MA913: Scientific Computing

Research Interests:

My research focuses on the development of numerical methods and mathematical tools to analyse stochastic systems. Applications include fluid dynamics and turbulence, atmosphere and ocean dynamics, and biological and chemical systems. My work concentrates on the prediction of pathways and rates of occurrence of rare and extreme events in realistic complex systems, to develop numerical methods for their simulation, and to quantify the effects of random perturbations on the system's long term behavior.

Keywords: Applied and computational mathematics - Rare events, fluid dynamics and turbulence, large deviation theory, metastability, non-equilibrium statistical mechanics, active matter
