Area of Interest
The focus of my research is to understand how different neurotransmitters and hormones help animals successfully choose mates, raise young, escape from predators, and survive harsh winters and other challenging conditions. The hormone and neurotransmitter pathways I study are very similar in all vertebrate animals, from fish to birds to mammals, so sparrow research can help us understand how these systems work in humans and other animals. One of the major areas of my research is the stress response. While stress helps animals and humans survive and cope with challenges, too much stress is bad and causes health problems. Yet we still don’t have a clear understanding of how and why stress switches from being helpful to harmful, or why some individuals, or some species, are relatively resilient to the negative effects of stress while others are more vulnerable. To address these questions, my research uses a combination of lab and field studies, and techniques from hormone sampling to brain imaging.
