Quantitative methods for biodiversity conservation where data are limited, uneven, or brand-new

University of Wisconsin–Madison · Bat Conservation International

Research

I am a conservation ecologist who develops the methods, tools, and approaches needed to tackle pressing conservation challenges, especially in the systems and species that would otherwise go understudied.

Methodological Approaches

I leverage a broad suite of methodological approaches to tackle pressing conservation challenges, with a particular focus on developing the methods needed to conduct research in under-studied systems and taxa.

Data Science

I develop methods to integrate biodiversity data from many sources and account for the biases in large, uneven datasets.

Machine Learning & Quantitative Methods

From computer-vision detection to hierarchical and Bayesian models, I build the analytical tools that turn large, noisy ecological data into inference.

Spatial Modeling

Understanding how organisms interact with, and are limited by, their environment is a central question of ecology.

Remote Monitoring & Bioacoustics

I deploy passive acoustic monitoring, bioacoustic detection, and weather-surveillance radar to observe wildlife at scales that traditional field methods cannot reach.

Stable Isotopes & Endogenous Markers

Analyzing endogenous markers like stable isotopes helps scale studies of animal movement from the individual to the population.

Software Development

I develop open-source software to promote accessible, reproducible science.

About

CJ Campbell in the field

I am a quantitative ecologist working at the interface of academic research and conservation practice, with joint appointments at the University of Wisconsin–Madison and Bat Conservation International. At UW–Madison I am a Research Scientist in the Department of Forest and Wildlife Ecology (beginning August 2026); at Bat Conservation International I am a Quantitative Ecologist. I also led the bat bioacoustics and bioinformatics efforts for XPRIZE Rainforest grand prize–winning team Limelight Rainforest.

I earned my PhD at the University of Florida in Hannah Vander Zanden’s Animal Migration and Ecology Lab, as a University of Florida Biodiversity Institute Fellow and UF Graduate School Fellow. My master’s research (with Dave Nelson at the University of Maryland Center for Environmental Science Appalachian Laboratory and Frostburg State University) was supported by a 2016 NSF East Asia and Pacific Summer Institutes (EAPSI) / JSPS Summer Fellowship.

I completed my B.S. at the University of Vermont, working with Joe Roman at the Gund Institute for the Environment, and spent a semester doing fieldwork in Namibia with Round River Conservation Studies. Before graduate school, I worked as an ecological field technician on projects in the fincas of Chiapas (MEX), the rainforests of Puerto Viejo (Costa Rica), the Ozark mountains of Arkansas, and the cave systems of New York.
