Scientific Interests  

Research 

Currently working with the project REGAL - Regularized density-functional analysis, a European Research Council (ERC) Starting Grant.

Link to project website, uni.oslomet.no/regal/

I am at the moment working on applying and analysing methods from DFT on a quantum electrodynamical system. I am also working on an application of Moreau-Yosida regularisation of DFT to periodic systems (crystalline materials).

  • REGAL

    The project researches Moreau-Yosida regularization in density-functional theory (DFT). Of particular interest is Kohn-Sham-DFT that uses one-particle orbitals to represent the one-body density.
