Research
My research focuses on the stochastic processes exhibiting long-range dependence both in one- and higher-dimensional settings, with particular emphasis on models associated with the Dickman distribution. I am also interested in the application of higher-order spectral analysis to the study of complex stochastic models, as well as in limit theorems arising under long-range dependence.

Teaching
I have supported multiple undergraduate modules as a Graduate Tutor in the School of Mathematics, Cardiff University, including:
- Foundations of Mathematics I (2023-2025)
- Foundations of Mathematics II (2024-2026)
- Introduction to Probability (2025)
I also serve as a Mathematics Support Tutor, providing assistance to students across multiple departments in addressing mathematical problems.
