What does Ken do?

I study the behavioral ecology and life history tactics of a wide variety of terrestrial and marine organisms. I am particularly interested in the environmental factors that govern where organisms are found and how their dispersion ultimately influences social behavior and the timing of reproduction.

I am also concerned about environmental issues such as the establishment of marine reserves and global climate change, particularly with regards to effects on coral reefs. Click here to learn more

What is Ken up to these days?

In addition to serving as Chair of the Biology Department, in the fall of 2014 I will teach Bio 141, Investigations in Ecology and the Environment. In the spring, I will teach Animal Behavior (Bio 352). Marine Biology (Bio 221) is on tap for the fall of 2015.

About me....

I was born in North Carolina in 1958 and shortly thereafter moved to Maryland, where my father undertook his doctoral studies at John Hopkins University. In 1962 we moved to California and I grew up in the San Francisco Bay Area just as Silicon Valley was earning it's name. The first Apple computer was being built in a garage down the street from my house during that time and the orchards that I knew from my early childhood were inexorably disappearing under an ever expanding tide of concrete. I developed a love of the out of doors during summers spent living in a tent along the coasts of Oregon and Washington where my geologist father pursued his field studies. My interest in marine science was kindled in 1969 by my dad's underwater exploits during Tektite I and II: 60 and 20 day missions, living in a habitat on the Caribbean sea floor. Following in my father's flippers, I began SCUBA diving at age 15, exploring the rocky reefs and kelp forests of Monterey Bay. In addition to diving, I spent large amounts of time as a teen exploring California's coastal range as an avid backpacker and fisherman. In 1976 I graduated from Homestead High School in Cupertino, CA.

Education

Believing that you can never be too close to the ocean, I attended the University of California at San Diego as an undergraduate, where I majored in scuba diving, intramural sports, and... oh yeah... Biology. After that, I joined Bob Warner's Lab at the University of California at Santa Barbara, recieving a PhD in 1987 for my field studies of territorial behavior by coral reef fish in Panama. I then took a break from the ocean to conduct several years of post-doctoral field work on gazelles in Kenya with Jack Bradbury and Sandy Vehrencamp, and my newlywed wife, Lisa (also a biologist). I returned to marine studies in 1992 as a postdoctoral fellow at the Smithsonian Tropical Research Institute in Panama, There, I lived on a small island with my wife and two children for almost five years. Before moving to Portland in 1998 I spent a year lecturing and writing at the University of California at Santa Cruz. Since being hired at Lewis and Clark College, I have enjoyed sabbatical leaves at the University of Guam and James Cook University in Townsville, Australia. I have led biology-focused overseas programs with Lewis and Clark College to Micronesia and East Africa (twice).
