Parque Nacional Bahía de Loreto, Baja California Sur, Mexico — UC Davis Ecogeomorphology Field Course, 2018

I’m a postdoctoral researcher in ecology interested in how patterns of species, systems, and scale can inform conservation. I use molecular tools to study biodiversity, species interactions, and responses to anthropogenic impacts in aquatic habitats. My work on fishes, arthropods, and bats connects foundational concepts in ecology and evolution to explore community responses, food webs, and ecosystem services. The approaches I use include ecological modeling, phylogenetics, Big Data, and non-invasive genetic methods, especially eDNA metabarcoding. I’m a values-driven scientist working to make research more inclusive and data more accessible.
Why habitat matters: An Ecologist’s perspective on proposed changes to the Endangered Species Act
A proposed regulatory change undermines protections for hundreds of species across the US. Here’s my perspective.
Bats provide free pest control for local farms
