Research
Reseach Interests I am interested in mathematical applications related to the development of finite element discretizations, more specifically the mixed finite elements and the discontinuous finite elements, for neutral particle transport. In particular, the subjects I am interested in are listed below:
- Numerical analysis;
- A posteriori estimation;
- Domain decomposition;
- Model order reduction.
During my PhD, I studied various multiscale finite element approaches for advection diffusion problems.
