Research Interests:
Primary research interests are with the various insects and ticks that can transmit disease organisms to humans, livestock and wildlife.  Specific interests center on the acquisition and maintenance of pathogenic organisms by vector arthropods using a population dynamics approach and examining the effects that host blood components, such as antibody or drugs, can exert on both vector arthropods and the growth characteristics of pathogens developing within vector arthropods.
