James Marden, Ph.D.
My research interests are primarily in the areas of physiological ecology, functional genomics, evolutionary ecology, and behavior.
In the most general terms, I am interested in how animals work and why they work that way. In other words, I investigate mechanistic details of animal physiology in an ecological and evolutionary context. I work primarily with insects because they are readily available, fantastically diverse, and ecologically/economically important. Work in my lab is often what is called integrative biology, as we aim to discover the relationships between molecular level phenomena, cellular and tissue physiology, whole organism function, behavior, and ecology.
Projects presently underway in my laboratory examine functional genomics of butterflies in a well studied metapopulation, and intraspecific variation in flight performance in the dragonfly Libellula pulchella. Other recent work has examined the evolution of insect flight using stoneflies as model organisms, and the genetic bases of performance variation in free-flying Drosophila melanogaster.
