- Theory of exchange interactions in magnetic materials based on the density functional approach.
- Development of efficient computational schemes which combine the precision of first-principle band-structure schemes with the complex treatment of electron-electron correlations for d- and f-electron systems (LDA+U, LDA+DMFT).
- New generation of continuous time quantum Monte-Carlo methods for multiorbital impurity problem.
- Investigation of non-local correlation effects in low-dimensional quantum systems within fully renormalized dual-fermion perturbation.
