“At the 24-hour time point, there’s really no ketamine left in the body at all. The ketamine’s gone, they haven’t been high for 20, 22 hours . . . but they’re still not depressed. What that shows is that the ketamine has changed something in their brain.”
— Dr. Suresh Muthukumaraswamy
Dr. Suresh Muthukumaraswamy completed his PhD in Psychology at the University of Auckland in 2005, after which he joined the newly established Cardiff University Brain Research Imaging Centre as a postdoctoral fellow. While at Cardiff, he started research work with psychedelics in 2011 in collaboration with Professor David Nutt and Dr. Robin Carhart-Harris, investigating the neuroimaging correlates of the psychedelic drugs psilocybin and LSD. In 2014, Suresh received a prestigious Rutherford Discovery Fellowship and returned to the University of Auckland where he works in the School of Pharmacy at the Faculty of Medical and Health Sciences and leads the Auckland Neuropsychopharmacology Research Group.
Suresh’s main research interests are in understanding how therapies alter brain function and behavior and in testing methodologies to measure these changes in both healthy individuals and patient groups—particularly in depressed patients.
At the University of Auckland, he has conducted clinical trials in depressed patients involving ketamine, scopolamine, and transcranial magnetic stimulation. He has received several Health Research Council of New Zealand research grants to support this work, including a grant to investigate the effects of microdoses of LSD on brain and cognitive function. Suresh has published 117 papers, with his work receiving 8000+ citations.
This special episode of the podcast is a live recording from an event hosted by the Edmund Hillary Fellowship (EHF). EHF began in 2016 as a pilot immigration program and has matured into a fellowship of more than 500 technologists, creatives, investors, entrepreneurs, educators, and systems designers, committed to New Zealand as a base camp for global impact. From more than 50 different nationalities, including New Zealand, fellows span a range of high-value sectors: media, education, cleantech, venture capital, and mental health initiatives/research just to name a few.
EHF and its fellows aim to make a meaningful impact in New Zealand/Aotearoa with projects that often have global applications.
