In recognition of her distinguished and continued achievement in research, co-founder and director of the Urban Resilience to Extremes Sustainability Research Network (UREx SRN), Nancy Grimm was elected to the National Academy of Sciences in 2019, and will be inducted into the Academy in April 2020. This mark of excellence in science is considered one of the highest honors that a scientist can receive. This fall, she also was honored by Arizona State University, being named Regents Professor. Grimm’s research interests include the interaction of climate variation and change, human activities, and ecosystems. Her long-term stream research focuses on how variability in the hydrologic regime affects the structure and processes of desert streams, especially wetland plant distribution, metabolism, nitrogen cycling, and hyporheic processes. Her related research in cities addresses how stormwater infrastructure affects water and material movement across an urban landscape. As the founding director of the interdisciplinary Central Arizona-Phoenix LTER program, she brought together earth, life, and social scientists to develop new frameworks for understanding urban social-ecological-technological systems (SETS). For UREx SRN, the SETS framing is central. Congratulations to Nancy!
