Jason McLachlan is an Associate Professor in the University of Notre Dame's Department of Biological Sciences. He studies the resilience of terrestrial and coastal ecosystems to the impact of climate change and land use.

He has published scholarly articles on the pace and magnitude of environmental change in Global Change Biology, Ecology, Nature, and elsewhere. He also writes about the significance of environmental change on management and policy in The Proceedings of the National Academy of Sciences, Issues in Science & Technology, Conservation Biology, and elsewhere.

McLachlan leads the PalEON project, aimed at improving long-term forecasts of ecosystems by constraining the models we use to predict ecosystem change with empirical data at long time scales. He is a founding member of the grass-roots Ecological Forecasting Initiative, where he leads the education working-group, whose goal is to ensure that the quantitative tools used for environmental forecasts are available to the breadth of students, instructors, and managers who need them.
