Welcome!

My interests are in the development of sustainable livestock manure management systems, air and water quality control engineering, bio-energy or bio-fuels, and livestock odor emission control technologies. Specific research themes include: solids-liquid separation for nutrient management; manure characterization; aerobic and anaerobic digestions or treatments (with and without cell-immobilization); Nutrients transport in soils; bio-conversion of livestock waste (composting and vermicomposting); natural livestock-wastewater treatment systems; characterization and quantification of odor, gaseous, and particulate emissions from livestock facilities; and modeling of bio-environmental systems.

  • WSU secures more than $1.5 million for specialty crop research

    Oct 2017  | CAHNRS NEWS

    Seven research teams at Washington State University will enhance the competitiveness of Northwest crops by fighting devastating diseases and advancing sustainable agriculture, thanks to more than $1.5 million in Specialty Crop Block Grant funds from the Washington State and the U.S. Departments of Agriculture.

    To support Washington’s $3 billion apple and pear industry, its $734 million potato industry, and other important crops like fresh strawberries, cut peonies and cider apples, WSU crop scientists, engineers, plant pathologists, economists and other specialists will join forces.

    Enhanced nutrients for sustainable farming

    Specialty crop farmers commonly use manure to fertilize their soils. But manure … » More …
