Christos Papadelis is Instructor in Pediatrics at Harvard Medical School, Research Associate at Children’s Hospital Boston and Manager of the BabyMEG laboratory. He has received the Diploma in Electrical Engineering from the Aristotle University of Thessaloniki, Greece, in 1998, and his MSc and PhD in Medical Informatics, in 2001 and 2005 respectively, from the same institute. During his graduate studies, he worked in a number of research projects funded from the European Union and the Greek Secretariat for Research and Technology. After his PhD graduation, he worked as Post-Doc Researcher in the Laboratory of Human Brain Dynamics at Brain Science Institute (BSI) of RIKEN, Japan, from June 2005 to August 2008, and in the Center for Mind/Brain Sciences (CIMeC) of University of Trento, Italy, from September 2008 to August 2011.

His main research activities include:

Presurgical Mapping in Childhood Epilepsy: A large proportion of pediatric epileptic patients become medically intractable and require resective surgery. To be successful, epilepsy surgery requires a comprehensive preoperative evaluation for defining the epileptogenic zone. A battery of presurgical diagnostic tests is used to assess the epileptogenic zone. However, the results of these tests are often insufficiently concordant or inconclusive. Dr. Papadelis works on the development of a non-invasively acquired robust biomarker that identifies the epileptogenic zone and eventually improves the outcome of surgical treatment in pediatric patients with epilepsy. 

Anatomical and Functional Deficits in the Brain of Children with Cerebral Palsy: Although cerebral palsy is among the most common causes of physical disability in early childhood, we know little about the functional and structural changes of this disorder in the developing brain. Dr. Papadelis investigates with different neuroimaging modalities whether spastic cerebral palsy is associated with functional and anatomical abnormalities in the sensorimotor network. This research has important implications for the diagnosis and the rehabilitation of patients with spastic cerebral palsy. Such interventions should be applied early in life when the brain demonstrates the ability to plasticity, allowing it to readily reorganize in the face of injury. 

Involvement of Cerebellum in the Processing of Emotions: Despite findings that a wide variety of psychiatric disorders have been associated with abnormalities in the cerebellum, this brain structure is often overlooked as a contributor to the neural basis of emotion. Dr. Papadelis’ goal is to examine the functional role of cerebellum in the processing of emotional stimuli. This kind of knowledge could aid in the development of novel therapies to detect and treat early manifestations of psychiatric disorders, such as those affecting mood and anxiety. 

Dr. Papadelis is Guest Associate Editor in the Frontiers in Human Neuroscience, Associate Editor in the Journal of Information Technology Research (JITR), Guest Editor in Biomedical Signal Processing and Control, and ad-hoc reviewer in more than twenty peer-reviewed journals such as Neuroimage, Brain Research, Journal of Sleep Research, and others. He has published more than 30 papers in peer-reviewed journals, while figures of his work have been selected as covers in scientific journals.
