As a broadly trained agroecologist, Jennifer Blesh, PhD, uses interdisciplinary research approaches to understand how different agrifood systems impact ecological and social processes. Her ecological research focuses on soil nitrogen and carbon biogeochemical cycles, agroecosystem nutrient management, and legume nitrogen fixation. Blesh’s research program pays particular attention to alternative production-consumption relations, and is guided by a pragmatic motivation to support development of more ecologically sustainable and equitable food systems. Previous to her position at SEAS, Blesh served as a post-doctoral fellow with the National Science Foundation International Research Fellowship Program at the Federal University of Mato Grosso in Brazil. Current projects include assessing the socioecological resilience of family farms in Brazil, and research in the U.S. centered on cropping system diversification through winter cover crops and improving nitrogen retention in farm fields.
