Research interests:
I am interested in numerical methods for finding multiple solutions of topology optimization problems.
My main focuses are
- PDE constrained optimization
- Topology optimization
- Numerical analysis of finite element methods
- Computing multiple solutions of nonlinear PDEs
A FEniCS implementation of the deflated barrier method can be found at my Bitbucket repository (GitHub mirror).
Here is a MATLAB implementation of deflation.
