At INLIBRIUM, Dr. Lebedev leads the psilocybin sessions during the residencies. He brings to them a psychiatrist’s eye for risk, a neuroscientist’s understanding of what these compounds do in the brain, and years of hands-on work with screening, preparation, and integration.
Dr. Lebedev has spent more than 20 years in clinical practice, research, and leadership at European universities. His research has followed one thread: how the brain forms and revises beliefs, from the role of dopamine and serotonin in learning to the way large-scale shifts in a society’s mood leave traces in human brains.
His view of psychedelics is neither romantic nor alarmist. He treats them as medicine that lives where molecule and meaning meet: the substance matters, but so do the setting, the relationship with the people in the room, and what happens in the weeks that follow. That is why he gives sleep, context, and follow-through the same weight as the session itself.
Dr. Lebedev’s work is shaped by a simple standard: a model, metric, or compelling explanation is valuable only when its limits are visible. He brings that discipline to individualized care—asking what the evidence supports, what it cannot establish, and what should still be decided through careful human judgment.
