disparities and improve health equity.
