Bill Anderegg

Bill received his bachelors and Ph.D. from Stanford University and did a NOAA Climate & Global Change Postdoctoral Fellowship at Princeton University. He is an Associate Professor in the School of Biological Sciences at the University of Utah.


Antoine Cabon

Antoine received his PhD in Terrestrial Ecology at the Autonomous University of Barcelona, Spain, in 2020. His research aims to better understand the role of plant ecophysiology, hydraulics and biophysics in forest-climate interactions. He is currently focusing on the relationship between tree carbon assimilation and growth.

Steve Kannenberg

Steve received his PhD from Indiana University in 2018, focusing on the physiological strategies that various tree species use to cope with drought stress. Steve’s research focuses on how drought affects forests, from the scale of individual trees all the way up to the whole ecosystem. To build a holistic understanding of the impacts of drought on forest functioning, he leverages a diverse range of approaches including physiological measurements, tree ring chronologies, and eddy flux towers.

German Vargas

I am a plant ecophysiologist focusing on plant responses to environmental change. I combine methods in plant ecophysiology, Bayesian statistics, ecosystem ecology, and modeling. As a post-doctoral researcher in the Anderegg lab at the University of Utah, my work focuses on developing an ecological forecast framework to predict forest ecosystem responses to drought stress. Working across scales from leaves to ecosystems, I combine data on tissue-level plant physiology with meteorological information to inform mathematical models for predicting plant water status, drought-related xylem damage, and net primary productivity. Before joining the lab, I studied the ecological factors shaping drought tolerance traits in tropical plants and linked these traits to ecosystem-level responses to extreme drought. I enjoy cycling, hiking, camping, cooking, and listening to records during my free time.

Chao Wu

Chao received his PhDs at Tsinghua University and University of Exeter in 2019. His research aims to better understand the interaction and feedback between disturbances, vegetation, and climate. He is currently contributing to the effort to quantify the potential for and risks facing forests as natural climate solutions at both regional and global scales.

Graduate students

Jaycie Fickle

Jaycie received a Bachelors and a Masters from California State University, Bakersfield. She is interested in understanding plant responses to drought through interspecific and intraspecific plant variation. Particularly, she is interested in combining modeling approaches with this plant variability to strengthen predictive power for tree mortality.

Kelly Kerr

Kelly received a Bachelors from UC Davis, and a Masters from Oregon State University. Her research interests revolve around the influence of climate on forest ecosystem dynamics. She is particularly interested in using tree physiology, genetics and modelling to understand and predict tree species’ responses to the environmental stressors brought on by climate change.

Annapurna Post-Leon

Purna received her Bachelor’s from Reed College, where her research focused on exploring factors that affect drought responses of bigcone Douglas-fir in southern California. In the Anderegg Lab, she is interested in further investigating impacts of climate change on forests, focusing specifically on the physiological effects of drought and wildfire on western US tree species.

Nicole Zenes

Nickie received a Bachelors from Princeton University. As an undergraduate, she studied the impacts of natural gas pipeline construction and restoration on water quality and vegetation recovery in Pennsylvania and New Jersey. She is currently interested in the role trees play in regulation of the water cycle and how that could be impact by climate change through changes in drought and species composition of forests.
