Fred H. Gage is a professor in the Laboratory of Genetics and the past President (2018-2023) of the Salk Institute. He is an adjunct professor at UC San Diego, and emeritus Co-Director of CARTA. Dr. Gage concentrates on the adult central nervous system and unexpected plasticity and adaptability to environmental stimulation that remains throughout the life of all mammals. His work may lead to methods of replacing or enhancing brain and spinal cord tissues lost or damaged due to Neurodegenerative disease or trauma. Gage's lab showed that, contrary to accepted dogma, human beings are capable of growing new nerve cells throughout life. Small populations of immature nerve cells are found in the adult mammalian brain, a process called Neurogenesis. He is working to understand how these cells can be induced to become mature functioning nerve cells in the adult brain and spinal cord. They showed that environmental enrichment and physical exercise can enhance the growth of new brain cells and they are studying the underlying cellular and molecular mechanisms that may be harnessed to repair the aged and damaged brain and spinal cord. He is a member of the National Academy of Science and the Institute of Medicine.

Mark Moffett is a Research Associate at the Smithsonian. During his six years as a visiting scholar at the Department of Human Evolutionary Biology at Harvard, Mark worked on a synthesis on how societies stay together and fall apart, across species and in humans right up to the present day. His most recent book ties biology with modern psychology and anthropology with surprising insights. "The Human Swarm: How Our Societies Arise, Thrive and Fall," has been called “a magisterial work of monumental importance” by Scientific American columnist Michael Shermer, while Kevin Kelly, founder of Wired magazine, tells us to “read this manifesto if you like to have your mind changed.”

One of only a handful of people to earn a PhD under E.O. Wilson, Moffett is a modern-day explorer with more than a little luck on his side, having accidentally sat on the world’s deadliest snake, battled drug lords with dart guns, and scrambled up a tree to escape bull elephants. His research has focused on the structure of rainforest canopies, social complexity in ants, and the evolution of societies generally.

Dr. Michael Purugganan received his B.S. in Chemistry from the University of the Philippines (1985), an M.A. from Columbia University (1986) and a Ph.D. in Botany with a Global Policy minor at the University of Georgia (1993). After obtaining his Ph.D., he did postdoctoral research as an Alfred P. Sloan Molecular Evolution Fellow at the University of California in San Diego, studying the evolution of development (1993-1995). Dr. Purugganan is a leader in the field of evolutionary and ecological genomics and his work focuses on identifying the molecular basis for evolutionary adaptations that occur in nature. Prior to joining the NYU faculty in 2006, he was the William Neal Reynolds Distinguished Professor of Genetics at North Carolina State University, where he also won the Outstanding Faculty Research Award and the Sigma Xi Research Prize. He is the recipient of an Alfred P. Sloan Foundation Young Investigator Award, a Guggenheim Fellowship, is a Kavli Fellow, and in 2005 was elected a Fellow of the American Association for the Advancement of Science.  Dr. Purugganan has served on the editorial boards of the journals Molecular Biology and Evolution, Molecular Ecology, Trends in Plant Science and the Annual Review of Ecology, Evolution and Systematics.

Veerabhadran Ramanathan is a distinguished professor emeritus of Atmospheric and Climate Sciences at the Scripps Institution of Oceanography, UC San Diego. In 1975, he discovered the super greenhouse effect of Chlorofluorocarbons (also known as 'freons' used as refrigerants). Along with R. Madden, he predicted in 1980 that global warming would be detected by 2000. In 1989, he led a NASA study that used satellite instruments to show that clouds had a large global cooling effect. He led an international field experiment with Paul Crutzen in the 1990s that discovered the widespread Atmospheric Brown Clouds (ABCs) over S. Asia, which have devastating health and climate impacts. He developed light-weight remotely piloted aircraft (RPA) to track pollution plumes from S. Asia, E. Asia, and N. America. His most recent discovery is that mitigation of short-lived climate pollutants (black carbon, methane, ozone, and HFCs) will slow down global warming significantly during this century. The United Nations and 30 countries, including the United States, have now adopted this proposal and a new coalition, called the Climate and Clean Air Coalition, is implementing mitigation actions for short-lived climate pollutants. He advised then-Governor Jerry Brown to pass a bill to drastically reduce emissions of short-lived climate pollutants in California. He founded Project Surya, to mitigate black carbon and other climate-warming emissions from solid biomass cooking in S. Asia and Kenya, and is documenting their effects on public health and the environment. At the University of California (UC), he led the most ambitious effort of his career: Bending the Curve: Climate Change Solutions. The Bending the Curve report, written with fifty leading academics at UC, outlines ten interdisciplinary solutions to the climate problem. He followed this with an undergraduate educational protocol, named Bending the Curve: Climate Solutions, to educate a million climate warriors and climate stewards, which is being taught at many campuses in the US and abroad. He was honored in 2021 with the Blue Planet Prize and in 2018 became the Tang laureate for Sustainability Science. In 2014, Foreign Policy Journal included Ramanathan among the top 100 Thought Leaders of the world. In 2013, he was awarded the top environmental prize from the United Nations, the Champion of Earth for Science and Innovation [www.unep.org/champions]. He has won numerous other prestigious awards, including the Tyler Prize, which is the top environment prize given in the US; the Volvo Prize; the Rossby Prize, and the Zayed Prize. He has been elected to the US National Academy of Sciences, American Philosophical Society, the Pontifical Academy by Pope John Paul II, The World Academy of Sciences, and the Indian National Science Academy. In 2011, he was elected to the Royal Swedish Academy of Sciences, which nominates and awards the Nobel Prizes in the science categories. He is now serving in Pope Francis’ Council for the Pontifical Academy of Sciences. At the Vatican, he co-organized a 2014 historic Vatican meeting on “Sustainable Humanity, Sustainable Nature” of social and natural scientists, philosophers, and policymakers. He briefed Pope Francis in person on the highlights of the meeting. He was the science advisor to Pope Francis' Holy See delegation to the Paris climate summit. He is now leading a Pontifical Academy initiative at the Vatican titled: "Resilience of People and Ecosystems under Climate Stress."

Martin Rees is a Fellow of Trinity College and Emeritus Professor of Cosmology and Astrophysics at the University of Cambridge. He holds the honorary title of Astronomer Royal and also Visiting Professor at Imperial College London and at Leicester University.

After studying at the University of Cambridge, he held post-doctoral positions in the UK and the USA, before becoming a professor at Sussex University. In 1973, he became a fellow of King's College and Plumian Professor of Astronomy and Experimental Philosophy at Cambridge (continuing in the latter post until 1991) and served for ten years as director of Cambridge's Institute of Astronomy. From 1992 to 2003 he was a Royal Society Research Professor, and then from 2004 to 2012, Master of Trinity College. In 2005 he was appointed to the House of Lords, and he was President of the Royal Society for the period 2005-10.

Martin is also one of the co-founders of The Cambridge Centre for the Study of Existential Risk (CSER).

Many scientists are concerned that developments in human technology may soon pose new, extinction-level risks to our species as a whole. Such dangers have been suggested from progress in Artificial Intelligence, from developments in biotechnology and artificial life, from nanotechnology, and from possible extreme effects of anthropogenic climate change. The seriousness of these risks is difficult to assess, but that in itself seems a cause for concern, given how much is at stake.

The Centre — a joint initiative between a philosopher, a scientist, and a software entrepreneur — was founded on the conviction that these issues require a great deal more scientific investigation than they presently receive. CSER is a multidisciplinary research centre dedicated to the study and mitigation of risks of this kind.
