The Centre for the Study of Existential Risk (CSER) is a research centre at the University of Cambridge, intended to study possible extinction-level threats posed by present or future technology.
 The co-founders of the centre are Huw Price (a philosophy professor at Cambridge), Martin Rees (a cosmologist, astrophysicist, and former President of the Royal Society) and Jaan Tallinn (a computer programmer and co-founder of Skype).
 CSER's advisors include philosopher Peter Singer, computer scientist Stuart J. Russell, statistician David Spiegelhalter, and cosmologists Stephen Hawking and Max Tegmark.
 Their "goal is to steer a small fraction of Cambridge’s great intellectual resources, and of the reputation built on its past and present scientific pre-eminence, to the task of ensuring that our own species has a long-term future."
OpenAI is a non-profit artificial intelligence (AI) research company that aims to promote and develop friendly AI in such a way as to benefit humanity as a whole.
 The organization aims to "freely collaborate" with other institutions and researchers by making its patents and research open to the public.
 The founders (notably Elon Musk and Sam Altman) are motivated in part by concerns about existential risk from artificial general intelligence.
Nick Bostrom ( ; Swedish: "Niklas Boström" , ] ; born 10 March 1973) is a Swedish philosopher at the University of Oxford known for his work on existential risk, the anthropic principle, human enhancement ethics, superintelligence risks, the reversal test, and consequentialism.
 In 2011, he founded the Oxford Martin Programme on the Impacts of Future Technology, and he is currently the founding director of the Future of Humanity Institute at Oxford University.
A global catastrophic risk is a hypothetical future event that has the potential to damage human well-being on a global scale.
 Some events could cripple or destroy modern civilization.
 Any event that could cause human extinction or permanently and drastically curtail humanity's potential is known as an existential risk.
Our Mathematical Universe: My Quest for the Ultimate Nature of Reality is a 2014 nonfiction book by the Swedish-American cosmologist Max Tegmark.
 Written in popular science format, the book interweaves what a "New York Times" reviewer called "an informative survey of exciting recent developments in astrophysics and quantum theory" with Tegmark's mathematical universe hypothesis, which posits that reality is a mathematical structure.
 This mathematical nature of the universe, Tegmark argues, has important consequences for the way researchers should approach many questions of physics.
The Future of Life Institute (FLI) is a volunteer-run research and outreach organization in the Boston area that works to mitigate existential risks facing humanity, particularly existential risk from advanced artificial intelligence (AI).
 Its founders include MIT cosmologist Max Tegmark, Skype co-founder Jaan Tallinn, and its board of advisors includes cosmologist Stephen Hawking and entrepreneur Elon Musk.
Existential risk from artificial general intelligence
Biotechnology risk is a form of existential risk that could come from biological sources, such as genetically engineered biological agents.
 These can come either intentionally (in the form of bioterrorism/biological weapons) or unintentionally (through the accidental release of engineerer viruses).
 A chapter in biotechnology and biosecurity was published in Nick Bostrom's "Global Catastrophic Risks", which covered risks such as viral agents.
 Since then, new technologies like CRISPR and gene drives have been introduced.
Max Erik Tegmark (born Max Shapiro 5 May 1967) is a Swedish-American cosmologist.
 Tegmark is a professor at the Massachusetts Institute of Technology and the scientific director of the Foundational Questions Institute.
 He is also a co-founder of the Future of Life Institute, and has accepted donations from Elon Musk to investigate existential risk from advanced artificial intelligence.
Seth Baum is an American research involved in the field of risk.
 He is the executive director of the Global Catastrophic Risk Institute (GCRI), a think tank focused on existential risk.
[ He is also affiliated with the Blue Marble Space Institute of Science and the Columbia University Center for Research on Environmental Decisions.

Question: The Centre for the Study of Existential Risk is the home of which Swedish-American cosmologist?
