Rajan Ghimire, Ph.D. 

Associate Professor and Principal Investigator

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 and would like to work with us. More information about our work:

Wooiklee S. Paye, Ph.D. 
Postdoctoral Scholar
Dr. Paye's research explores the potential to improve soil health and resilience through innovative crop and forage production practices, tillage management in drylands, and perennial/pasture cropping. 

Olufemi Adebayo
Ph.D. Studnet
Olufemi Adebayo is interested in soil health and soil-plant water dynamics. His research project evaluates cover crop and compost effects on soil health and soil-plant water dynamics in winter wheat - sorghum - fallow rotation.  

Sundar Sapkota
Ph.D. Student
Sundar is interested in farming systems innovations for improving soil health and agroecosystem resilience. His project evaluates the effects of circular grass buffer strips on soil health and C/N cycling.

Pramod Acharya 
Ph.D. Student
Pramod is working on forage production systems. He investigates soil C cycling and sequestration potential, greenhouse gas emissions, and nitrogen transformation in forage production systems.
