Rick Doblin, Ph.D., is the Founder and President of the Multidisciplinary Association for Psychedelic Studies (MAPS), an organization he founded in 1986 to develop medical, legal, and cultural frameworks for the responsible use of psychedelics and marijuana. He received his Ph.D. in Public Policy from Harvard University’s Kennedy School of Government, where his doctoral dissertation examined the regulation of the medical uses of psychedelics and marijuana. 

Rick’s academic work began even earlier with his undergraduate thesis at New College of Florida, a 25-year follow-up to the classic Good Friday Experiment, which explored the capacity of psychedelic substances to catalyze religious and mystical experiences. He later conducted a 34-year follow-up study of Timothy Leary’s Concord Prison Experiment, further contributing to the long-term understanding of psychedelics’ psychological and social impacts.

In addition to his research and policy work, Rick studied with Dr. Stanislav Grof and was among the first individuals to be certified as a Holotropic Breathwork practitioner. His professional goal has been to help establish legal contexts for the beneficial use of psychedelics and marijuana—primarily as prescription medicines, but also for personal growth among otherwise healthy individuals—and ultimately to see the emergence of legally licensed psychedelic therapists. 

Dr. Rosalind Watts is a clinical psychologist, researcher, and integration specialist whose work has significantly shaped the contemporary psychedelic field. She served as Clinical Lead for Imperial College London’s psilocybin trials, contributing to some of the most influential modern research on psychedelic-assisted therapy. Her work has been widely recognized, including being named among the 50 Most Influential People in Psychedelics and one of the Top Women Shaping the Future of Psychedelics.

Beyond research, Dr. Watts has focused deeply on integration, harm reduction, and inclusion. She has consistently emphasized that safe and effective psychedelic use depends on sustained integration support rather than the experience alone. In response, she founded ACER (Accept, Connect, Embody, Restore) Integration, a global 13-month integration program supporting long-term personal, relational, and ecological reconnection.

A mother and nature lover, Rosalind’s work is informed by ecological thinking and a commitment to fostering connectedness between self, others, and the natural world.

Sara Reed is a mental health futurist and has spent her early career reimagining effective mental health care in the medical system. Sara's clinical interests focus on ethical care in psychedelic sessions, examining ways culture informs how we diagnose and treat mental illnesses. 

Before joining the Centre for Psychedelic Research, Sara participated as a study therapist with the MDMA therapy for PTSD clinical trials sponsored by the Multidisciplinary Association for Psychedelic Studies (MAPS). While working with MAPS, she advocated for health equity in psychedelic therapy and co-led the first-ever MAPS MDMA-assisted psychotherapy training for clinicians of color. After this study ended, she received training in psilocybin therapy at Yale University for the "Psilocybin-Induced Neuroplasticity in the Treatment of Major Depressive Disorder" trial and co-wrote a paper using Acceptance and Commitment Therapy as a therapeutic modality in this treatment.

Sara is now the Senior Psychedelic Research Therapist at Imperial, where she provides line management and therapeutic leadership across multiple psychedelic research studies. She also serves as the Brain Sciences Department EDI Co-Lead, focusing on equity, diversity, and inclusion in research and practice. In addition, Sara lectures on the integration of culturally responsive approaches within psychedelic-assisted therapy and advises organizations on building ethical, anti-oppressive, and inclusive care models.

Dr. Will Siu grew up in California and completed his studies at UC Irvine, UCLA, and the University of Oxford, where he earned his doctoral degree. His career path led him to research at the National Institutes of Health in Washington, DC, followed by psychiatry training at Massachusetts General Hospital and McLean Hospital in Boston. He then joined the faculty at Harvard Medical School and remained at McLean Hospital for two years before moving into private practice.

Over time, Dr. Siu expanded beyond traditional psychiatry to incorporate contemplative practices, depth psychology, and mystical and spiritual traditions. This integration informs his approach to understanding suffering, healing, and consciousness, blending scientific rigor with the deeper dimensions of human experience.

While he does not provide psychedelic sessions, Dr. Siu draws on his training in psychedelic-assisted therapy when appropriate, viewing these approaches as part of a broader framework of care. At the heart of his work is the therapeutic relationship — an attuned space where people can safely explore their inner world and achieve more freedom: to live with greater clarity, creativity, connection, and self-trust.

As a coach, Daniel helps individuals integrate non-ordinary states into sustainable, values-aligned change, supporting them to live with intention, compassion, and coherence. His approach is fiercely practical while honoring the mystery and sacredness of psychedelic experience. With time-tested and scientifically informed tools, Daniel meets clients at the threshold between insight and action, helping them build lives that reflect their deepest truths.

Through Tam Integration, Daniel has cultivated a global platform for education and connection, offering accessible, inclusive, and ethically rooted integration spaces for emerging leaders and seekers alike. 

Dr. Glauber Loures de Assis is a researcher of sacred plants and their traditions and a psychedelic dad. He has a Ph.D in sociology from the Federal University of Minas Gerais (UFMG) in Brazil.

He has 15 years of experience with ayahuasca and other sacred plants and has led more than 500 ceremonies in Brazil, Europe, and the United States. He has built this practice in dialogue with his local Brazilian ayahuasca community and with the blessings of Indigenous elders and activists in Brazil. He is also the leader of Jornadas de Kura, a plant medicine center in Brazil that promotes a bridge between the ceremonial use of sacred plants, public education on plant medicine, and psychedelic science. He is an Indigenous rights activist and the Director of the Psychedelic Parenthood Community. He is a father to 3 children and lives with his wife Jacqueline Rodrigues in Santa Luzia, Minas Gerais, Brazil.

Hattie Wells is a psychedelic practitioner, educator, and drug policy reform advocate with more than twenty years of experience in the field. In the early 2000s, she was among the first practitioners in the UK to facilitate ibogaine treatments for addiction, and has since dedicated her career to researching, practicing, and communicating about the therapeutic use of psychedelics.

Her work spans harm reduction, clinical research, ethnobotany, and advocacy. She has collaborated with organizations including the Beckley Foundation, Transform Drug Policy Foundation, Psyaware, and ICEERS, working to reduce harms associated with drug use and challenge punitive drug policies.

Hattie has conducted ethnobotanical research with the San Bushmen in Namibia and currently works as a therapy guide in psychedelic clinical trials involving ibogaine and 5-MeO-DMT. She is a co-director of Breaking Convention and a board member of the Global Iboga Therapeutic Alliance (GITA). She lives in Bristol with her two daughters.

Philip Carr-Gomm is a psychologist, psychotherapist, author, and former Chosen Chief of the Order of Bards, Ovates and Druids (OBOD), a role he held for over three decades. He studied psychology at University College London and trained in psychotherapy at the Institute of Psychosynthesis, alongside training in play therapy, sophrology, and contemplative practices.

His spiritual path began in adolescence under the mentorship of Ross Nichols, founder of OBOD, and later expanded through study of meditation, perennial wisdom traditions, and Druidry. Philip’s work emphasizes the integration of psychology and spirituality, drawing from what he describes as the Universal Mystic tradition — the shared wisdom underlying diverse spiritual paths.

He has authored numerous books, founded educational initiatives including The Art of Living Well, and is currently involved with ACER Integration and the Sophrology Institute. Philip lives in Sussex, England, where his work continues to explore the meeting place of inner development, ritual, and psychological insight.
