Sarah Cornell is the research coordinator of the Planetary Boundaries research group at the SRC, and a co-convenor of the international Planetary Boundaries Research Network. Both of these initiatives take a transdisciplinary approach and link insights from Earth system science and social-ecological resilience, to better characterise the complex issues of global sustainability. Sarah’s research background is in marine and atmospheric biogeochemistry, but like many global change scientists, she has a very interdisciplinary research trajectory. She has worked on integrated environmental assessment, risk management, sustainability governance, and the philosophy of science. Her current research focuses on conceptualisations of humans in the Earth system. Her main interests are in obtaining a multidimensional understanding of anthropogenic global changes and what they mean for people.
