The Campbell Lecture

The Campbell Lecture was created to help further understanding of environmental soil science.

It is named for Gaylon Campbell, who spent nearly 30 years as a professor of environmental biophysics and soil physics in the WSU’s crop and soil sciences department. He retired from WSU in 1998 to become vice president of engineering at Decagon Devices, a local manufacturer of biophysical research instrumentation.

The lecture was created through gifts from Campbell Scientific, Inc., and Decagon Devices, Inc.
