Education:
BS in Theoretical Physics, Taras Shevchenko National University of Kyiv, Ukraine
MS in Theoretical Physics, Taras Shevchenko National University of Kyiv, Ukraine
I am a PhD student in Physics department, where I am working with Dr. Lyubov Titova. My research interests focus on finding alternative sources of energy by investigating the properties of materials. Currently, my project is terahertz spectroscopy of 2D materials; nonlinear optical properties of 2D nanostructures. Since 2018, I am member of Arts&Science Graduate Advisory Council. In 2018 I got an Outstanding Mentor Award from Department of Physics.
