Research Interest
I have two major background domains: Applied Mathematics and Physics. Therefore, my research interests encompass research on Dynamical Systems, Koopman Operator, Data-Driven Analysis of Complex Systems, Machine Learning, Aero Dynamics, Fluid Dynamics, Numerical Analysis, Linear Algebra, High-Pressure Science/Geophysics, Astrophysics, Weather Forecasting.
My primary Ph.D. project investigates how to enhance the optimization of aerodynamic structures (airfoils and aircraft) in unsteady flows using Dynamic Mode Decomposition (DMD). As a secondary project, I have been working on analyzing tidal flows through the Strait of Gibraltar using DMD and Koopman operator analysis.
