Carl Boettiger

Job Titles:
  • Associate Professor
  • Faculty Advisor & Associate Professor
Carl Boettiger is an Associate Professor in the Department of Environmental Science, Policy and Management at UC Berkeley. Carl works on problems in ecological forecasting and decision making under uncertainty, with applications for global change, conservation and natural resource management. Carl is particularly interested in how we can predict or manage ecological systems that may experience regime shifts: sudden and dramatic changes that challenge both our models and available data. The rapid expansion in both computational power and the available ecological and environmental data enables and requires new mathematical, statistical and computational approaches to these questions. Ecology has much to learn about what are and are not useful from advances in informatics & computer science, just as it has from statistics and mathematics. Traditional approaches to ecological modeling and resource management such as stochastic dynamic systems, Bayesian inference, and optimal control theory must be adapted both to take advantage of all available data while also dealing with its imperfections. Carl's approach blends ecological theory with the synthesis of heterogeneous data and the development of software-- a combination now recognized as data science. Carl is a co-founder of the rOpenSci project, a senior fellow at BIDS, and a science adviser to NCEAS, reflecting his interests in open science, data science, and ecoinformatics.

Paolo D'Odorico

Job Titles:
  • Professor
Paolo D'Odorico is a Professor in the Department of Environmental Science, Policy and Management at UC Berkeley. His research focuses on the role of hydrological processes in the functioning of terrestrial ecosystems. Through the analysis of the soil water balance he has highlighted important nonlinearities in the coupling between soil moisture dynamics and plant water stress, biogeochemical cycling, land-atmosphere interactions, plant community composition, and soil susceptibility to wind erosion. Using field observations and process-based models, Paolo is investigating new mechanisms of desertification and factors contributing to the resilience of the desert margins. His group's work has highlighted the role played by positive feedbacks with the physical environment on the resilience of savannas, dry tropical forests, desert shurblands, freshwater wetlands, mangrove swamps, and seagrass meadows. His work has also shown how environmental noise may increase the complexity of ecosystem dynamics by inducing new states, bifurcations, or pattern formation. Paolo is currently investigating the globalization of water through virtual water trade and international land investments, and its impact on water equity, societal resilience, environmental stewardship, and food security.
