Biography
My research laboratory is directed toward two areas of interest: 1) the evolution
of host-parasite relationships, and 2) biology and physiological interactions between
necrophagous flies and parasitic wasps important to criminal investigations (Forensic
Entomology). My primary research interests are in the interactions that occur between
parasitic insects and their hosts. Specifically, I study the behavioral and biochemical
adaptations that result from parasitic invasions of holometabolous insects. Over
the last several years, my attention has been focused toward 5 areas: 1) parasite
regulation of host developmental and nutritional program in relation to the reproductive
strategy (gregarious versus solitary) employed by ectoparasitic wasps, 2) acquisition
of cold tolerance in ectoparasitic wasps, particularly in relation to the influence
of host species, 3) immunological responses of filth flies to parasitism by ectoparasitoids,
4) modes of action of parasitic wasp venoms, and 5) molecular cloning of venom genes
from parasitic wasps.
A new direction for my research laboratory has been investigations of physiological
interactions occurring between flies that develop on a corpse. Presently, I am examining
the physiology of maggot masses, which are large feeding aggregations of fly larvae
that form on an animal carcass during decomposition. My lab is attempting to decipher
the source of heat generation that occurs in these masses, as well as characterizing
the proteotoxic or thermal stress responses and adaptations of flies developing in
maggot masses with elevated temperatures, and determine the costs and benefits to
the life history strategies of necrophagous flies.
