Carl Bernacchi is a research plant physiologist with the UISDA Agricultural Research Service and professor at the University of Illinois.  He runs a research group that pursues understanding of the impacts of climate and land-use changes on plants. He received his MS from the Bradley University and his Ph.D. at the University of Illinois. Carl’s research addressed the feedbacks between vegetation and climate in a changing environment using in-field experiments and modeling from leaf- to ecosystem-scales. His work addresses many issues related to global challenges in agricultural production, including rising CO2, rising tropospheric O3, increasing temperatures, drought, and land-use change.  His research encompasses techniques that include gas exchange, micrometeorological measurements, and proximal/remote sensing techniques.
