He has made three films, and educational slide shows, and he is interested in theatre and cinema for children.


Prof Gunter Schumann gunter

The aim of Professor Schumann’s research is to improve diagnostic and treatment of mental disorder through stratified medicine. As Director of the Centre for Population Neuroscience and Stratified Medicine (PONS) at the IoPPN, King’s College London, he has developed a broad scientific network of international collaborators, who coordinate large scale neuroimaging studies in Europe, China, India and the U.S., to combine state of the art clinical neuroscience and epidemiological techniques with expertise in computer science and biostatistics.

His general research interests are in etiological and diagnostic stratification of psychiatric disorders to identify neurobehavioural phenotypes, which allow the development of predictive and prognostic biomarkers. His group thus works on the identification of neurobehavioural mechanisms of psychiatric disorders, including addictions. He pursues an interdisciplinary approach, using neuroimaging, functional genetic and epigenetic methods as well as molecular biological and bioinformatic techniques.

He coordinates the longitudinal imaging genetics cohort IMAGEN ‘Reinforcement-related behaviour in normal brain function and psychopathology’, and co-coordinates the cVEDA – project, an international Consortium on Vulnerability to Externalizing Disorders and Addictions. He is in the steering group of the imaging meta-analysis consortium ENIGMA and leads the AlcoGen consortium on genetics of alcohol drinking.


Prof Gareth J Barker gareth-barker

Professor Barker has worked in Magnetic Resonance Imaging research as applied to neurological and psychological disorders for over 25 years.  In the neurological field, his particular interests are in multiple sclerosis, epilepsy and neurodegenerative disorder; in psychiatry, he has interests in schizophrenia, bipolar disorder and depression. In parallel, his work also involves healthy controls, and has applications in the more fundamental questions of brain structure and function.

Much of his work has been on technique development, both for image acquisition and processing, and on the optimisation of protocols that make these techniques applicable to patient populations.  He currently holds an ethical approval for the development and optimisation of such scanning techniques in normal controls, along with a separate approval to allow the further optimisation sometimes required to make the techniques acceptable to clinical patients. He has a particular interest in quantitative MRI techniques; these include relaxation time measurements (which can probe the molecular environment of water within tissue (and in certain circumstances can reveal information such as the myelin water fraction)); magnetization transfer (another marker of myelination), perfusion (quantitatively and non-invasively measuring blood perfusion) and diffusion tensor imaging (providing a probe of the structure and integrity of neuronal tissue)


Dr Sylvane Desrivières Sylvane-Desrivieres-683x1024

Over the course of her career she has applied expertise in genetics and molecular and cell biology to understand how gene activity controls biological functions in organisms and systems of increasing complexity, from individual cells and unicellular organisms to organs, such as the mammary gland, and finally to the human brain.

Since little is known about the genetic bases of brain structure and function, she has combined the tremendous advantages of magnetic resonance imaging (MRI) with genetics and molecular biological approaches to investigate brain-behaviour relationships and identify genes influencing brain development and function, focusing on typically developing individuals. She applies MRI to discover the genetic roots of neuroanatomic, neurophysiological and cognitive traits that may be disrupted in individuals suffering from major mental illnesses. Another aspect of her work is aimed at overall better understanding of the etiology of addiction to alcohol and other drugs and her research helps defining risk factors for alcohol-use disorders later in life, which is fundamental for the prevention of alcohol abuse in adolescents and treatment of alcoholism, both major unmet challenges affecting our health care system and society alike.

Dr Meera Purushottam IMG-20190220-WA0017_2

Dr Meera Purushottam is senior geneticist at the Molecular Genetics Laboratory  at NIMHANS where the focus has been the genetic basis and correlates of psychiatric and neurological diseases.   The laboratory is  the testing ground for many clinicians who base their post graduate and doctoral thesis dissertations on wet lab experiments carried out under her supervision. Her work  has  focused on trying to understand the influence of gene variants on disease presentation and response to drugs. Cells derived from patients have been used to unravel disease mechanisms better, while whole exome studies have helped to identify rare risk variants in severe mental illness in patients. She is in charge of genetic testing for early onset neuromuscular and late onset movement disorders. She is interested in  understanding the biological implications of genetic variants at the level of the patient, the tissue and the cell. The effect of the environment on the DNA methylome is an area of specific interest.
