Chen ResearchThe LEES Lab at the University of Toledo, directed by Dr. Jiquan Chen, is interested in scientific investigations and education on fundamental ecosystem and landscape processes for understanding ecosystem functions and management. Our current studies are focused on the carbon and water cycles of different ecosystems (grassland, desert, forest, cropland, wetlands, freshwater) at multiple spatial and temporal scales, bioenergy systems and resource uses, coupled interactions and feedback between climatic change and human activities, and sustainable management and conservation. Our research projects, spreading mostly across North American and Asian landscapes, are based on sound field experiments and monitoring stations, state-of-the-art equipment and technology, modeling, and remote sensing technology.

The LEES Lab is also the home of UT's CESU Program, the Landscape Ecology Working Group (8.01.02) of the IUFRO, the US-China Carbon Consortium (USCCC), UT's NEON Team, and a book series on "Ecosystem Science and Applications – ESA" for the Higher Education Press (HEP) and De Gruyter. We maintain a high ethical and liberal standard for professional collaborations in research and education.
