Plenary: Monday 19th August 11:45 - 12:45
Mars: Geochemical Cycling on a Once Habitable World
Monday 19th August 11:45 - 12:45 in Auditorium
About the speaker, Bethany Ehlmann:
Bethany Ehlmann is a Professor of Planetary Science at the Division of Geological and Planetary Sciences, California Institute of Technology and a Research Scientist at the Jet Propulsion Laboratory. Her research group develops and applies infrared spectroscopy and other remote sensing methods to understand the evolution of planetary surfaces across the solar system. Much of her research focuses on rover- and orbiter-based data to understand the geologic history of Mars, particularly the mineralogical and chemical record of hydrothermal processes, groundwaters, lake systems, and long-term climate change. Other recent and ongoing projects include orbiter-based studies of water-rock reactions on the asteroid Ceres, development of instruments for future planetary missions, and microimaging spectroscopy of meteorites and mafic and ultramafic deep drill cores from the Oman ophiolite and Hawaii. She received her undergraduate degree at Washington University in St. Louis, master’s degrees from the University of Oxford, Ph.D. at Brown University, and was a Marie Curie Fellow at the Institut d’Astrophysique Spatiale, prior to her position at Caltech.
Plenary: Tuesday 20th August 11:45 - 12:45
Roberta L. Rudnick
Earth's Continental Crust Through Time
Tuesday 20th August 11:45 - 12:45 in Auditorium
About the speaker, Roberta L. Rudnick:
Roberta Rudnick is a professor in the Department of Earth Sciences at the University of California, Santa Barbara. Her research focuses on the origin and evolution of the continents, particularly the lower continental crust and the underlying mantle lithosphere. Emphasis is placed on integration of data from a wide diversity of sources, including petrography, petrology, major and trace element geochemistry, stable and radiogenic isotope geochemistry, and geophysics in order to determine the bulk composition of the crust, the processes that have influenced its composition through time, and why the Earth has continents. Roberta is an elected Fellow of a number of professional societies, including the Geochemical Society and the European Association of Geochemistry, and is a member of the American Academy of Arts and Sciences, the US National Academy of Sciences, and a foreign associate of the Chinese Academy of Sciences.
Plenary: Wednesday 21st August 11:45 - 12:45
New Synthetic Biology Tools to Track Microbial Processes in Soils and Sediments
Wednesday 21st August 11:45 - 12:45 in Auditorium
About the speaker, Caroline Masiello:
Carrie Masiello is a professor of Earth, Environmental and Planetary Sciences at Rice University in Houston, Texas, where she is also jointly appointed in the departments of Biosciences and Chemistry. She is a biogeochemist and geobiologist whose team builds new tools to study carbon and nitrogen cycling in the Earth system. Her group’s research has involved the development of carbon oxidation state and ecosystem oxidative ratio as a new pair of Earth system tracers, and more recently the applications of synthetic biology to biogeochemical questions. A long-term research focus has been the biogeochemical effects of fire, including the fate of charcoal in the environment.
Plenary: Thursday 22nd August 11:45 - 12:45
Ah-Hyung Alissa Park
Towards Sustainable Energy and Environment: Carbon Capture, Utilization and Storage
Thursday 22nd August 11:45 - 12:45 in Auditorium
About the speaker, Ah-Hyung Alissa Park:
A.-H. Alissa Park is the Lenfest Chair in Applied Climate Science of Earth and Environmental Engineering & Chemical Engineering at Columbia University. She is also the Director of the Lenfest Center for Sustainable Energy at the Earth Institute. Her research focuses on sustainable energy conversion pathways with emphasis on Carbon Capture, Utilization and Storage (CCUS). Current efforts include the fundamental studies of chemical and physical interactions of natural and engineered materials with CO2 such as the development of novel nano-scale hybrid materials for combined CO2 capture and conversion and the investigation of carbon mineralization schemes fixing CO2 into solid carbonates. Park group is also working on innovative fuel synthesis pathways using unconventional energy sources such as shale gas and biomass.
Plenary: Friday 23rd August 11:45 - 12:45
The Onset of Plate Tectonics
Friday 23rd August 11:45 - 12:45 in Auditorium
About the speaker, Chris Hawkesworth:
Chris Hawkesworth applies isotopic systems to unravelling how and when the continental crust was generated and the links between geochemistry and tectonics. He has contributed to our understanding of the generation of subduction-related magmas, continental flood basalts, timescales through U-series isotopes, the development of base metal deposits, and environmental changes throughout time. He has used zircons as an archive of the evolution of the continental crust, and investigated how its composition has changed from the Hadean to the present. He is interested in constraining rates of natural processes, and placing regional studies in a global context. Chris is a graduate of Trinity College Dublin, and obtained his D.Phil at Oxford working with Ron Oxburgh in the Tauern Window of the Eastern Alps. He set up an isotope research group at the Open University before moving to Bristol in 2000. He was Deputy Principal at the University of St Andrews from 2009 to 2014, and he has served as President of the EAG and as a Director of the Geochemical Society. Chris is an elected Fellow of a number of societies including the Royal Society and the Royal Society of Edinburgh, and holds Emeritus positions at the Universities of Bristol and St Andrews.
