Jon Dean

Jon Dean, PhD

Center for Psychedelic Research, UC San Diego

Jon Dean, PhD, is a Co-Founder of the University of California, San Diego’s (UCSD) Center for Psychedelic Research (CPR), and Director of its DMT Division. Jon obtained his undergraduate degree in Chemistry in his hometown of Youngstown, Ohio, and his doctorate in Molecular and Integrative Physiology from the University of Michigan. During his doctoral studies, Jon discovered that N,N-dimethyltryptamine (DMT) occurs in the living mammalian (rodent) brain at concentrations comparable to the neurotransmitter serotonin. His preclinical doctoral thesis also demonstrated that the prefrontal cortex plays a pivotal role in regulating consciousness via the neurotransmitter acetylcholine, and that level of consciousness can be dissociated from electroencephalographic measures of cortical functional connectivity and cortical dynamics.

Jon and his CPR colleagues recently completed the first ever functional magnetic resonance imaging clinical trial on psilocybin for chronic pain, in individuals experiencing phantom limb pain, at UCSD. Jon’s postdoctoral studies at UCSD have also helped elucidate the brain and psychological mechanisms supporting mindfulness meditation for relief of cancer and chronic low back pain, as well as the role of endogenous opioids in mindfulness-induced analgesia. Jon and the CPR are currently spearheading neuroimaging studies on extended state DMT, with an emphasis on better appreciating its clinical applications, the nature of reality, and the role of endogenous DMT in the human body.

Jon has been recognized as a Sanford Fellow by the UCSD T. Denny Sanford Institute for Empathy and Compassion for his work on psychedelics for cultivation of compassion. His studies investigating the brain mechanisms of mindfulness meditation for pain and stress relief are funded by the National Center for Complementary and Integrative Health. Jon’s DMT research has been featured in the “DMT Quest” documentary as well as discussed on multiple podcasts, e.g., The Aubrey Marcus Podcast.

Andres Gomes-Emilsson

Andres Gomes-Emilsson

Qualia Research Institute (QRI)

Andrés is the President and Director of Research at the Qualia Research Institute (QRI), where he leads a multidisciplinary team exploring the nature of consciousness. His work spans a wide range of fields, including philosophy of mind, psychology, neuroscience, and signal processing. Through his blog, Qualia Computing, since 2014 Andrés has introduced novel paradigms to explain the phenomenology of altered states of consciousness, personal identity, and the structural basis of valence.

One of his notable contributions is the development of algorithmic reductions of psychedelic states of consciousness, which has led to innovative interpretative frameworks for understanding the phenomenology of DMT experiences in terms of non-Euclidean geometry, as described in his work “The Hyperbolic Geometry of DMT Experiences.” Andrés has also outlined potential paths for creating high-quality think tanks and research paradigms aimed at reverse-engineering the computational properties of consciousness.

Currently, Andrés is actively developing psychophysics tools to rigorously measure the phenomenology of exotic states of consciousness, such as those induced by psychedelics and Jhana meditation. Additionally, he is working on alleviating extreme suffering using pragmatic technologies. He also studies extremely high valence states of consciousness and is developing neurotechnology to induce these states safely and sustainably.

At QRI, Andrés is dedicated to developing a comprehensive philosophical and scientific framework to catalog, describe, and ultimately utilize uncharted configurations of the mind for computational purposes in an ethical manner.

His educational background includes a Symbolic Systems undergraduate degree and a Psychology masters, both from Stanford University. Professionally, he has worked as a data scientist and statistician in various fields, including Natural Language Processing, Affective Psychology, and Graph Theory. In his free time, Andrés enjoys creating novel perfumes that reveal unusual and surprising features of the state-space of olfaction.

