Nikhil Varghese

Nikhil Varghese is a clinical researcher specialising in experimental psychopharmacology with a focus on human laboratory studies of psychedelic compounds. His work centres on rigorous, placebo‑controlled, randomized and crossover trials that characterise acute subjective, physiological and safety profiles of serotonergic psychedelics. Varghese has contributed to multiple high‑quality trials investigating dose‑response relationships for LSD, the acute effects of intravenous DMT, the pharmacology of MDMA enantiomers, co‑administration effects of MDMA and LSD, and the interaction between psilocybin and SSRI pretreatment.

Through these studies, Varghese has helped clarify acute pharmacodynamic effects, tolerability and experimental paradigms used in healthy volunteer models, informing both mechanistic understanding (including receptor involvement and phenomenology) and translational considerations for therapeutic development in anxiety, trauma‑related and depressive disorders. His methodological emphasis on double‑blind, placebo‑controlled designs and cross‑over approaches has strengthened the evidence base for dose selection, safety monitoring and the interpretation of subjective and objective outcome measures in modern psychedelic research.
