Suresh 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 post-doctoral fellow. In 2014 Suresh received a Rutherford Discovery Fellowship and has returned to Auckland where he works in both the School of Pharmacy (Faculty of Medicine and Health Sciences) and School of Psychology (Faculty of Science).

Suresh’s main research interests are in understanding how therapies alter brain activity and in developing methodologies to measure these changes in both healthy individuals and patient groups. His previous studies have involved a range of compounds including hallucinogens (ketamine, LSD, psilocybin), anaesthetics (propofol, dexmedetomidine), anti-epileptics (vigabatrin, perampanel, tiagabine) and GABA-enhancers (zolpidem, gaboxadol). Suresh’s research has used a wide-range of neuroimaging techniques including magnetoencephalography, electroencephalography, functional magnetic resonance imaging and magnetic resonance spectroscopy.
