Rajan Ghimire, Ph.D. 

Associate Professor & Research Director

NMSU Carbon Management Center 

Dr. Ghimire's research focuses on improving efficiency, profitability, and soil environmental quality in dryland and irrigation cropping systems. The primary area of their work 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. Dr. Ghimire also serves as a research director for the National Center on Carbon Management and Soil Health within the NMSU College of ACES. The center aims to identify, verify, and disseminate cost-effective practices to soil health and carbon management in all major land use types (croplands, rangelands, forests, and urban lands) prevalent in arid and semi-arid regions. 




We are Hiring - Feb 1, 2026 - posted until filled...

Postdoctoral Research Associate – Soil Health and Carbon Management

A Postdoctoral research associate is sought to work on projects evaluating soil health responses to regenerative management practices and agro/ecovoltaic systems across multiple land uses in New Mexico. The candidate will conduct multi-location field experiments and greenhouse and laboratory assessments of soil health and soil carbon/nitrogen dynamics. S/he should be able to design and establish experiments, collect soil and plant samples from on-station and on-farm plots, analyze soil samples for various parameters, run the statistical analysis, and write manuscripts. Knowledge of advanced research and data analysis techniques, including machine learning and artificial intelligence models, for soil health research would be beneficial. The candidate is expected to have excellent oral and written communication skills, as well as the ability to work independently and collaboratively. The candidate must be able to work in a multicultural environment and create an environment that fosters collegiality, diversity, and teamwork; have knowledge of field and greenhouse research and interest in running laboratory equipment; can manage multiple projects at the same time, prioritize tasks, and meet deadlines; and work with a diverse group of people. Interested candidates should send a single PDF file containing the following documents to Dr. Rajan Ghimire (rghimire@nmsu.edu): (i) a cover letter, (ii) a curriculum vitae, and (iii) a list of three references including names, email addresses, and telephone numbers. Review of applications will begin immediately and continue until the position is filled.
