Integrating Mechanistic and Predictive Understanding of Biogeochemical Cycling Across the Continuum of Terrestrial, Aquatic, and Coastal Ecosystems







About Us

Human societies and earth systems are in constant co-evolution, while anthropogenic impacts on the environment can be both intensified and dampened by natural feedback loops. Our collaborative team seeks to establish a baseline understanding of how ecosystems function naturally and predict the influence of disturbances and human activities on hydrological, biogeochemical, and ecological processes on global, regional, and local scales.

Current Projects

*
All Terrestrial-Aquatic Interface Estuaries Technology R&D

COMPASS-FME

The Coastal Observations, Mechanisms, and Predictions Across Systems and Scales - Field Measurements and Experiments project aims to understand how interactions among water, soils, sediments, and plants drive carbon and nutrient fluxes and transformations across the coastal interface

Tree Methane and Trace Gas Cycling

My team explores the mechanisms of a recently discovered phenomenon - emission and/or uptake of methane and other trace gases like nitrous oxide from trees. We use a range of field and laboratory techniques to understand, and ultimately predict the magnitude and drivers of tree trace gas cycling in upland and wetland forests.

Methane Venting from Forearc Faults in the Puget Sound Estuary

This project seeks to quantify how subsurface methane seeps contribute to greenhouse gas emissions from the Puget Sound estuary to the atmosphere.

Marine Carbon Dioxide Removal

This project will deploy a novel ocean alkalinity elevation system to demonstrate its ability to mitigate both global CO2-driven climate change and regional impacts of ocean acidification.

TROCAS

This project seeks to unravel the sequence of processes and sources of terrestrially-derived organic matter that culminate in the immense carbon dioxide outgassing to the atmosphere from tropical rivers worldwide.

Sensor Development

We develop new approaches for deploying sensors in air, water, soil, and plants and test novel technologies for sensing environmental processes.
