Chris Letheby

Dr Chris Letheby is a Senior Lecturer in the Discipline of Philosophy at the School of Humanities, The University of Western Australia (UWA), specializing in neurophilosophy and psychedelic studies. His work bridges empirical neuroscience with philosophical inquiry, focusing on the epistemic validity of psychedelic experiences and their therapeutic applications.

Letheby holds a PhD in Philosophy from the University of Adelaide (2017), where his doctoral research examined psychedelic transformation. His academic trajectory includes a postdoctoral position at the University of Adelaide (2019-2022) prior to his current appointment at UWA.

His research centers on reconciling traditional spiritual interpretations of psychedelics with scientific naturalism, investigating transformative practices, self-awareness mechanisms, and the philosophical foundations of psychedelic therapy. His neurophilosophical approach integrates findings from cognitive neuroscience with conceptual analysis to address questions about consciousness, epistemology, and mental health.

Recent publications demonstrate a cohesive trajectory exploring psychedelic epistemology and therapeutic mechanisms. His 2021 monograph established foundational frameworks for naturalistic spirituality, while 2024 works address contemporary challenges in psychedelic science including fear of death reduction, methodological disputes in mystical experience research, and clinical implementation frameworks.

Letheby's scholarly contributions have been recognized with multiple prestigious awards:

• Faculty of Arts Prize for Outstanding Research by an Early Career Researcher (2022)
• School of Humanities Early Career Award for Best Publication in 2021 (2022)
• School of Humanities Early-Career Research Award (2022)
• Senior Researcher Visiting Fellowship at Antwerp Center for Philosophical Psychology (2022)

He actively mentors PhD students at UWA and pioneers curriculum development, notably creating PHIL3009 The Philosophy of Psychedelics (launching 2025)—the Southern Hemisphere's first undergraduate course on this topic. His interdisciplinary collaborations with neuroscientists and psychologists exemplify his commitment to integrating philosophical rigor with empirical research, advancing both theoretical understanding and clinical applications in mental health.

Letheby's work contributes significantly to Sustainable Development Goal 3 (Good Health and Well-being) through its implications for psychedelic-assisted therapy. His research profile shows strong international engagement, evidenced by translations of his work, global conference participation, and collaborative projects across neuroscience and philosophy disciplines.
