Brief synopsis of current research:
Phylogeny and ecology of ciliated protozoa. The main goal of my research is to identify the roles that ciliated protozoa perform in a variety of ecosystems, from freshwater and marine planktonic ecosystems to tropical soils. In addition to devising new methods for effectively sampling ciliates from these ecosystems, we must know something about the biodiversity of this group. My students and I have devised novel staining procedures that allow is to quantify and describe species diversity from a variety of habitats. By selecting "typical" species from this diversity, we are also constructing a phylogeny of the entire Phylum Ciliophora, now primarily using the nucleotide sequences of the small subunit ribosomal RNA gene.
