Wetland landscape flux research:

We research connections between the carbon and water cycles in wetland environments. This field-based research involves long-term measurements of key environmental fluxes (e.g., evapotranspiration, surface water flows, carbon dioxide and methane emissions from the landscape to the atmosphere). This research also provides the basis for process studies and computer modeling approaches to environmental systems.

Research projects will be based in rice fields in Arkansas and low-lying permafrost tundra wetlands in the Arctic. Both projects will use flux budgeting methods to understand the landscape’s ecological and hydrological functioning. This research will connect between site dynamics and climate drivers with the goal of feeding simplified process representations used at the scale of the global climate model. Our rice fields are listed within the AmeriFlux network (Conventional; Alternate Wetting and Drying). Cameras at the site track the greenness phenology and can be viewed here and here.

We have blogged about research at these sites in a series of Field Notes published by the University of Arkansas’s Research Frontiers (One, Two, Three, Four).

Additional flux measurement research

I would also like to develop research threads enhancing the methodology of micrometeorological flux measurements – diving more deeply into the raw 20 Hz data at turbulent structure and coherence, better accounting for the energy imbalance and cospectral attenuation, and reducing the costs of flux measurements.

Spring and snowmelt hydrology

In northern landscapes, the snowmelt period is critical in generating high surface flow and often carries a significant portion of the year’s dissolved carbon fluxes downstream. Following work performed in Russian peatlands and permafrost, I’m interested in examining key landscape contributions to downstream fluxes of dissolved organic matter. I’m particularly interested in working on low-cost methods using UV-Vis spectrophotometry to partition aquatic organic matter into its original source contributions.

Sustainability research

Based on my experiences as a researcher at the University of Hamburg’s “Sustainable Future Postdoc College,” I am interested in developing broad, inter-, multi-, and trans-disciplinary metrics for measuring and evaluating the sustainability of higher education institutions. I’m also interested in expanding upon past research in bringing earth sciences and engineering materials into the (primary through higher education) classroom. Similarly, I believe in generating scientifically-based materials to enhance public understanding of key issues. One example of this kind of outreach is highlighted in an appearance as a Climate Expert on DW’s youtube channel.
