My research employs molecular and non-molecular tools addressing plant systematics questions at both higher and lower taxonomic level as well as molecular mechanisms underlying organellar genome evolution in plants. The bulk of my research is centered on the systematics and molecular evolution of Convolvulaceae (morning-glory family) in general and, more particularly, on a parasitic genus Cuscuta (dodders) found within that family. Convolvulaceae are one of the very few flowering plant families showing substantial structural differences in otherwise highly conserved plastid genome. The comparative approach on a broad taxon sampling within this family and in conjunction with a robust phylogenetic framework will help to address a series of testable hypotheses regarding the pattern and process of chloroplast genome evolution and their correlates at the organismal level. More broadly, I am interested in a number of other related plant evolution topics. From the systematics point of view I am mostly interested in a deep level phylogeny of land plants, in particular that of conifers and basal angiosperms. In molecular evolution field, I am particularly interested in changes that have shaped the plastid genome evolution in heterotrophic plants in general (both parasitic and mycotrophic), the shared and unique features characterizing different phylogenetic, ecological, and physiological groups of heterotrophs, as well as the extent of involvement of these very unusual plants in evolutionary phenomena such as horizontal gene transfer. I am interested in patterns of mitochondrial evolution in land plants, as well, especially in ferns and conifers.
