Gregor Hasler

Gregor Hasler is a Professor of Psychiatry and Psychotherapy at the University of Fribourg, specializing in depression, eating disorders, and the complex relationship between nutrition and mental health. During a three-yer research fellowship at the National Institute of Mental Health in Bethesda (USA), he deepened his expertise in the fields of stress, reward systems, and their connection to eating behaviours and well-being. His current research focuses on the interplay of social, psychological, biological and nutritional factors in the prevention and treatment of mental disorders, with a particular emphasis on how nutrition impacts the gut-brain axis and emotional resilience.

A recognized thought leader, Gregor Hasler delivers lectures both in Switzerland and internationally on topics such as eating disorders, depression, stress, resilience, and the role of nutrition in mental health. He is particularly interested in how dietary habits and the microbiome influence psychological states and how certain foods can promote or hinder emotional well-being. His cohort study on the gut-brain axis explores the impact of eating behaviors and gastrointestinal health on the microbiome and mental health, providing critical insights into how nutrition can be a powerful tool for psychological resilience and recovery.

His scientific contributions have been recognized with numerous national and international awards, including the prestigious Robert Bing Prize from the Swiss Academy of Medical Sciences. Through his research, writing, and public engagement, he seeks to bridge the gap between cutting-edge science and practical guidance, helping individuals understand how what they eat shapes not only their physical health but also their mental and emotional well-being.
