Wietse is a Professor in Global Mental Health at the Section of Global Health, Department of Public Health at the University of Copenhagen; Professor (Adjunct) at the Department of Mental Health, Johns Hopkins Bloomberg School of Public Health; and Senior Technical Advisor with HealthRight International. He holds an MA in Clinical and Health Psychology (Leiden University), a Ph.D. in Public Mental Health (Vrije Universiteit Amsterdam), and was a global health postdoctoral fellow at Yale University. Dr Tol’s research and practice focus on mental health and psychosocial support interventions for adversity-affected populations in low- and middle-income countries. In particular, his work centers on (integrated) interventions that address mental health and the social determinants of mental health, and he is very interested in understanding how research can lead to improved practice (and vice versa). He regularly consults with UN agencies and (international) non-governmental organizations in the areas of mental health and psychosocial support needs assessment, intervention selection and development, monitoring, and evaluation.
