Welcome to Spatial Ecology Lab

We are a research group studying nonlinear spatial systems in nature in the Department of Environmental Science and Policy at the University of California Davis.

We study nonlinear, spatially extended systems to understand how complex spatial organization emerges from simple local interactions, and how emergent spatial structure governs the behavior of ecological systems.

Many of nature’s most remarkable spatial patterns emerge from simple local interactions. We study nonlinear, spatially extended systems to understand how spatial organization emerges and how it influences ecosystem resilience, critical transitions, and responses to environmental change. Although our study systems range from dryland vegetation and Antarctic microbial communities to coral reefs and biogeomorphic landscapes, they are united by common mathematical structures. Our goal is to uncover general principles governing the emergence and consequences of spatial organization across environmental systems.

Our approach. We combine nonlinear dynamical systems, mathematical modeling, physics-informed machine learning, remote sensing, and field observations to develop mechanistic understanding of spatial organization in nature. Learn more about our Research.

We enjoy working with students who are inspired by big questions, mathematical thinking, and mechanistic understanding. If you aspire to do significant work and enjoy forging novel connections across disciplines, we would love to hear from you (more info)!
