Theologos M. Michaelidis is Associate Professor at the Department of Biological Applications and Technologies, at the University of Ioannina and an Associated Member of the BRI. He studied Biology at the University of Athens (Greece) and obtained his PhD in Molecular Biology from the Department of Biology at the University of Crete (1992). He has made postdoctoral research at the Department of Neurobiochemistry, Max Planck Institute for Psychiatry in Munich, and at the Department of Molecular Biology of the Cell, German Cancer Research Center in Heidelberg. He was employed as a University Assistant at the Department of Neuroscience, Innsbruck Medical University, Austria (2003-2006). He has used genetically modified animals to study the mechanisms of programmed cell death in the developing nervous system. His current research is focused on the analysis of the molecular pathways determining neuronal cell death and neurogenesis in the mammalian brain, using differential screening approaches as well as stem cell and transgenic animal models.
