Maria Andrianova

Professor Georgii Bazykin

Maria graduated with honors from the Faculty of Bioengineering and Bioinformatics of Moscow State University in 2012. Her diploma thesis was about population genetic analysis of highly polymorphic sea squirt Ciona savignyi. In postgraduate studies, Maria continued analyses of highly variable species on the fungi Schizophyllum commune. In 2015, Maria shifted her focus of interests to mutagenesis, repair systems in cells and cancer genetics. Her projects covered various topics, such as efficiency of repair system during replication in cells, mutagenic activity of APOBEC enzyme and properties of hypermutable brain cancers. In 2019, Maria defended a thesis on the topic “Characteristics of point mutations in human cancer cells”.
