Alison Appling, PhD

I am an ecosystem ecologist interested in how natural processes and human activities jointly influence our environment. I focus on how these processes interact to generate nutrient patterns across space and time, because such patterns can help us understand ecosystems better and are often directly relevant to human well-being. I specialize in aquatic systems, including streams, lakes, wetlands, and floodplains, and in the consequences of environmental change for water quality in these systems. I am skilled in field and laboratory studies, project management, simulation modeling, statistical analysis, and synthesis of published and unpublished data to answer new questions.

USGS Data Scientist, April 2016 - present:
I'm still (see below) modeling stream metabolism for sites across the continental United States as part of a USGS Powell Center collaboration. I've also joined the Data Science Team in the USGS Office of Water Information and am now physically based at the Arizona Water Science CenterIn addition to research, I now also contribute to our data science team's activities in creating software tools, communicating science through data visualizations, and training colleagues in scientific computing. 

Postdoctoral Fellow, University of Wisconsin and USGS, April 2015 - April 2016:
I'm currently modeling stream metabolism for sites across the continental United States as part of a USGS Powell Center collaboration. My main office is at the USGS Office of Water Information and Center for Integrated Data Analytics (CIDA) in Middleton, WI, and I spend one day a week at the Center for Freshwater Limnology at the University of Wisconsin at Madison. I work most closely with Jordan Read and others at CIDA, Emily Stanley at UW-Madison, Ted Stets at USGS-NRP in Boulder, CO, and Bob Hall at the University of Wyoming at Laramie.

Postdoctoral Associate, University of New Hampshire, June 2013 - April 2015:
I developed an R package to estimate watershed solute fluxes and studied daily cycles in solute concentrations in rivers of the Northeast with Bill McDowell of the University of New Hampshire. (read more)

Postdoctoral Associate, Duke University, May 2012 - May 2013:
I researched the kinetics of nutrient uptake in river ecosystems with Jim Heffernan of the Nicholas School of the Environment at Duke University. (read more)
