About

I am a biologist with academic experience in molecular biology, behavioral research, and disease-related biological mechanisms. I completed my B.Sc. in Biology and M.Sc. in the Molecular Basis of Human Diseases program at the University of Crete, where I worked on the effects of working-memory training on anxiety behavior in mice and investigated the neurogenic role of the p75 neurotrophin receptor in vivo. I am now a PhD Candidate in the field of neuroscience in the Medical University of Innsbruck in Tyrol, Austria, investigating the role of miRNAs in nerve regeneration after peripheral nerve injury. I am excited to connect with fellow scientists and exchange ideas!
