I graduated from the Department of Biology at the University of Patras (1976-1980). Then, I received my Ph.D. degree [as a scholar of the (Greek) State Foundation of Scholarships (IKY) and the Department of Biology at the University of Patras] from the same Department at the University of Patras (1987). Since 2006, I am Associate Professor of Physiological Psychology. My research interests are focused on the study of dopaminergic interactions with other neuroactive and /or psychotropic substances (thyroid hormones, somatostatin, opioids, psychostimulants), involving the anatomical, neurochemical, pharmacological and behavioural aspects of brain function.
- University of the Patras, Dept. Biology (1989)
- As postgraduate researcher in the Lab. of Human & Animal Physiology
- University of Crete, Dept. Psychology (1989 – Today)
- As adjunct instructor initially (1989-1992) and as a Faculty Member (1992-today)