Wim Hof

Wim Hof

Wim Hof Method

Wim Hof also known as The Iceman is the founder of the Wim Hof Method, a protocol utilizing respiration techniques, meditation, and cold immersion to develop mental and physical resilience. Wim has held multiple world records for feats of endurance such as swimming under ice, prolonged full-body contact in cold immersion, & running a half marathon barefoot in the snow. In 2011, Wim ran a full 26 mile marathon in the Namibian desert without drinking any water or fluids. In 2014, the Proceedings of the National Academy of Sciences published a study on the Wim Hof Method showing that a combination of breathing techniques, cold immersion, and focused attention empowered subjects to consciously influence their autonomic nervous systems and immune systems. The volunteers were injected with e. Coli and displayed a significant level of resilience to the endotoxin compared to the group that had not undergone 10 days of Wim Hof Method training. Since then multiple studies have taken place outlining various unique physiological mechanisms associated with the method.

Wim believes that the full human potential is only now emerging at the forefront of societal display and that much more lies ahead for the future of humanity. He has significant interest in future research ranging from mapping altered states of consciousness to utilizing his method to combat neurodegenerative conditions, autoimmune disease, and much more. There is significant public discourse regarding the potential upregulation of endogenous DMT from the Wim Hof Method but future research needs to take place to validate these speculations. Wim has reached millions of people with appearances on video programming such as the BBC, Gwyneth Paltrow’s Goop Lab, Vice, Yes Theory, and DMT Quest.

Joachim Keppler, PhD


Joachim Keppler studied physics at the Friedrich-Alexander University of Erlangen and received his PhD for research in theoretical particle physics and quantum field theory. He then worked in industrial research and development and held leading positions in the fields of data science and artificial intelligence. In addition to his interest in the deep understanding of the physical world, Joachim has always been engaged in the question of how consciousness can be integrated into the worldview of physics. In 2012, he launched the research institute DIWISS which is funded by private foundations and concentrates on the scientific exploration of consciousness pursuing an interdisciplinary approach at the intersection of theoretical physics, cognitive neuroscience, and philosophy of mind. Joachim’s research focus lies on unveiling the universal mechanism underlying conscious processes and establishing a sound basis for a theory of consciousness. At the heart of the scientific approach lies a paradigm shift from a neural substrate of consciousness to a ubiquitous substrate of consciousness that can be accessed via a coupling mechanism. The current research projects deal with collective phenomena and self-organized criticality in the brain and aim at building a model of cortical dynamics that provides valuable clues to the details of the coupling principle.

Chris Letheby

Chris Letherby

University of Western Australia

Dr Chris Letheby is a Senior Lecturer in Philosophy at The University of Western Australia (UWA). His areas of specialization are philosophy of mind, philosophy of cognitive science, and philosophy of neuroscience. His research interests include the causal mechanisms and epistemic status of transformative spiritual practices, the possibility of a “naturalistic spirituality”, and the nature of self-awareness. At UWA he teaches topics including intro to philosophy, formal logic, epistemology, philosophy of mind, philosophy of science, philosophy of artificial intelligence, and philosophy of psychology and psychiatry.

Letheby’s research to date has focused mainly on the use of classic psychedelic drugs in neuroscience and psychiatry. In several articles and a book, he has argued that a traditional conception of psychedelics as agents of insight and spirituality can be reconciled with naturalism, the philosophical position that the natural world is all there is. He takes a neurophilosophical approach, grounding his philosophical analyses in scientific findings, and he has engaged in several interdisciplinary collaborations with neuroscientists and psychologists.

Letheby’s monograph Philosophy of Psychedelics was published in 2021 by Oxford University Press, in the series International Perspectives in Philosophy and Psychiatry. An open-access symposium featuring multiple commentaries on the book was published in 2022 by the journal Philosophy and the Mind Sciences. The book has received two awards, both from The University of Adelaide (where Letheby worked as a postdoc while writing it): the Faculty of Arts Prize for Outstanding Research by an Early Career Researcher and the School of Humanities Early Career Prize for best publication in 2021. A Spanish translation was published in 2022 by Editorial Bauplan. Along with Professor Philip Gerrans (Adelaide), Letheby has edited a collection of essays, Philosophical Perspectives on Psychedelic Psychiatry, which is due out from OUP in August 2024.

