Academic title: Associate Professor (2005)

Doctoral dissertation titled “Qualitative Properties of Dynamic Systems Generated by Nonlinear Partial Differential Equations with Boundary Conditions,” defended at the Institute of Theoretical and Numerical Physics of the National Academy of Sciences of Ukraine, Kharkiv, 2019 (specialization 01.01.03 – Mathematical Physics).

Differential equations with delay (memory) are at the center of my research. Such equations naturally arise in all applied problems where the finite speed of signal propagation is taken into account and, as a result, the delay in the response of biological, chemical, and mechanical systems. I study partial differential equations and the asymptotic properties of their solutions. My most recent research focuses on mathematical models in biology. 

All results of my research (scientific publications) have been published in international mathematics journals that are included in the leading bibliometric databases Web of Science and Scopus.
