Rajan Ghimire, Ph.D. 

Associate Professor, Cropping Systems & Soil Health

My research focuses on improving efficiency, profitability, and soil environmental quality in dryland and irrigation cropping systems. The primary area of my research involves soil organic matter dynamics, carbon and nutrient cycling in agroecosystems, greenhouse gas emissions, soil organic matter-microbial community interactions, and their relationships with sustainable crop production and ecosystem services. Contact me if you are interested in these research topics. More information about
