Background and Interests
 
My current research interests are: Nematode-bacteria symbiosis. Multitrophic interactions in agricultural systems. Entomopathogens and biological control. Biodiversity, ecology,and evolution of entomopathogenic nematodes. nematode systematics (relationships between morphological and molecular evolution). Current phylogenetic studies of nematodes involve the use of nucleotide sequence data (nuclear and mitochondrial genes) and morphological traits to infer relationships for insect-parasitic, entomopathogenic and free-living nematodes. Another area of interest is the biodiversity of nematodes and their role in ecosystem function. I am actively engaged in survey and inventory projects in different geographic regions of the world, which allow me to make significant contributions toward biological conservation and restoration efforts. These projects require continued research into improving molecular techniques by which nematode species are recovered. Additionally, I' m interested in studying the ecology and genetics of nematode populations from agricultural and natural ecosystems. Host-parasite relationships and interactions (including plant and insect-parasitic nematodes), such as phoresis, facultative, obligate parasitism, and pathogenesis. I also have an active research program on insect pathology and the use of entomopathogenic nematodes as biological control agents. The overall objectives of this program are to develop entomopathogens as effective biocontrol agents against major agricultural pests, and to develop a basic understanding of the ecology and behavior of insect parasitic nematodes.
