Lara_in_ManausLara Kueppers joined UC Berkeley in 2017 after working as a research scientist at Berkeley Lab and a professor at UC Merced. She likes to move between experimental work in the field and models of the biosphere that represent ecosystem interactions with the atmosphere. She also enjoys collaborating with engineers, economists, and public policy experts to address societally relevant questions related to environmental change.

adamAdam Hanbury-Brown is a PhD student at UC Berkeley studying tree seedling recruitment in tropical forests and Roosevelt elk movements and habitat selection in Northern California.



Jabis-MeredithMeredith Jabis is currently finishing her dissertation studying the impacts of climate change in alpine plant communities.  She worked with Lara on the Alpine Treeline Warming Experiment and focused on the impacts of warming temperatures on alpine plant phenology and the interactions between recruiting tree seedlings and neighboring alpine plants. She is also using the long-term GLORIA (Global Observation Research Initiative in Alpine Environments) project to study the timeframe under which changes in alpine community composition can be observed under a naturally changing climate.


Tom Powell is a postdoc at Berkeley Lab working with NGEE Tropics team to model tropical forest dynamics in response to climate variability and change. More generally, Tom is a Forest ecologist that studies how disturbances, climate change, and land management impact forest ecosystem function and services. He completed his PhD in 2015 at Harvard University.



Dianne Quiroz is a research assistant quantifying rates of nitrogen fixation by bacteria associated with conifer foliage in Western U.S. forests. She was an LBNL SULI/BLUR student after graduating from UC Berkeley in 2015. Dianne is broadly interested in the dynamics of community-level responses to anthropogenic global change and intends to pursue graduate study in ecology.


Hilary Henry is a Masters Student in the Energy and Resources Group. She is interested in connecting science, policy, and community engagement to better protect the ecosystems of the Western United States. Hilary has been working with Tom Powell and Lara Kueppers at the Rocky Mountain Biological Laboratory in Gothic, Colorado to better understand the physiological traits of conifers in alpine environments. Hilary holds a BA in Environmental Science and Policy from Duke University. Prior to returning to graduate school, she worked for the Gunnison Public Lands Initiative on a campaign to protect public lands with Wilderness and Special Management Area designations and as an administrator for the Town of Crested Butte, coordinating their Open Space program.

Yan Bai is a visiting PhD student from Beijing Normal University, China. For the past two years, his research has mainly focused on plant transpiration and plant-water relations in dryland ecosystems in an arid region of China. In 2018-2019, he will learn about and use the FATES vegetation demographic model with Prof. Kueppers at UC Berkeley and collaborators at LBL.
