Research

My research combines high-fidelity CFD, in-vitro validation, PIV-based flow measurement and reduced-order modeling to make complex flow systems more interpretable and useful for engineering and clinical decisions.

• Biofluid mechanics. Upper-airway airflow, obstructive sleep apnea, pseudoaneurysm treatment, ureteral stents, thrombosis modeling and patient-specific medical-twin workflows.
• Turbomachinery and propulsion. Rim-driven pumps and propellers, drainage and booster pumps, duct and blade optimization, cavitation, erosion, hydraulic performance and CFD–PIV validation.
• Data-driven flow modeling. Koopman theory, dynamic mode decomposition, CNN-based autoencoders, and reduced-order models for faster prediction, diagnosis, and design exploration.
