About Me

I am currently an ORISE Postdoctoral Fellow working with the US EPA, Office of Research and Development. My research interests include biogeochemistry, plant ecophysiology and the impacts of pesticides on honeybees. My PhD dissertation work  focused on the ecology of nitrogen-fixing plants and their role in driving forest nitrogen cycling and productivity. 

I am also interested in using geospatial analysis and machine learning techniques to answer broad-scale ecological questions. Ecology is an ideal field for machine learning because ecological processes vary over time and space (often non-linearly), are scale-dependent and are usually determined by interactions between many correlated variables. Machine learning algorithms give us the flexibility to learn these complex model structures from our data while making relatively few assumptions. 

My hobbies include hiking, running, cycling, gardening, disc golf and adventures with my awesome dog Mumpo and my wife Erin.
