Dimitra's research spans Analysis and Numerical Analysis and Scientific Computing of PDEs and Stochastic PDEs: Ito and Malliavin calculus for stochastic PDEs, Finite Element Methods, Finite Difference Schemes, Discontinuous Galerkin Methods, Deterministic and Stochastic Non-linear Partial Differential Equations, Applied Functional Analysis, Multi-Phase Materials, Underwater Acoustics, Aeroacoustics. Numerical Analysis of PDEs-SPDEs: Dimitra examines existence and uniqueness of numerical solutions, and a priori, a posteriori error estimates for initial and boundary value problems for evolutionary PDEs such as Heat, and Schroedinger equations (underwater acoustics and aeroacoustics). The numerical solution of the approximating schemes is implemented by Fortran codes. Furthermore, Dimitra analyzes continuous and DG finite element methods for non-linear Stochastic PDEs stemming from phase separation (multi-phase materials). Analysis of PDEs-SPDEs: Ito and Malliavin calculus for nonlinear stochastic partial differential equations. Dimitra also works on the asymptotic analysis and dynamics of stochastic and deterministic problems in phase transitions such as the stochastic and deterministic Cahn-Hilliard and Allen-Cahn equations, the free boundary Stefan problem of Ostwald ripening, the volume preserving mean curvature flow and the stochastic motion under mean curvature flow. In addition, Dimitra considers certain Riemann-Hilbert problems arising from non-linear PDEs such as the NLS equation and studies rigorously the long time asymptotics of solutions.
