The research in my lab centers around the goal of understanding evolution of land plants, following three main lines: 1) reconstructing plant phylogeny using molecular approaches, 2) investigating evolution of mitochondrial and nuclear genomes in early land plants, and 3) examining the effect of changes of the abiotic and biotic environment on plant evolution and vice versa since the origin of land plants in the mid-Ordovician. Over the last several years, we have been analyzing both gene sequences and genomic structural features to unravel diversification patterns of early land plants and early angiosperms. We have also worked extensively on evolution of group II introns in the mitochondrial genome. At present, we are continuing our work in these two areas. We also developing projects to study evolution of genetic basis of various aspects of plant-environment interaction. In the near future, we will begin working on evolution of the nuclear genome, to understand the roles of introns and transposons in genome evolution and their potential contribution to generating organismal diversity.
