Sidarta Ribeiro

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.
