Curriculum Vitae

Dr. John Couture Lab website

My research has four focal themes: 1) integrating chemical and landscape ecology to advance our understanding of the influence of trophic-level interactions on ecosystem functioning, 2) examining the influence of environmental change on plant and insect ecology, across multiple levels of biological organization, to better understand how ecosystems will function in future environments, 3) advancing the ability of hyperspectral data to characterize plant chemical and metabolic profiles, and 4) utilizing spectroscopy to improve precision agriculture. Work in my lab combines analytical chemistry, hyperspectral and remote sensing technology, field-based measurements, manipulative experiments, statistical modeling, and interdisciplinary collaborations to test basic ecological theory, ultimately providing a better understanding of ecosystem functioning and producing solutions to better manage natural and agricultural resources.
