Caldeira Lab

Lei Duan (Postdoctoral Research Scientist)

Lei Duan's research topic is about modeling the climate response to external forcing, especially the global scale geoengineering schemes during his PhD. At Carnegie, he will continue working on climate simulations and also helping with the energy modeling work in Ken Caldeira's group. He had a wonderful experience when he was here previously, and feels happy to come back and work with everyone in Carnegie.

Michael Mastrandrea (Director, Near Zero Project)

Michael Mastrandrea is the Director of Near Zero, which provides credible, impartial, and actionable climate and energy research and policy analysis. Previously, he helped lead development of the Intergovernmental Panel on Climate Change Fifth Assessment Report, a global assessment of climate change science and policy options. His work has focused on strategies for reducing climate risks and integrating expert knowledge and quantitative analysis to inform public and private decisions from global to local scales. He has taught at Stanford University as a Lecturer and Assistant Consulting Professor, and received his PhD from Stanford’s Emmett Interdisciplinary Program in Environment and Resources.

Tyler Ruggles (Postdoctoral Research Scientist)

I am a scientist studying low carbon energy transitions. How do we create a low carbon energy system? What could that system look like? What technological breakthroughs are necessary? These are some of the questions which motivate my research.

My current work focuses on studying the interannual variability of renewable energy resources and potential consequences for a highly-renewable grid. I also model the conversion of electric power to liquid fuels or hydrogen to study the benefits these technologies can bring to the grid including increased flexibility.

Before starting on energy systems research, I completed a PhD in particle physics while based at CERN working for the University of Wisconsin-Madison.

Leslie Willoughby (Science Writer)

Leslie's first love was a horned toad that lived in her backyard in Albuquerque. It disappeared over winter, emerged in spring, and showed her that nature changes over time. Throughout childhood, she yearned to share that lizard's world with others.

In college she studied environmental interpretation. Afterward, at the newly created Ohio EPA, she funded programs that regulated scrubbers in coal-fired power plants and improved sewage treatment facilities. Later, as a science teacher, she set the lab tables with a new narrative each morning. Monday’s tale might compare skeletons; Tuesday’s could mimic a lunar eclipse.

When climate change became the biggest nature story, Leslie signed on as a reporter in the Eastern Sierra. While forest fires rage and drought starves California's snowpack and water supply, Leslie heeds the call for epic writing muscle. She works out every day.
