I have been an associate professor at the Department of Mathematical Analysis at Odesa I.I.Mechnikov National University in Ukraine since 2005, where I have worked since 2002. My research expertise lies in the mathematical modeling of complex systems such as computer, environmental, and economic systems. I hold a PhD in Physics and Mathematics which I obtained in 2004. In recent years, I have focused on the field of distributed ledger technology (DLT) and have been involved in numerous projects related to decentralized public and private systems.
