Research Interests

My research interests are centered on various aspects of avian ecology and wildlife toxicology.  Some of my recent toxicology projects included documenting heavy metal contaminants in North American gray wolves (Canis lupus) and documenting organochlorine (e.g., DDT) pesticide contaminants in dickcissels (Spiza americana).   I am currently working on collaborative projects investigating the porosity of eggshells of the brown-headed cowbird (Molothrus ater) in relation to incubation periods and brood hatching patterns.  The eggs of the brood parasitic cowbirds often hatch earlier than those of their hosts, which increases the survival of their offspring at the expense of host offspring.  We are investigating eggshell porosity as a possible mechanism by which hatching asynchrony may occur. In addition, we are investigating eggshell porosity and hatching asynchrony in house wrens (Troglodytes aedon). Since coming to Illinois Wesleyan I have involved students in all of my research projects and we have published 12 student-coauthored papers in refereed, scientific journals.
