Research and Areas of Expertise
My research involves using insects as model organisms to understand topics in ecology and evolutionary biology. Current research projects include an investigation of the genetic structure of populations of the mayfly Baetis tricaudatus in the San Bernardino Mountains, and a study of the effects of recent tree mortality caused by bark beetles on ant communities in the San Bernardino National Forest. My areas of expertise include ecology, evolutionary biology, and tropical biology, as well as zoology (with an emphasis on invertebrates).
I became interested in ecology while tromping around the Berkshire Mountains as a student at Williams College, and fell in love with tropical biology while interning for a research project in Costa Rica in 1996 and 1997. My Ph.D. dissertation at UC Davis involved significant field work in the rain forest of Costa Rica. I'm especially interested in field science, and in using insects as study organisms to illuminate important concepts in ecology and evolutionary biology.

Redands' Biology Department
The impact of the recent bark beetle outbreak on the San Bernardino National Forest is a topic of current concern, because the forest ecosystem has been dramatically altered. Insects in general play important roles in the lives of humans in Southern California, including the invasive Argentine ant, the pests that vector plant diseases such as Pierce's disease, and the honeybees that play a vital economic role as pollinators of crop plants. I am fascinated by animals of all kinds. The Biology department at the University of Redlands engages students as individuals to help them develop the knowledge base and skill sets that they need to excel in the workforce and in graduate or professional schools.
