David M. Lodge

Professor Francis J. DiSalvo Director Cornell Atkinson Center for Sustainability


My appointment at Cornell University began in May of 2016 where I will serve as the first Francis J. DiSalvo Director of the Atkinson Center for a Sustainable Future. My academic home at Cornell will be in the Department of Ecology and Evolutionary Biology with a joint appointment in the College of Agriculture and Life Sciences and the College of Arts and Sciences. As the founder of the University of Notre Dame Environmental Change Initiative (ND-ECI), where researchers strive to conduct research that matters to society, my goal is to find answers to the most critical environmental questions of our time. Along with collaborators and partner organizations, we focus on the interrelated problems of invasive species, land use, and climate change, and their synergistic impacts on water resources. We seek to provide solutions to minimize the trade-offs between human welfare and environmental health where trade-offs are unavoidable, and discover win-win solutions where they are possible. I have conducted extensive research experience on a wide variety of vectors of invasive species, including ships, boats, canals, and commerce in life food, pets and plants. With numerous collaborators, I have studied Eurasian watermilfoil, rusty crayfish, zebra and quagga mussels, and Asian carp and many other species. My research focuses on ecological forecasting to better inform environmental risk assessment, policy development, and natural resource management.  On numerous occasions I have testified before the U.S. Congress, and has also served as an expert witness in federal court. I served as the first chair of the U.S. government’s national Invasive Species Advisory Committee in 2000-01, led research on freshwater biodiversity as part of the United Nations’ Millennium Ecosystem Assessment in 2000-05, and led an expert subcommittee providing advice to the U.S. Environmental Protection Agency on reducing invasions from the ballast water of ships in 2010-11. I am a member of the scientific advisory boards of NOAA and the International Joint Commission. Collaborations with economists, historians, theologians, and philosophers, and has provided me with extensive experience in partnering with organizations such as The Nature Conservancy to help translate and transfer scientific work to the public policy arena. I served as a Jefferson Science Fellow in the US Department of State in 2014-15, and faculty member at the University of Notre Dame for over 28 years.

Research Focus

Many global environmental changes have very large impacts on biodiversity, on community structure, and on the function of terrestrial and aquatic ecosystems. We combine basic and applied ecological research to contribute to conservation of the world’s fresh waters, with a particular emphasis on the causes, effects, and management of biological invasions. Through field and laboratory experiments as well as short- and long-term natural observations, we explore the complex interactions that occur among plants, invertebrates, fish, and other organisms and how aquatic communities change over time. Members of the Lodge Lab are developing new methods in ecological forecasting risk assessment to help guide policy and management actions aimed at preventing species introductions.  We are also advancing novel technologies such as environmental DNA (eDNA) surveillance to improve the study and management of invaders, imperiled species, and other species of interest. Finally, we collaborate extensively across disciplines to link ecology with other fields such as economics to understand how changes in aquatic systems influence human use and perceptions. Current research in my lab focuses on conservation biology, especially on the overlapping spheres of interest described above, all of which relate to current global changes. My students, postdocs, and I have conducted field work in the inland lakes and streams of northern Indiana/southern Michigan, UNDERC in the upper peninsula of Michigan, the Great Lakes, the coastal plain of North Carolina, Denmark, and Kenya. Current funding comes from NSF, EPA, NOAA Sea Grant, USDA, and the US Department of Education.
