格雷琴北 investigates how plants cope with physically challenging conditions.
Dr. 北's research focuses on plant physiological ecology, with an emphasis on the water relations of arid-land plants and plants in the rainforest canopy; she also investigates cellular and subcellular mechanisms of plant water uptake and transport. Her research has been funded by the National Science Foundation and the Smithsonian Institution. She received the Loftsgordon Outstanding Teaching Award in 2008, the 格雷厄姆L. Sterliing Memorial Award for distinguished teaching, 服务, and professional achievement in 2012, and the Linda and Tod White '59 Teaching Prize in 2015.
