Portrait of Kiona Ogle

Kiona Ogle

Research Interests Dr. Ogle’s research focuses on developing a mechanistic understanding of how plants and ecosystems are affected by environmental variability, including climate change factors. She uses integrative approaches that meld manipulative field experiments, observational studies, diverse data sources, statistical and mathematical modeling, and computational techniques. Dr. Ogle’s research group Read more…

Benjamin Ruddell

Research Interests Dr. Ruddell’s research interests fall broadly in the area of the quantification and management of complex coupled natural-human systems, including regional water and climate systems and ecosystems that are strongly influenced by the human economy and society- such as in cities, energy, and agriculture. He is a specialist Read more…
Portrait of Robert L. Sanford, Jr. (Buck)

Robert L. Sanford, Jr. (Buck)

Research Interests Sanford’s research focuses on the biogeochemistry of alpine, tropical and dryland ecosystems, particularly in managed and fire affected environments. In addition, paleoecology/land use history, or how biogeochemical soil ’signatures’ that human populations/cultures have left on landscapes affect present day ecological processes. Sanford is the 1997 recipient of the Read more…

Portrait of Jamie Brown with hot springs in the background

Jamie Brown

Brown’s research focuses on predicting feedbacks to global change through the production and consumption of the greenhouse gasses CO2, CH4, and N2O by microorganisms across multiple ecosystems. Brown has also participated in research into carbon and nitrogen cycling by microorganisms in geothermal springs through stable isotope probing. Brown hopes to Read more…

Spencer Christensen

Spencer is a post-baccalaureate lab and research associate for the Mack/Walker and Schuur labs. He primarily processes plants (Arizona) and soils (Alaska and Canada) for radiocarbon and CN content to help research on ecosystem ecology, wildfires, and climate change. He also aids the Mack/Walker lab with Bonanza Creek LTER forest Read more…
Portrait of Chris Ebert, visiting researcher in a forest

Chris Ebert

Ebert’s academic background is in analytical chemistry, primarily performing atomic spectroscopy by inductively coupled plasma-mass spectrometry. He has performed isotopic analyses for nuclear science, environmental science, and forensics. This experience has lead him to ECOSS, where he will be expanding radiocarbon’s role in evaluating tundra carbon cycles and climate change. Read more…

Michaela Hayer

Hayer’s interests include the role of microbial communities in structuring plant communities and vice versa. Current Projects Using network analyses to understand how invasion of non-native plants influence microbial community interactions Using quantitative stable isotope probing (qSIP) to investigate microbial responses to environmental perturbation Selected Publications Schwartz, E., M. Hayer, Read more…
