She was born in Athens, Greece in 1960. She graduated from the School of Medicine, University of Patras in 1984 and was trained in Neurology in Evagelismos Hospital (1987 - 1990), followed by subspeciality training in Clinical Neurophysiology in St. Thomas' Hospital, London (1990-1994). She was appointed Lecturer of Neurology in the Univerisity of Patras in 1998, Assistant Professor in 2003 and Professor in 2010. Since September 2016 she is the Director of the Neurology Department of the University Hospital of Patras. She hold a PhD thesis from the University of London (Guys' and St. Thomas' United Medial and Dental Schools) entitled " F chrono-dispersion and F tacheodispersion: A study of conduction properties of motor nerve fibers in normal and pathological conditions". She is currently a Member of Greek Neurological Association and of Greek Neurophysiological Association (former vise-president). She has participated in neurophysiological projects funded by Special Trustees of St. Thomas Hospital & British Polio Society, and currently participates in  “En-noisi”, a Greek project of artificial intelligence for the early diagnosis, follow-up and support of patients with mild mental disorder and dementia and  in “No Tremor”, a collaborative project financed from EC on neuromuscular model of Parkinson disease. She is member of editorial committee in 1 journal, invited reviewer in 30 international journals and author of 131 peer reviewed articles (total impact factor 480, citations in scopus 2350 and H index 21)

-She was the Supervising Professor in 4 successfully completed   Ph.D. theses in the Medical School of the University of Patras. The first thesis was referred to neuroprotection from chemotherapy induced neuropathy (completed in 2006). The second one dealt with abnormalities of autonomic nervous system in patients with epilepsy (completed in 2009). The third thesis examined the effect of deep brain stimulation on the autonomic nervous system manifestations of patients with Parkinson disease (completed in 2010). The forth thesis studied muscle atrophy and motor unit numbers in patients after stroke (completed in 2016).

-She was a Member of the Advisor Committee in 6 Ph.D. completed theses.
