Key Impact
Notable for experimental human psychopharmacology of novel hallucinogens and influential work on psilocybin's effects on personality and the measurement of mystical-type experiences.
Background & Research
Katherine A. MacLean, PhD, is a research psychologist whose work centres on human psychopharmacology, clinical applications of classic and atypical psychedelics, and the psychometric and ethical questions that arise in psychedelic-assisted therapies. Her research portfolio spans controlled laboratory dose–response studies of compounds such as salvinorin A (a kappa-opioid agonist) through to clinical and secondary-analytical work on psilocybin-assisted therapy and its effects on personality and subjective mystical-type experiences. MacLean combines quantitative experimental designs with psychometric evaluation and qualitative inquiry to probe both acute drug effects and longer-term psychological change.
