My research interests refer on one hand to the disintegration of heavy and superheavy nuclei by means of alpha and cluster decay. For the description of these phenomena in terms of clustering amplitudes, half-lives and spectroscopic factors, I employ microscopic as well as phenomenological models. The other topic I am interested in is the phenomenological description of the collective excitations in medium mass nuclei using analytical and algebraic methods. In particular, I explore the effect of various additional degrees of freedom such as rigidity of nuclear surface, energy dependence or the fragmentation of the collective potential, on the collective nuclear properties.
