In a recent interview with Genomic Press, Swiss psychiatrist Gregor Hasler demonstrated how psychedelics can rapidly reorganize brain function, with the potential to deliver stronger, longer-lasting benefits than conventional approaches. Integrating both traditional and innovative approaches, Hasler serves as Chair of Psychiatry at the University of Fribourg and Director of its Molecular Psychiatry Laboratory. Hasler’s research builds on Switzerland’s long tradition of mental health innovation, a history that ranges from the creation of early antidepressants and benzodiazepines to Albert Hofmann’s discovery of LSD. This broad foundation enhances Hasler’s expertise in both psychology and molecular psychiatry, helping him connect brain chemistry with clinical outcomes. He merges neuroimaging and clinical research to analyze how psychedelics affect consciousness and brain activity.
