As a clinical psychologist and researcher, I have dedicated a significant part of my professional career to training and to studying health from various disciplines, cultures and eras. I have delved into topics such as the benefits of psychotherapy for trauma, psychotherapy assisted with Amazonian plants or psychedelics, ethnobotany and traditional medical systems of indigenous nations of America (especially vegetalismo and other forms of Amazonian healing), the understanding of animism as scientific knowledge, the history of medicine, the scientific evidence on the therapeutic applications of psychedelics, drug policies and their impact on mental health, harm reduction as a health and human rights approach, among others.
