Diederick Stoffers
Date and place of Birth: 2nd of May 1974; Bussum, The Netherlands
ISI Researcher ID: F-3762-2010
Brief Curriculum Vitae
Diederick Stoffers was trained in psychology with a specialization in clinical neuropsychology and psychobiology and received a PhD in clinical neuroscience from the faculty of medicine. After a two-year post-doc fellowship in the USA he returned to the Netherlands and is currently a post-doc in the Department of Sleep and Cognition at the Netherlands Institute for Neuroscience of the Royal Academy of Arts and Sciences under department head Eus van Someren.
His expertise/relevant skills cover neuropsychology, neurodegenerative diseases and neuroimaging, with a particular emphasis on the acquisition and analysis of structural and functional imaging data for biomarker development. Also, he is a specialist in creating and maintaining the ICT infrastructure needed for large-scale neuroimaging analyses. He has published in high-ranking journals and has lately seen a steady increase in number of citations (h-factor 10).
His major interest is large-scale networks in the human brain and their role in clinical deficits in neurological and psychiatric patients; he would like to combine different imaging techniques and modalities to study brain disease. An integrated approach should provide valuable insights into the relation of changes in brain morphology, anatomical connectivity and functional connectivity to changes in neuronal networks and their pathophysiological role in brain disease and lead to the development of reliable disease state, rate and trait imaging biomarkers.
His present work mainly focuses on insomnia, a highly common disorder with a profound socio-economic impact. A major part of his activities involve preparations for an imaging study in a large cohort of insomnia patients (N~200) that will be selected through the Sleep Registry (www.sleepregistry.eu), a large database of sleep phenotypes of many volunteers that was initiated by department head Eus van Someren. Multi-modal imaging of such a large cohort should facilitate progress in the development of biomarkers for insomnia and the understanding of underlying brain mechanisms, ultimately leading to effective, rational treatment and prevention of this debilitating condition .
