My long-term research goal is to develop predictive surface process models, which form a tool to quantify responses of the Earth system to changing environmental conditions.
I have a keen interest in using field studies to critically assess model performance. I have special interest and concern for remote and pristine regions of the world. The fact that global changes are amplified in high latitudes stresses the importance of working in these regions for a global understanding of the changing environment.
Current research projects involve sedimentary processes in fjord environments, and floodplain sedimentation. I have interest in Greenlandic rivers and their response to Greenland Ice Sheet melt, and in Arctic coastal erosion mostly applied to the Beaufort Sea coast.
Additionally, I am the Deputy Director of the Community Surface Dynamics Modeling System (CSDMS), where our team promotes the modeling of surface processes by developing, supporting, and disseminating integrated software modules that predict fluxes of water, sediment and nutrients in landscapes and their sedimentary basins. I am most involved in the ‘Coastal’ and ‘Education and Knowledge Transfer’ Working Groups.

I have always greatly enjoyed sharing my enthusiasm for the Earth Sciences. As a teacher I want to inspire, provide opportunities and empower. I see science as a process that highlights questioning, discovery, challenge, and synthesis towards solution. For me, science and engineering is all about investigating the world around oneself, and drawing conclusions based on a combination of collected data, hypotheses, and thorough analysis. If that can happen in the field, all for the better! I strive to pass along an exciting view of science, as well as a firm footing in methodologies and quantitative reasoning.
I am always interested in engaging with students who are looking into graduate research. Work in my growing group of sedimentary process modelers investigates sediment fluxes from Greenland, river and delta permafrost dynamics in Alaska and sedimentation rates in the Ganges delta in Bangladesh. These projects provide opportunities for new exciting new sedimentology and river/delta science topics, with a combination of fieldwork and modeling.
