Research Interests:

The research in our lab includes basic research in molecular evolution. One of the major projects over the past several decades has been to characterize the organisms and nucleic acids preserved in glacial ice, primarily from Antarctica. One focus has been on accretion ice from subglacial Lake Vostok, one of the largest and deepest lakes in the world, which lies under 3.5 km of glacial ice. It has been covered by ice continuously for at least 14 million years. Nevertheless, we discovered more than 3,000 unique species of organisms in the accretion ice formed from Lake Vostok water. This represents a novel environment and ecosystem, and has been used to predict similar environments in the Solar System. We also have performed extensive studies of ribosomal RNA genes in plants, fungi, and bacteria, which has allowed many predictions about the evolution of these genes. Many of these loci contain introns. We investigated these introns, and have summarized the evolution of these introns within these loci. While group I introns are found frequently in these genes, group II and spliceosomal intron are also found occasionally. The rRNA gene loci appear to be active sites of intron evolution.
