Parasite manipulation of host behavior

Jason Keagy

Assistant Research Professor of Wildlife Behavioral Ecology
Cognitive ecology (with studies at genome, individual, and species levels). I am particularly interested in applications for solving wildlife management problems

Todd Lajeunesse

Professor of Biology
Microbial Ecology and Evolution

Tracy Langkilde

Professor of Biology; Dean of the Eberly College of Science
The interface of ecology and evolution to understand how an organism's traits are matched to its environment and responds to novel selective pressures imposed by global environmental change, and the consequences of this adaptation.

Jesse Lasky

Associate Professor of Biology
Ecological and evolutionary genomics, genetic and ecophysiological basis of adaptation to environmental stress, evolutionary ecology of biological complexity.

Margarita Lopez-Uribe

Assistant Professor of Entomology
How environmental change and human management shape bee health and long-term persistence of their populations in agricultural areas.

Professor of Biology
The study of biodiversity in threatened ecosystems, the effects of human-modified landscapes on wildlife, and behavioral ecology of sciurids. Dr. Mahan teaches introductory biology, environmental studies, field ecology, and evolution.

James Marden

Associate Director of Operations, Huck Institutes of the Life Sciences; Professor of Biology
How physiological variation within species affects their ecology and evolution. Primarily with insects, but recently also with plants, and a particular interest in allelic variation in the pathogen resistance genes of tropical trees.
