Marc Guitart-Masip is a researcher at the Aging Research Center, Karolinska Institutet, Sweden where he has established himself as an independent scientist. In parallel, he works as a Psychiatrist consultant at the Affective outpatients unit at Psykiatri Nordväst, Stockholm, Sweden.
He graduated in medicine in 2002 at Universitat Autònoma de Barcelona and obtained a PhD in Neuroscience at the same university in 2006. During his PhD, he performed experiments in the field of Behavioral and Molecular Pharmacology using animal models of vulnerability to addiction. After obtaining a PhD, his interests expanded to Cognitive Neuroscience and between 2008 and 2012 he was a postdoctoral fellow, first at the Institute of Cognitive Neuroscience, and thereafter at the Wellcome Trust Centre for Neuroimaging, at University College London (UCL). Marc was appointed Associate Professor of Neuroscience at Karolinska Institutet in 2018.
He combines behavioural approaches, computational modelling, pharmacological manipulations and imaging techniques such as fMRI, PET and MEG.
