Meet the Speakers Pamela Conrad is an astrobiologist and planetary scientist working at the NASA Goddard Space Flight Center in Greenbelt, Maryland. She is deputy principal investigator for the Sample Analysis at Mars (SAM) suite on NASA’s Mars Science Laboratory Curiosity Rover. She is also co-investigator to two different payload investigations on NASA’s Mars 2020 mission. Her current research focus is on understanding planetary habitability and on the development of approaches for its measurement in environments on Earth and on other planets, especially Mars. Cheryl Desha is a Senior Lecturer in Sustainable Development and Discipline Leader for Environmental Sciences within QUT’s Science and Engineering Faculty. Her research focuses on methods and technologies for developing transformational solutions for thriving, resilient and liveable cities. This includes exploring nature’s potential to vacuum particulate matter from the air, air-condition buildings, streets and neighbourhoods, fight mosquito-borne diseases, filter our storm water runoff and improve our ability to recover from illness. Charles Lineweaver is an astrophysicist and associate professor at the Australian National University’s Planetary Science Institute (PSI). His research areas include cosmology, exoplanetology, astrobiology, and cancer. His research has been published in an array of well-regarded scientific publications. Lineweaver was a member of the COBE satellite team that discovered the temperature fluctuations in the cosmic microwave background. Will Steffen is a councillor on the publicly-funded Climate Council of Australia that delivers independent expert information about climate change, and is an emeritus professor at the Australian National University (ANU), Canberra. He is also an adjunct professor at the University of Canberra, working with the Canberra Urban and Regional Futures (CURF) program, and is a member of the ACT Climate Change Council. Previously, Steffen served as executive director of the International Geosphere-Biosphere Programme, based in Stockholm, Sweden, and is currently a senior fellow at the Stockholm Resilience Centre. His research interests span a broad range within the fields of climate and Earth System science, with an emphasis on incorporation of human processes in Earth System modelling and analysis; and on sustainability and climate change, particular in the context of urban areas.
