Dr. Christos Lisgaras received his Integrated Master’s Degree in Applied Biology and Technology from the University of Ioannina in Greece and his Ph.D. in Neurophysiology and Neuropharmacology from the same institution. His Ph.D. work focused on the role of the cholinergic system in the hyperexcitability of developmental epilepsies with a particular focus on hippocampal and cortical oscillations. He was subsequently trained at the Albert Einstein College of Medicine to investigate post-traumatic electrophysiological (EEG) abnormalities and antiepileptogenic treatments as a part of a preclinical consortium, the Epilepsy Bioinformatics Study for Antiepileptogenic Therapy (EpiBioS4Rx).

Christos’ current work is focused on developing new approaches to treat epilepsy and associated memory impairments without side effects. To that end, he developed a novel closed-loop approach to stop seizures, pathological oscillations and interictal discharges in real time using optogenetics. Using this selective approach, he was able to determine a novel therapeutic role for hippocampal area CA2 in epilepsy. Also, his experience in the Scharfman laboratory made him highly interested in Alzheimer’s disease and especially the role of high frequency oscillations as a biomarker. To that end, he is using large-scale in vivo electrophysiology in different animal models of AD to search for early EEG biomarkers.     

Christos has served on committees at the International League against Epilepsy (ILAE) and he is a founding member of the Young Epilepsy Section. He has been awarded the Herbert H. Jasper Junior Investigator Travel Award and supported by the ILAE, AES, the Alexander S. Onassis Public Benefit Foundation, the Greek National Scholarships Foundation, the Bodossaki Foundation, and the World Hellenic Biomedical Association. His work is also supported by NYU’s Comprehensive Epilepsy Center FACES Pilot Research Grant to advance brain stimulation strategies in temporal lobe epilepsy.
