Paths Into Psychedelics: Graduate Student Panel
Natasha Greenstein
Master’s Student at the Center for Brain and Cognition, Universitat Pompeu Fabra, Barcelona, Spain & The Institute of Noetic Sciences (IONS), Novato, California, USA
Natasha studies the intersection of quantum physics, neural systems, and psychedelic science. After completing her bachelor's in physics at Princeton University, she is now in the last month of her master's in Brain and Cognition at Universitat Pompeu Fabra in Barcelona, following a collaboration on her senior thesis. Her current research spans a broad range of topics, with her master's thesis Congruent signatures of fractal criticality are reflected across quantum and cortical scales demonstrating how quantum information is propagated all the way to the whole brain level, both in resting and DMT states. Outside of research, Natasha enjoys spending time in nature, yoga, lifting, running, and jamming to music with friends.
Rafaelle Lancelotta, MS, LPCC, PhD(c)
PhD Candidate, The Ohio State University, Center for Psychedelic Drug Research and Education
Rafaelle Lancelotta, LPCC, is a PhD candidate at The Ohio State University College of Social Work, defending her dissertation in July 2026. Working with the Center for Psychedelic Drug Research and Education, her research has focused on extrapharmacological factors in psychedelic-assisted therapy; particularly how relational and social contexts shape therapeutic outcomes in naturalistic and clinical settings. She has authored 25+ peer-reviewed publications since 2016 and presented internationally on psychedelic therapy, healthcare equity, 5-MeO-DMT, and the experiences of gender and sexual minority communities in psychedelic contexts. Rafaelle brings extensive clinical experience as a somatic-focused, trauma-informed therapist in private practice, including work on two psilocybin-assisted therapy trials with veterans with PTSD and patients with lung cancer.
Iva Totomanova, PhD(c)
PhD Candidate, Psychopharmacology Section at Maastricht University
Iva Totomanova is a PhD Candidate at the Department of Neuropsychology and Psychopharmacology at Maastricht University. Her primary research interest lies in exploring the connection between the mind and the brain, and how pharmacological substances can influence cognition, emotion, and behavior. In her work, Iva is investigating the potential of psychedelics to bring about these powerful transformations, and their possible clinical applications. She is currently focused on examining the capacity of low doses of psilocybin to alleviate symptoms of adult ADHD, and the mechanisms underlying this effect. Next to this, Iva is involved in a range of other projects exploring psychedelic microdosing and the factors that contribute to inter-individual differences in both microdosing practices and their subjective effects.
