Hi, I'm Aaron.

I'm a data scientist and ecologist.

I live in Durham, NC and work on projects related to water and forests.
You can find me on GitHub and (sometimes) on Twitter...

About me

Professional resume | Academic CV

I am a data scientist interested in water, forests, environmental sensors, and entrepreneurship. As a researcher at Duke University and Colorado State University, I have initiated, collaborated on, and completed scientific projects to measure international greenhouse gas emissions and predict forest responses to climate. My academic work is published in multiple peer-reviewed journals.

Currently I provide analytical and computational support for an international, NSF-funded project to characterize the metabolic pulse of streams.

I have a Ph.D. degree from Duke University, a M.S. degree from Colorado State University, and a B.S. degree from Beloit College. I am interested in applying my analytical skills to help people better manage their relationships with their data and the environment.

I also love restoring my old house in Durham, making maps, climbing, and doing yoga.

What I Do

Statistical modeling and analysis

I create and use Bayesian and machine learning models for prediction and inference. I am experienced with time-series and geospatial analysis.

Data wrangling

I build infrastructure for scientific analysis in R, Python, and Scala. I am experienced at extracting and using data from online portals.

Data management

I create and work with databases (SQL/NoSQL) to efficiently organize and extract data. I have also created web-facing RESTful APIs and online data management dashboards.

Scientific communication

My scientific research is published in peer-revewed journals and highlighted in media outlets. I am excited about interactive visualizations and public presentation.
