Advisor: Dr. James Harsh

I come from a small farming community nested in the “hill country” region of central Texas, but completed my undergraduate education in Reno, NV.  At the University of Nevada, I graduated with a B.S. in environmental science, and focused on soil science, environmental chemistry, biofuels synthesis/production, environmental policy and regulations, and community outreach.  After working with indigenous groups impacted by environmental degradation through large-scale mining, in both Nevada and western Africa, I ultimately decided soil science and resource conservation were the logical foundations to center my studies on for my Ph.D.As part of the Low Impact Development research program at WSU, my research will focus on the use of iron-gluconate amended compost and its ability to mitigate the impacts of agricultural land runoff through the adsorption of xenobiotics, excess nutrients, and arsenic, with the main focus being the speciation, fate, and transport of arsenic.

Education Background: B.S. (Environmental Sciences) – University of Nevada, Minor: Analytical Chemistry

Growing up on a farm in rural Minnesota has made a substantial impact on my academic interests. With my life-long experience in agriculture, and the passion for biological sciences I accrued during my undergraduate education, I decided to devote my future studies towards microbiology in agriculture. This led me to a M.S. in Animal Science with an emphasis in ruminant microbiology at South Dakota State University. To broaden my skills and education, I decided to attend WSU starting in the fall of 2017, and focus my doctoral research on rhizosphere microorganisms and their effect on crop productivity. Specifically, I will be working on characterizing metal and micronutrient transformations by the rhizosphere microbiome and phytobiome that enhance plant nutrition and crop yield.

Educational background: M.S. Animal Science (Ruminant Microbiology); B.S. Microbiology, Biotechnology, and Biology; Minors: Chemistry and Psychology – South Dakota State University, Brookings, SD

Advisor: Dr. David Huggins

I was born in a small town in Nanyang, China, a city full of history and beautiful scenery. My passion for plants and nature lead me to higher education regarding natural resources management for both of my Bachelor degree (Northwest A&F University) and my Masters degree (Institute of Soil Science, Chinese Academy of Sciences). What I observed during my courses field trip in 2012, impressed me so much because it is so difficult to find a clear river without pollution caused  in most part by the unsustainable development of the crop lands. I came to WSU to Dr. David Huggins’s Lab in the Fall of 2014 to focus on my research interest of carbon and nitrogen cycling in soil and try to find some practical and meaningful solution for sustainable agriculture development. I like drawing, playing badminton, running and reading, and sometimes I like cooking, but it depends on my mood.

Educational background: B.S. (Northwest A&F University); M.S. (Institute of Soil Science, Chinese Academy of Sciences)

I was brought up in a farming community in Ghana. I enrolled at Kwame Nkrumah University of Sc. and Tech., Kumsi, Ghana in the Department of Crop and Soil Sciences, where I majored in Crop and Soil Sciences. After I graduated, I served as a Teaching and Research Assistant in my department for my National Service. I pursued my M.S. degree in Agronomy at the University of Wyoming. My M.S. research focused on optimizing camelina (Camelina sativa L. Crantz) feedstock production in wheat/fallow rotation in the Great Plains with minimum negative impact on wheat production and the environment. I am currently enrolled at WSU pursuing a Ph.D. in the Soil Science program, under the supervision of Dr. Markus Flury. My research focuses on the use of biodegradable mulch and its impact on agricultural soil ecosystems using pumpkins as a experimental crop at the Puyallup Research & Extension Center.

Educational Background: 2014, M.S. Agronomy, Minor Statistics, Univeristy of Wyoming, Laramie, WY; 2011, B.Sc. Agriculture, Major Crop and Soil Sciences, Kwame Nkrumah University of Sc. and Tech., Kumasi, Ghana

Advisor: Dr. Joan Davenport

Originally from St. Louis, Missouri, Nathan received a B.A. in Communications from Truman State University (2002). After exploring the mountains of Colorado for a few years, he decided to switch gears, get his hands dirty, and pursue an interest in soil science.

He is currently a Ph.D candidate in the Department of Crop and Soil Science and working to “close the loop” at a local military base. He is testing the hypothesis that a waste product (a composted biosolid) can act as an effective nutrient substitute in the soil environment, and therefore be considered a resource.

He enjoys running, hiking, reading, and making beer when not taking soil samples.

Education Background:B.A. (Communication) – Truman State University Att. Turf Management Program – Rutgers State University

I received my BS in Microbiology from BYU and joined Dr. Dave Huggins’ lab in Fall of 2014 as a Master’s Candidate. My research is focused on developing science-based decision support systems for farmers using precision nitrogen management technologies. My interests are in water and soil conservation.

I was born and raised in Minnesota where I grew up loving just about anything to do with the outdoors.  The most influential experiences from my undergrad include the semester I spent in Costa Rica conducting research on an organic cocoa farm. That semester provided the springboard to further research in agricultural systems once back in Minnesota, which transformed into another influential experience as I developed relationships with local farmers and organizations to promote on-farm research trials.I am interested in studying various practices that can make agriculture more sustainable, especially as related to nitrogen management. My research is focused on introducing organic quinoa as an alternative crop for the inland Pacific Northwest. Specifically, I will examine the ecological and economic impacts of incorporating quinoa into organic rotations with other crops common to the region.
