Existential Risk, Biosecurity And Biotechnology
In the decades to come, advances in biotechnology could bring new risks to both humans and ecosystems. This research focuses on investigating and mitigating the worst possible of these risks, those that could threaten human civilization itself. This interdisciplinary initiative is a collaboration with the Future of Humanity Institute. It utilises a variety of tools ranging from dynamical systems and stochastic processes to case studies and public policy.
Fundamental bounds of existential risk. Although biotechnology will change rapidly (and perhaps unpredictably) over the next century, the underlying fundamentals of ecosystem functioning will remain constant. This line of research attempts to use these fundamentals to constrain the plausible space of existential risks, and refine our search for worst-case scenarios.
Interpreting past catastrophes. A number of biological catastrophes have occurred in the past, including the introduction of European diseases to the Americas, the Black Death, the Permian-Triassic extinction, and the Oxygen Catastrophe. This line of research examines these events and identifies potential ways in which future biotechnologies could trigger similar events.
Anthropics, observation selection effects, and sampling bias. The historical track record of human survival and ecosystem stability could be subject to a special type of sample bias, known as an ‘observation selection effect,’ whereby we only observes data consistent with our own existence. This line of research combines simple models with anthropic principles to investigate existential risk and correct for these sample biases.
Cassidy completed undergraduate studies in Neuroscience and Developmental Biology and a medical degree from the University of Queensland, and holds a Master of Public Health from the University of Melbourne. She has more than five years experience working in hospital and laboratory-based medicine, human biosecurity and communicable disease public health.
Gregory completed a medical degree and an MPhil in Public Health (both from Cambridge) and joins the group after time as a junior doctor and public health trainee. His DPhil, supervised by Mike Bonsall, investigates theoretical properties of Global Catastrophic Biological Risks (GCBRs). He also researches similar topics at the Future of Humanity Institute.
