Dr. Des. Larissa J. Maier PhD

Larissa is a postdoctoral research fellow working at the Swiss Research Institute for Public Health and Addiction (ISGF), an affiliated institute of the University of Zurich. In March 2015, she completed her doctoral degree at the University of Zurich in Psychology, where she specialised in Clinical and Health Psychology. Larissa’s research interests focus on the epidemiological and sociological consideration of pharmacological neuroenhancement, psychological well-being, and psychoactive substance use as self-medication to cope with stress or psychiatric symptoms. In this context, neuroscientific research considering altered cognitive and affective function is of great significance for her. Furthermore, she has conducted research on early detection of problematic substance use patterns in nightlife settings to provide instruments for early intervention. As a clinical psychologist, she also follows the debate on the therapeutic potential of psychedelic drugs for the treatment of PTSD, anxiety, depression, and addiction.
