Designing Tomorrow's biodiversity dataIncreasingly scientists and global leaders are recognizing the necessity of designing biodiversity observation networks for addressing the ongoing biodiversity crisis. In collaboration with GEO BON, I develop open sources tools for designing new observation networks using best practices and data. In my research I assess the ability of different design algorithms to meet monitoring goals and provide recommendations for specific ecological contexts.

Understanding Biodiversity change through functional traitsUnderstanding how biodiversity is changing is a fundamental question of ecology and conservation. While species-based metrics fail to capture change in many communities, fucntional diversity offers a powerful alternative for measuring change. We reconstructed timeseries of functional diversity using data from the Biotime database and multiple functional trait databases to look at general trends in change through time.

NEON data for Biodiversity researchThe National Ecological Observation Network provides data spanning taxa across the United States and now has a sufficient number of repeated samples to look at trends through time. We create a pipeline for using NEON data for biodiversity research and take a first look at cross-taxa stability patterns.

taxadb: a tool for maintaing taxonomic consistencyDealing with taxonomic inconsistencies is a major hurdle in synthesis work. Our R package taxadb provides fast and consistent access to taxonomic data providers, resolving thousand of names to ID's in seconds.
