Rajan Ghimire, Ph.D.
Associate Professor and Research Director
NMSU Carbon Management Center
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
Laboratory Members
Laboratory group, summer 2023
Amrit Dhoj Adhikari, Research Associate Sr
Sundar Sapkota, Postdoctoral Scholar
Dr. Sapkota has expertise in soil carbon sequestration and greenhouse gas emissions. As a postdoctoral scientist, he has been involved in biochar and rangeland soil health projects.
Juan P. Frene, Postdoctoral Scholar
Juan has expertise in soil microbial ecology and microbial regulation of soil C and N cycling. He is evaluating soil health under cover crops and compost and biochar amendments.
Atinderpal Singh, Postdoctoral Scholar
Dr. Atinderpal Singh has expertise in soil health and water dynamics. His research will evaluate soil health dynamics and their relationship with ecosystem functions, specifically soil water conservation in agroecosystems.
Pramod Acharya, Postdoctoral Scholar
Dr. Acharya has expertise in soil health, carbon and nitrogen dynamics, and greenhouse gas emissions. His research involves soil health and carbon management in New Mexico and other water-limited agroecosystems.
Piumi Yaddehi, MS Student
Piumi is interested in greenhouse gas emissions. Her research involves evaluating effects of biochar on soil GHG emissions under field and laboratory conditions.
Dotun Arije, Ph.D. Student
Dotun's research involves evaluating cropping systems and management impacts on soil C sequestration and greenhouse gas emissions using field-based experiments and biogeochemical process-based models.
Barsha will be engaged in soil health assessment in lands facing transition to dryland and soil C sequestration in grasslands chronosequence.
Hamza Badrari, Ph.D. Student
Hamza works on cover crop, compost, and tillage effects on soil health and weed dynamics in semi-arid dryland and limited irrigation cropping systems.
Olufemi Adebayo, Ph.D. Student
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.
