Biography

Dr. Irene Sargiannidou was born in Veria, Greece. She completed her studies in the United States of America where she obtained her BSc degree in Biology from Plymouth State University, NH (1994) and her PhD degree in Molecular Pathobiology from Drexel University, Philadelphia, (2003). She has been employed by the Cyprus Institute of Neurology and Genetics since 2005, as a post doctoral fellow in the Neuroscience Lab. She worked on generating transgenic mouse models that express Cx32 mutations in both Schwann cells and oligodendrocytes. She analysed both CNS and PNS myelination defects in mouse models of inherited neuropathy. Her current research focus is the development of gene therapy approaches for inherited neuropathies. Besides her productive research work, she is currently supervising 3 PhD and 2 MSc students.
