My
research interests are broad, and I have published papers in ecology, taxonomy,
medical entomology, and genetics, including such taxa as frogs, bats, crickets,
mosquitoes and mites. My research
has focused primarily on the population dynamics, genetics, and evolutionary
biology of insects that affect the health of humans and other animals.
I am currently investigating the genetic differentiation and ecology of
malaria mosquitoes in Bolivia under a grant from the National Institutes of
Health. Another aspect of my
research program examines sociobiological questions in yellowjackets and fire
ants. For example, my
students and I recently completed two studies that examine genetic relatedness
and reproduction in yellowjacket nests with single or multiple queens.
Dr.
Fritz is the director of the department's Biotechnology
Center.
