". . . the world is mud-luscious . . . [and] puddle wonderful" –ee cummings
My research broadly focuses on the coupled movement of water and elements (e.g., nutrients such as nitrogen and phosphorus) within waterbodies and through landscapes. I currently focus on this research as a postdoctoral research associate with the Critical Zone Collaboration Networks's Big Data Cluster. My aim is to develop a predictive understanding of watershed behavior to understand how disturbances, such as climate and land use changes, impact water resources. In particular, I leverage complex systems tools (e.g., machine learning) with streamflow and water quality data to understand the controls on nutrient transport from landscapes to surface waters at local and continental scales. I was formerly a postdoctoral research associate with Vermont EPSCoR's Basin Resilience to Extreme Events (BREE) project. For my PhD, I studied (mucky) sediment-water interactions in shallow water bodies (i.e., small lakes, ponds, wetlands, and streams) at Michigan State University's Kellogg Biological Station. Until August 2023, you can find me working from UW-Madison's Center for Limnology as an Honorary Fellow.

- I've moved back to Madison, WI! I'll continue to work as a postdoc with the University of Vermont, but from UW-Madison's Center for Limnology as an Honorary Fellow. Extremely grateful to Emily Stanley for hosting me and for my UVM collaborators for helping me make this happen.
- Another product from our WikiProject Limnology & Oceanography work was published in Frontiers in Education: Using Wikipedia Assignments to Teach Critical Thinking and Scientific Writing in STEM Courses.
- Had a really fun time sharing our critical zone research with the Champlain Research Experience for Secondary Teachers (CREST) 2.0 Program at the University of Vermont. Teachers joined us from the Lake Champlain Basin and from the Jackson, Mississippi area!
- Our Critical Zone Collaboration Network Big Data Cluster had our first in-person (!!) All Hands Meeting in Burlington, Vermont. At long last! Great time brainstorming how to make our work more impactful for society at large.
- Had a great time at the 2022 Joint Aquatic Sciences Meeting in Grand Rapids, MI. Presented my work on catchment controls on concentration-discharge patterns across the contiguous US. I also co-led a workshop exploring non-academic careers in aquatic sciences.
- A lot of perseverance is paying off in 2022. Another publication, "Data imputation for multivariate time series sensor data with large gaps of missing data" was just accepted in IEEE Sensors Journal. This collaboration was initiated with computer and data scientists after I gave a seminar at East Carolina University in 2020.

Thankful for my great collaborators that contributed to this work. Press release here.
- Hot off the presses! In a recent Biogeochemistry Letters paper we examined under-ice nitrogen dynamics in two eutrophic lakes in Vermont. We found that ice cover may promote nitrate loss. Our results suggest that winters with shorter ice duration and more thaw events may result in less nitrate depletion and higher peak nitrate concentrations in shallow eutrophic lakes, with potential implications for N cycling and phytoplankton ecology.
- Our recent paper, Ice cover and thaw events influence nitrogen partitioning and concentration in two shallow eutrophic lakes, in Biogeochemistry letters examines N cycling under-ice during two winters and finds that changing winter conditions may affect N cycling with potential implications for aquatic N budgets and phytoplankton ecology.
- Our paper, Hydrology on high: Assessing the effect of a ski resort expansion at the Mount Mansfield paired catchment study in Vermont USA, led by Jamie Shanley, was accepted for publication in Hydrological Processes. I learned a lot about mountain hydrology through this collaboration!
