Biography

Prof. Toulopoulou earned her Ph.D., under the supervision of Prof. Sir Robin Murray and Prof. Robin Morris, at the University of London in 2001. She completed most of her postgraduate training and her early working career at the Institute of Psychiatry, Psychology, and Neuroscience, King’s College London, UK, where she was affiliated until recently. She came to Turkey in 2015, after a short period at the University of Hong Kong as the Head of Psychosis Lab, to lead Bilkent University’s developing Psychology Department, where she was the Chair and the Psychology Graduate Program Head until 2019. Prof. Toulopoulou has been continuously funded since 2011 by national funding agencies (e.g., Economic and Social Research Council (U.K.), Research Grants Council (H.K.), the National Institutes of Health (USA), and the Scientific and Technological Research Council (Turkey)) on studies dedicated to understanding the cognitive and genetic mechanisms that influence an individual’s susceptibility to develop serious mental illness. Since 2012 she has been a member of the genus consortium (genus.mgh.harvard.edu), a collaborative schizophrenia neurogenetics project funded by the National Institute of Mental Health (NIMH), which aims to increase our understanding of the underlying mechanisms of impaired brain structure and function in schizophrenia, by combining brain imaging and cognitive measures with genotype data. She recently joined the enigma network (enigma.ini.usc.edu/), which brings together researchers in imaging genomics to understand brain structure, function, and mental illness, based on brain imaging and genetic data. Previously Prof. Toulopoulou had been the lead scientist for the ‘genes and cognition’ work package of the European Community’s 6th Framework Program and a partner in the European Community’s 7th Framework Program. She regularly reviews for numerous journals and serves as an ad hoc fellowship and grant reviewer for the Wellcome Trust and the Medical Research Council (MRC), among other councils. Finally, Prof. Toulopoulou was a panel member for the European Research Council’s (ERC) advanced research grants and a deputy panel chair for ERC’s consolidator research grants.


Research

The work of Prof. Toulopoulou’s lab is interdisciplinary and focuses on understanding the cognitive, neurobiological, and genetic mechanisms that influence an individual’s susceptibility to develop mental disease or build resilience. It is hoped that with a better understanding of the brain mechanisms that increase vulnerability, prevention may be possible. For example, insights on how cumulative genetic risk, in tandem with environmental risk, is physically imbedded in the developing brain can lead to new treatments and can offer us the opportunity of making new and meaningful interventions by removing or compensating for the genetic and environmental effect.

Prof. Toulopoulou is pleased to consider applications from talented prospective PhD students and postdocs.
