Olena Tymoshenko

Olena Tymoshenko is a Research Fellow at the University of Oslo, Department of Mathematics, specializing in stochastic analysis and its applications. She is affiliated with the Risk and Stochastics research group and contributes to projects on robustness, asymptotic behavior, and stability of stochastic differential equation (SDE) models.

• Current Position: Research Fellow, Department of Mathematics, University of Oslo
• Previous Role: Associate Professor at National Technical University of Ukraine (2019–2023)

Research Interests: Stochastic differential equations, asymptotic behavior of solutions, mathematical finance, limit theorems, pseudoregularly varying functions, and stochastic dynamics in biological systems.

Recent Article Trends: Focus on partial differential equations driven by Lévy noise, McKean-Vlasov systems, and Brownian sheets. Applications span mathematical finance, epidemiology (monkeypox transmission), and control theory (Kalman filter algorithms).

• Teaching: Courses include Introduction to Mathematical Finance and Investment Theory (STK-MAT3700, Fall 2022) and Statistical Methods and Applications (STK4900, Spring 2023).
• Other Affiliation: Participant in the International Summer School as a student.
