Roger D. Aines, PhD

Roger Aines is the Chief Scientist of the Energy Program at Lawrence Livermore National Laboratory. He holds a Bachelor of Arts degree in Chemistry from Carleton College, and Doctor of Philosophy in geochemistry from the California Institute of Technology. 

Roger leads the Carbon Initiative at LLNL, which aims to understand, develop, and implement technologies for the removal of carbon dioxide from the atmosphere, so-called negative emissions technologies. He has been at LLNL since 1984 working on nuclear waste disposal, environmental remediation, application of stochastic methods to inversion and data fusion, management of carbon emissions including separation technology, and monitoring and verification methods for sequestration. With Amy Aines he authored the recently released Championing Science, a book that helps scientists communicate more effectively with decision makers.

Dan Linehan

Much of Dan Linehan’s writing focuses on using multimedia and multiplatform storytelling to make impacts, especially in the areas of climate change, science, and the environment. He is widely published in many forms of writing and has won awards for his work. A longtime freelancer and author of two highly illustrated nonfiction books, Dan has worked for a film studio, a literary journal, a national laboratory, and leading educational publishers. As a writer, he explored Antarctica and the surrounding regions from 2006 to 2007 and lived in Argentina from 2013 to 2014. His latest work The Princess of the Bottom of the World was inspired by these travels. He holds a BS in physics from Stony Brook University and an MS in materials engineering from Purdue University.

Mark Zelinka, PhD

Mark Zelinka is an atmospheric scientist at Lawrence Livermore National Laboratory (LLNL) who researches climate change. He investigates how much global warming we should expect from increasing amounts of greenhouse gases entering the atmosphere. This inevitably leads him to the study of clouds, which have immense leverage on Earth’s energy balance and can act to amplify global warming. He holds a B.S. in Meteorology from Pennsylvania State University and an M.S. and Ph.D. in Atmospheric Sciences from University of Washington. Mark has been a research scientist at LLNL since 2011.

Céline Bonfils, PhD

Céline Bonfils is a climate scientist at Lawrence Livermore National Laboratory. Her overall research goal is to understand the causes of our recent changing climate. To do that, she identifies “fingerprints” of natural factors (sun, volcanoes, natural climate oscillations), and of human influences (greenhouse gases, pollution particles) on global climate, including the water cycle. She holds a Ph.D. in Oceanology, Meteorology and Environment from the University of Paris VI, France, and worked as a post-doctorate researcher at the University of California, Berkeley. Céline has been part of the detection and attribution team at LLNL since 2004.

Philip Cameron-Smith, PhD

Philip Cameron-Smith is an atmospheric scientist who researches the interactions between atmospheric chemistry, the biosphere, and climate.  This includes emissions of dimethyl sulfide gas from ocean plankton that oxidizes in the atmosphere to form aerosols that promote cloud formation. He also tracks carbonyl sulfide gas to monitor the photosynthesis and health of ecosystems.  Philip holds a BSc in Physics and an MSc in Quantum Optics from Auckland University in New Zealand, and a PhD in Planetary Atmospheres from Oxford University in the United Kingdom.