Charlotte Martial, PhD


Charlotte Martial is a neuroscientist at the Coma Science Group (GIGA-Consciousness, University of Liège, Belgium), leading the projects on the phenomenon of near-death experience. More generally, Charlotte studies conditions in which people are outwardly unresponsive such as during general anesthesia or cardiac arrest, but ‘disconnected’ or ‘connected’ to the world, as testified by the detailed subjective reports upon awakening. In recent years, she has work more extensively on the comparison between (a)typical psychedelic experiences and near-death experiences, suggesting that the former may model the latter in laboratory settings. To broaden her exploration of human consciousness, she has delved into a comprehensive spectrum of physiological (e.g., hypnosis, cognitive trance), pathological (e.g., disorder of consciousness), and pharmacological (e.g., anesthesia) conditions, demonstrating that unresponsiveness cannot be considered as a surrogate of unconsciousness employing state-of-the-art multimodal functional neuroimaging techniques. Her research is embedded within a unique intellectual framework beyond the classical disciplinary perspectives in science and medicine.

She has published more than 75 papers in international peer-reviewed journals such as Trends in Cognitive Sciences, Critical Care, Sciences Advances and NeuroImage, and several book chapters. Her contributions have been recognized with awards such as the prestigious International Brain Injury Association (IBIA) Young Investigator Award. She has been invited in numerous international conferences as a (keynote) speaker and moderator, and has served on scientific organizing committees of several conferences such as at the New York Academy of Sciences. She has been Guest Associate Editor for special issues for peer-reviewed journals such as Journal of Cognitive Neuroscience and Current Opinion in Behavioral Sciences. Currently, she supervises several PhD students, with a long-term aim of advancing the understanding of near-death experience, while promoting education and public awareness about this captivating clinical and research field.

Pascal Michael

Pascal Michael, PhD

University of Greenwich

Dr. Pascal Michael received a BSc Hons (University of Aberdeen) in Neuroscience, where he helped show the neurotrophic capacity of the Omega-3 fatty-acid EPA, and an MSc (University College London) in Clinical Mental Health Sciences, exploring the post-acute effects on wellbeing of DMT. He completed his PhD in Psychology at the University of Greenwich in 2023 on a comparative analysis of the neurophenomenology of DMT (and analogous) experiences and the near-death experience (NDE), involving the first conceived field study of DMT use. He has been a lecturer there since, teaching and researching on his interests broadly encompassed by ‘exceptional human experiences’, entailing the aim to identify a unification between ostensibly disparate anomalous experiences. This would include, but is not limited to, resonances between the psychical research programme of ‘survival’ (near-death experiences, mediumship, reincarnation), parapsychological phenomena (e.g. precognition), and ufological investigation (including alien abduction experience) and other entity encounters.

While his lens is heavily non-reductively neuroscientific, and central angle of inquiry is how such experiences may be evinced by or intersect with psychedelic compounds, his methodological approaches are largely qualitative. Whereas such subject matter is firmly within the realms of high weirdness, it is simultaneously of the most intimate nature – complementing the far out with the fundamentally deeply within. These transpersonal phenomena still retain deep ramifications for interpersonality, where exposure to the other world has the capacity to re-model one’s interpretation of this world, through loosening otherwise encumbering prior beliefs about life toward its own inherent mystery. Though such experiences’ potential for addressing the meta-crisis is an open question, their (not mutually exclusive) implications for personal meaning crises are manifest.

Pascal has presented at the largest European conference on psychedelics, Breaking Conventions, and has been invited to give talks for private symposia like the Tyringham Initiative, which aimed to understand the entity encounter, and give keynotes such as for the Institute of Psychedelic Therapy. He has published multiple journal articles, including some of the most read articles in Frontiers in Psychology, and is the program lead of the ALEF Trust’s certificate in Psychedelics, Altered States and Transpersonal Psychology. He was also PA to the chair of the Parapsychological Association and was the 2020 recipient of the Schmeidler Outstanding Student award.
