Deirdre Griffin LaHue
(she/her)
Associate Professor, Soil Health & Sustainable Soil Management, PI
My research and extension program focuses on the impacts of agricultural practices on soil health, microbial communities, and the functions they provide. Working across Washington’s annual and perennial crops, I like to take a systems approach to understanding dynamics of soil organic matter, biological activity, and nutrients in agriculture to help improve the resilience of cropping systems.
I received my M.S. and Ph.D. in Soils & Biogeochemistry from UC Davis, where I studied the effects of soil amendments and irrigation management on soil carbon and nitrogen dynamics, soil health, and system productivity and profitability. I earned my B.S. at the University of Maryland in Environmental Science and Policy where I developed my love for soils as a member of the UMD Soil Judging Team.
From: Hyattsville, Maryland, right outside of Washington, DC
Personal interest/fun fact: Before getting into soils, I had a previous career as a ballet dancer with The Washington Ballet (in DC) and Pittsburgh Ballet Theatre. I still enjoy taking local ballet classes, as well as hiking and backpacking around Washington’s beautiful sites.

My research explores how biosolids influence soil health properties and overall soil function in dryland cropping systems. My project is in Central Washington, it spans two sites and 26 years (and counting). Some of the current research being conducted is focused on how biosolids contribute to the soil carbon profile in arid dryland systems, how biosolids effect soil health in cover cropped and grazed systems, and whether biosolids can be used as a tool to improve soil health in dryland cropping systems.
I received my BA in liberal arts from St. John’s College in 2016.
From: Maui, Hawaii
Personal interest/fun fact: Before I came to the NWREC I spent several years working on small farms in Maui, Hawaii, which is where my interest in soil science began.

For my PhD I am working with buckwheat in the NWREC Soil Health Lab and with Dr. Kevin Murphy at the Sustainable Seed Systems Lab/Breadlab. My primary research goals are to develop improved varieties of common buckwheat (Fagopyrum esculentum) suitable for the environment of the Pacific Northwest, and to assess the role of buckwheat in liberating and/or mobilizing plant-available phosphorus in soil. I earned my MS in Crop Physiology in 2023 from California State University, Chico. My Master’s thesis explored 13C isotope discrimination and its correlation with water-use efficiency in faba bean (Vicia faba). In addition to my work with faba bean, I’ve also worked with other annual crops, including common bean, peas, cowpea, soybean, and sunflower.
From: Lincoln, California
Personal interest/fun fact: In my spare time, I enjoy gardening, reading, and exercising.

After dipping my toes into agricultural entomology at the University of Minnesota, I was lucky enough to find my way to WSU Whatcom County Extension and Chris Benedict’s research program there. I was excited to find such diverse cropping systems, a world away from my work in the Midwest, and I’ve never looked back. My work with the Soil Health Lab began when I was able to lend a hand to Dr. Griffin Lahue when she arrived at WSU NWREC in 2019. I’ve been excited to spend part of my time working in the program ever since: I assist with and help organize a variety of field and lab tasks across different projects as needed.
