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
