James Rising is an interdisciplinary modeler, studying the feedback between environmental and human systems, and focusing on the impacts of climate change and the water-energy-food nexus.  Dr. Rising draws upon analytical and empirical approaches from multiple fields and develops computational and statistical models to understand integrated global challenges.  Prior to joining the University of Chicago, he was a postdoctoral fellow at the Energy & Resources Group at UC Berkeley after receiving his Ph.D. from Columbia University's program in Sustainable Development.  He previously taught within MIT's Experimental Study Group and at Franklin W. Olin College of Engineering. Until recently, he worked as a software developer, working with over a dozen companies on audio and video processing, social networks, and artificial intelligence.

I currently do research on extreme event characterization, modeling and forecasting using geological data like climate models and observations. For example, are days of extreme temperatures getting more frequent? Or is the annual temperature profile more variable with the current post-industrial climate forcings compared to the pre-industrial era? To answer these questions I look at climate model output, e.g. Global Circulation Models, using different starting conditions and see how their behavior changes statistically.

Related to this is also the desire to incorporate a more statistical framework with the current deterministic climate models. This involves for example adaptive grid sizes and time steps dependent on desired spatio-temporal resolution.

Delphine Deryng

Postdoctoral Scholar, Computation Institute, University of Chicago

Adjunct Research Scientist, NASA Goddard Institute for Space Studies & Columbia University Center for Climate Systems Research


Areas of Expertise:

  • Agricultural systems and climate change
  • Impacts, adaptation and vulnerability
  • The water-energy-food nexus
  • Modeling uncertainty and robust decision making

Delphine Deryng's research deals with global environmental change issues with a particular interest in agricultural systems and implications for food security. She develops and uses process-based crop modeling tools to explore the interaction between climate, crops and land use decision. She conducts multiple research activities as part of the AgMIP Global Gridded Crop Model Intercomparison (GGCMI) initiative exploring the role of extreme weather events on global crop yield and better understanding the effects of rising atmospheric carbon dioxide concentrations on crop water productivity. In addition, she currently leads the first Regional Gridded Crop Modeling Activity (RGCMA) to assess the potential impacts of irrigated crop production on ground water resources in India under climate change using an ensemble of gridded models and regional climate and agricultural datasets.

Prior joining RDCEP, Delphine worked on southern Africa’s hydro-economy and water security as a Research Associate at the Grantham Research Institute on Climate Change and the Environment at the London School of Economics (2014-2015).

Delphine holds a PhD in Environmental Sciences from the University of East Anglia (2014) and a Masters in Geography from McGill University (2009). She joined the Computation Institute in November 2015.
