  • Ph.D., Soil Science, University of Wyoming, Laramie, WY, 2013.
  • M.Sc. Soil Science, Tribhuvan University, Nepal, 2006.
  • B.Sc. Agriculture (Soil Science), Tribhuvan University, Nepal, 2004.

Research Interests

My research focuses on soil and crop management practices that improve efficiency, profitability, and soil environmental quality. I am interested in soil organic carbon and nutrient cycling, soil carbon sequestration, soil-plant relations, and greenhouse gas (CO2, CH4, and N2O) emissions, soil organic matter - microbial community interactions, and their relationships with nutrient cycling and other ecosystem services. I enjoyed working on integrated cropping systems research that emphasizes soil conservation and improve crop yields.
