Jing Liu (GLASSNET Science Coordinator)
Jing Liu is a Research Economist in the Department of Agricultural Economics at Purdue University, serves as Science Coordinator of the GLASSNET project, and leads the SIMPLE-G Short Course. Her research focuses on the interactions of agricultural activities and water resources, in which she uses quantitative equilibrium and statistical models to evaluate the economic impacts of changing water quantity and quality on food security and environments at both global and local scales. Her current projects investigate the effectiveness of different conservation practices to manage nitrate leaching in the US, as well as the interplay of carbon policy and agricultural conservation policies. Jing is a major contributor of variant versions of the SIMPLE-G models, leads NSF-funded projects to develop SIMPLE-G-China and SIMPLE-G-Brazil, and applies these tools to study the food-energy-water nexus. Jing also works closely with the Center for Global Trade Analysis at Purdue University, which coordinates the Global Trade Analysis Project (GTAP).
Justin Andrew Johnson
Justin is an Assistant Professor of Applied Economics at the University of Minnesota. He received his Ph.D. in 2014 from Applied Economics at the University of Minnesota and his B.A. in economics from St. Olaf College. Justin works closely with the Natural Capital Project at The Institute on the Environment, University of Minnesota and Stanford University. Justin’s research focuses on how the economy affects the environment, and vice versa, on global to local scales. Currently, Justin leads a project that links the Global Trade Analysis Project (GTAP) out of Purdue University with the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model from the Natural Capital Project, aiming to build strong quantitative evidence on how changes in ecosystem services affect economic performance at the macroeconomic level and how global policies can be designed to sustainably manage our natural capital. In his spare time, Justin is an avid board game designer.
Iman is a post-doctoral research associate at Center for Global Trade Analysis at Purdue University. He conducts policy-relevant research on the interaction of social and environmental systems addressing major sustainability and resilience challenges regarding international agricultural trade, land use, water resources, and climate change. He studies food security and environmental sustainability employing cutting-edge methods in coupling natural-human systems. The strength of his research is a global-to-local-to-global approach that considers economic feedbacks and local conditions. Recently, he coupled a global Water Balance Model with a global land-use model and a partial equilibrium trade model to establish an advanced framework in which he explores the consequences of a pandemic like COVID-19 co-occurring with heat and water stress.
Danielle is a Research Assistant Professor in the Earth Systems Research Center at the University of New Hampshire. Her work focuses on the role of water resources in global food security, and the complex systems dynamics that develop within agricultural water networks. Dr. Grogan also studies the role of winter and cold region climate change in shifting hydrologic regimes, and the intersection of climate and policy in water resource management. Hydrologic modeling and the development of interdisciplinary model systems forms the basis of Dr. Grogan’s research methods. She is a Co-PI for GLASSNET and a member of the Leadership Team.
