Dr. Antonios Dakanalis, MD, PsyD, PhD

Dr. Antonios Dakanalis, MD, PsyD, PhD

Dr. Dakanalis is an Adjunct Senior Researcher and Contract Professor of Experimental and Clinical Psychopathology at the Department of Translational Medicine, Medical School, University of Milano-Bicocca, Italy. He is also Didactic Coordinator & Scientific Co-director for the Executive Master “Diagnosis and multidisciplinary treatment of Eating Disorders”. Dr. Dakanalis' work underpins the very first neuropsychological model of bodily self-objectification and its role in the development and maintenance process of eating disorder psychopathology and the very first application of body swapping illusion as a tool for modifying our (distorted) memory of the body in a controlled way. He has conducted several empirical investigations with large clinical populations highlighting the role of multidimensional body image in the maintenance process of eating pathology and the need for additional interventions to improve the effectiveness of existing evidence-based interventions, as well as various longitudinal studies on unhealthy weight-control behaviors used to counter distorted body representation as potential antecedents of eating and weight disorders.
