Research and Development


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. There he designed and built TDR sensors and was 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.

Dr. Christopher Lund is a research scientist and product manager for Decagon’s new irrigation management instrumentation group. He has more than a decade of experience working with land surface flux measurements, terrestrial water budgets, and soil-vegetation-atmosphere transfer scheme modelling. Prior to joining Decagon, he served as a research scientist on the NASA-CSUMB SIMS (Satellite Irrigation Management Support) Project, a multi-year collaboration between the California Department of Water Resources, NASA, and CSU Monterey Bay providing California growers with a novel irrigation decision support tools. Dr. Lund’s current research focuses on developing cost-effective irrigation management instrumentation for commercial markets.
