Role functions


Roberta Rudnick

Roberta Rudnick

Roberta Rudnick is a professor in the Department of Earth Sciences at the University of California, Santa Barbara (as of Jan. 1, 2016). 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. She is a Geochemical Fellow and a Fellow of the American Geophysical Union.

Chelsea Rochman

Chelsea Rochman

Chelsea Rochman is an Assistant Professor at the University of Toronto. She received her PhD in Ecology from the University of California, Davis and was a recipient of the Society for Conservation Biology's David H. Smith Postdoctoral Fellowship. Chelsea has been researching the sources, sinks and ecological implications of plastic debris in marine and freshwater habitats for the past decade. She has published dozens of scientific papers in respected journals and has led international working groups about plastic pollution. In addition to her academic research, Chelsea works hard to translate her science beyond academia. She served as an expert witness, testifying in California about microplastics, and presented her work to the United Nations General Assembly in New York, NY, and at the US State Department in Washington, DC.

Bethany Ehlmann

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.

Chris Hawkesworth

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.
