As a comparative pathobiologist/protistologist, my laboratory specializes in the study of obligate intracellular parasitic organisms of the phylum, Microsporidia, in all types of hosts including invertebrates, vertebrates, and humans.  We study many aspects of the biology of the microsporidian parasites especially their ultrastructure, specialized and/or unique organelles, development and pathology as well as their distribution, means of transmission, and identification.  We study these parasites in vivo and/or in vitro in cell cultures as the microsporidia cannot be cultivated outside host cell cytoplasm.  Our understanding of animal infections provides insights into human infection, as well as epidemiology, reservoir hosts, and transmission to humans.
