Research interests

Epidemiological studies and clinical trials on suicidal behavior and -thoughts. My primary research focus is trends in risk and risk factors for suicide as well as studying the effect of interventions aimed at preventing suicidality. Most of my work has been dedicated to suicidality in psychiatric patients; however, my research interest within suicidality is not limited to this population.
