Dr Leto Kyritsi

Biologist - Bioinformatician

Leto Kyritsi studied Molecular Biology and Genetics, and obtained an M.Sc. in Biosystems and Informatics from the University of Liverpool.

In Liverpool she did protein expression research for the University's Department of Medicine (Oncology Research Unit and TheRyte Ltd.) where she initiated a project for modelling protein-protein interaction networks in normal vs. cancer cells as scale-free networks. She was a member of the Biocomputation and Computational Biology Group, led by Ray C. Paton, with whom she collaborated for the "Multidisciplinary Approaches to Theory in Medicine" book series (Elsevier Science).

She has a PhD from the Department of Chemistryof the Aristotle University of Thessaloniki. Her doctoral research was carried out under the supervision of Professors Theodora Choli-Papadopoulou and Anastasia Pantazaki (Dept. of Chemistry) and Stergios Logothetidis (Dept. of Physics). Her research entailed investigating the effect of ultradilute solutions on cells and tissues of various types, by means of biochemical and biophysical methodologies.
