Tong Qiu

Assistant Professor of Ecology

Duke University

I am an ecologist interested in understanding the causes and consequences of biodiversity change at scales ranging from individual organisms to the entire biosphere. I develop data-model synthesis frameworks that integrate remote sensing (e.g., LiDAR, hyperspectral imaging), field sampling, and ecological monitoring networks with Bayesian hierarchical models and Earth System models. I predict how remotely sensed habitats and climate change interact to drive biodiversity shifts, while also quantifying the feedbacks of biodiversity changes on carbon and water exchanges between land and atmosphere. Additionally, I study global forest regeneration potential and its critical role in shaping food web dynamics.

Prior to joining Duke University, I served as a tenure-track assistant professor at the Department of Ecosystem Science and Management at the Pennsylvania State University. I conducted postdoctral research with Dr. Jim Clark and Dr. Jennifer Swenson at the Nicholas School of the Environment. For my doctoral research, I worked with Drs. Conghe Song, Jim Clark, Erika Wise, Diego Riveros-Iregui, and Allen Hurlbert to understand how vegetation phenology is influenced by climate change, extreme weather events, and urbanization.

Xiaolu Li

Xiaolu Li

Postdoc Associate

Duke University

Xiaolu is interested in the interactions between plant phenology, terrestrial ecosystems, and the climate system. She uses a combination of ground observations, remote sensing records, statistical models, and Earth System models to (1) characterize the biodiversity-phenology-climate relationship and how it influences ecosystem functions; (2) quantify the feedbacks of species composition and ecosystem structure change to climate systems; (3) evaluate phenology variability and improve phenology modeling in Earth system models; (4) investigate impacts of phenological shifts on land-atmosphere interactions. She moves to Duke University after completing a one-year postdoc at Penn State in our lab. She worked with Dr. Toby R. Ault for her postdoctoral and dissertation research work.

Undergraduate Researcher

Duke University

Alexis Fox is a freshman at Duke University (Class of 2028). Alexis worked at UVA’s Biocomplexity Institute on research intersecting information theroy and generative AI. As a high school student, Alexis completed a draft that is currently under review for AAAI. The manuscript focused on analyzing current generative model metrics for output quality and proposing a novel metric differentiating inter- and intra-class diversity. She will work on the deep learning project that focused on fusing airborne and terrestrial laser scanning to facilitate the mapping of biodiversity in the eastern forests.
