Amanda Feilding is the founder and director of The Beckley Foundation (beckleyfoundation.org), which she set up in 1998, following a lifelong interest in consciousness research. In order to carry out the research, she has built up collaborative partnerships with leading scientists around the world, with whom she works on a wide range of projects investigating the neurophysiology, pharmacology and subjective effects of psychoactive substances such as cannabis, psilocybin, MDMA, LSD and 'legal highs'. Her research work elucidates the neuroscientific underpinnings of consciousness, investigates how psychoactive substances work and how consciousness may be enhanced, and explores new potential therapeutic applications.
