The main focus of my research is on multilevel Monte Carlo and finite element methods for the solution of PDEs with random coefficients and spatial white noise driven SPDEs. Currently, the application in mind is the quantification of uncertainty in brain fluid simulation.
Main research interests:
- Low-precision numerical solvers for PDEs
- Finite Element Methods for PDEs
- Multilevel Monte Carlo and Multilevel Quasi Monte Carlo
- Numerical Methods for Spatial White Noise driven SPDEs
- PDEs with Random Coefficients
- Uncertainty Quantification for SPDEs
- Mathematical Modelling of the Brain Physiology
- Numerical Linear Algebra
- Deflation for Complementarity Problems
