Gaylon S. Campbell
Dr. Gaylon S. Campbell has been a research scientist and engineer at Decagon for 12 years following nearly 30 years on faculty at Washington State University. Dr. Campbell's first experience with environmental measurement came in the lab of Sterling Taylor at Utah State University making water potential measurements to understand plant water status. Since then, because of a love of electronics and understanding how things work, Dr. Campbell has become one of the world's foremost authorities on physical measurements in the soil-plant-atmosphere continuum. Among his long list of publications, his book written with Dr. John Norman on Environmental Biophysics provides a critical foundation for anyone interested in understanding the physics of the natural world.
Colin S. Campbell
Dr. Colin S. Campbell has been a research scientist at Decagon for 11 years following his Ph.D. at Texas A&M University and is currently serving as Vice President of Research and Development. He is also adjunct faculty with the Dept. of Crop and Soil Sciences at Washington State University where he co-teaches Environmental Biophysics. Dr. Campbell's early research focused on field-scale measurements of CO2 and water vapor flux but has shifted towards moisture and heat flow instrumentation for the soil-plant-atmosphere continuum.
Doug R. Cobos
Dr. Douglas R. Cobos is a Research Scientist and the Director of Research and Development at Decagon Devices. He also holds an adjunct appointment in the Department of Crop and Soil Sciences at Washington State University where he co-teaches Environmental Biophysics. Doug's advanced degrees are from Texas A&M and the University of Minnesota in Soil Science. Doug was the Lead Engineer for the Thermal and Electrical Conductivity Probe (TECP) that was designed by Decagon and flew to Mars aboard NASA's 2008 Phoenix Scout Lander. His current research is centered on instrumentation development for soil and plant sciences.
Paolo Castiglione

Dr. Paolo Castiglione is the newest addition to the Decagon R&D team. Paolo came to Decagon from Bozeman, Montana where he was the principal researcher at Soils Sensors Laboratory, where he designed and built TDR sensors, and a research scientist at Montana State University. Dr. Castiglione’s previous research focused on theoretical applications of spectroscopy signals. At Decagon, he’ll be putting his theoretical findings to the test for new soils and foods instrumentation.
