Her academic background includes an undergraduate degree and a master’s degree in Psychology from Basel University, as well as a PhD in Human Sciences from Heidelberg University. Dr. Meier’s research focuses on leveraging modern technology to improve mental health care in youth, including the development of smartphone apps that passively gather behavioural data to identify at-risk individuals early and support timely intervention. She is also interested in genetic risk factors and long-term outcomes of anxiety disorders, obsessive-compulsive disorder, and related conditions.
Dr. Meier has received multiple awards, including PhD awards from the Faculty of Medicine at Heidelberg University, the Romius Foundation at Novartis AG, and the German Society for Psychiatry, Psychotherapy and Psychosomatics, as well as the Young Researcher Award from the World Association of Stress-related and Anxiety Disorders. Key publications include a 2019 genome-wide association study of anxiety and stress-related disorders in the iPSYCH cohort published in JAMA Psychiatry, a 2018 study on attention-deficit hyperactivity disorder and anxiety disorders as precursors of bipolar disorder in the British Journal of Psychiatry, and a 2016 study on mortality among persons with obsessive-compulsive disorder in Denmark published in JAMA Psychiatry. She teaches courses in psychiatric epidemiology, behavioural psychiatry, statistics, and psychiatric genetics, and maintains memberships in the International Society of Psychiatric Genetics and the German Society for Biological Psychiatry.
