Research Soil Scientist
USDA-ARS Northwest Agroecosystem Research Unit
Dr. Jeremy Hansen is a USDA-ARS Research Soil Scientist stationed in Pullman Washington. He received a B.Sc from the Utah State University, M.Sc From University of Idaho and Ph.D. from Washington State University in Soil Science. Jeremy has worked for the USDA-ARS for 20 years where he has contributed to numerous projects investigating the soil microbiome and soil health associated with various crops and cropping systems in the dryland regions of the PNW. In his current role, he will be contributing to the efforts of ARS researchers working to quantify and improve soil health of agroecosystems throughout the PNW.
Skills and Expertise
