Background & Research
Sidarta Ribeiro is a Brazilian neuroscientist, science communicator and academic known for integrating systems neuroscience with experimental work on psychedelic compounds and altered states of consciousness. His research programme spans basic neurophysiology (including sleep, memory and cortical dynamics) and human psychopharmacology, with empirical contributions to studies of ayahuasca, DMT and LSD and co‑authorship on neuroimaging and electrophysiological work that probes how classic psychedelics alter large‑scale brain activity.
In recent years Ribeiro has also been active in translating basic findings into clinical and translational research in Brazil, including involvement in pilot and open‑label studies of psychedelic‑assisted interventions (for example MDMA‑assisted psychotherapy for severe PTSD) and critical commentary advocating for publicly funded, ethically conducted psychedelic research. He is recognised for combining laboratory neuroscience, neuroimaging, and clinical trial activity with public engagement to shape the emerging psychedelic research landscape in Latin America.
Key Impact
A leading Brazilian neuroscientist who has bridged basic neurophysiology and clinical psychedelic research, contributing influential studies on ayahuasca, DMT and LSD and helping to advance psychedelic-assisted therapies in Brazil.

View stakeholder →Chacruna
Non-ProfitChacruna is a nonprofit psychedelic education and advocacy platform based in the United States with global reach through online publishing, courses, conferences, and multilingual programming. Its work centers on psychedelic plant medicines, ethics, cultural justice, reciprocity, and Indigenous knowledge, with content and activities aimed at researchers, clinicians, educators, policy audiences, and the broader public. The organization says it bridges ceremony and science and makes academic knowledge more accessible through public-facing education. Chacruna plays an explicit role in psychedelic justice and policy-adjacent advocacy by foregrounding cultural context, equity, and protection of sacred plants and traditions. Current documented initiatives include the Indigenous Reciprocity Initiative of the Americas, which supports community-led Indigenous projects, the Psychedelic Culture conference, the bilingual Chacruna Latinoamérica platform, and courses on diversity, culture, social justice, ceremony, ethics, and reciprocity. These activities make it a potential partner for researchers, clinicians, funders, and policy groups seeking cultural consultation, educational programming, and community-centered collaboration.
