Research Assistant; Mathematics and Physics Tutor

Nazarbayev University

Research university in Astana, Kazakhstan.

Apr 2022 — Jun 2026

Conducted numerical-model validation and discrepancy analysis for research; also tutored a student in calculus and physics.

• Analyzed reaction-diffusion models and compared analytical results with numerical outputs produced in MATLAB. • Validated computational results by checking consistency between theoretical predictions, numerical simulations, and expected model behavior. • Investigated discrepancies between methods, identified possible causes, and summarized conclusions for research discussions and reports. • Compared analytical predictions with COMSOL simulation results for a physical modeling project and interpreted differences between approaches.
