Welcome to the home page for Dr. Shirley A. Papuga's interdisciplinary research group. Dr. Papugaís research program focuses on the land‐atmosphere exchange of energy, water, and carbon. Land‐atmosphere interactions are a major source of uncertainties in climate change projections, as well as associated mitigation and adaptation strategies. With population and land use projected to increase, an understanding of how both climate change and growth contribute to changes in (1) water, carbon and energy cycling, (2) ecosystem phenology and resilience, and (3) feedbacks to land‐atmosphere interactions are of critical concern to the Papuga Lab.







We are currently looking to hire three undergraduates in our lab for projects related to (1) pecan irrigation use efficiency, (2) transpiration in mixed-conifer ecosystems, and (3) root water-use strategies in shrubland ecosystems. If you are interested in working with us, please contact Dr. Papuga at papuga@email.arizona.edu.
