  Talk Titles

  • Diagenesis, Sulfur, and Giant Zn Deposits.
  • Pyrite as Ore and Gangue in Hydrothermal Systems: Potential and Pitfalls.


Sarah received a B.A. (mod.) in geology from Trinity College Dublin and a Ph.D. in geochemistry from the Royal School of Mines, Imperial College (University of London). Subsequently, she held postdoctoral positions at the Natural History Museum, London, and the University of Leeds before moving to the University of Alberta to take up a position as an assistant professor in 2001. Since 2016, she has been the W3 professor in mineral resources at the Freie Universität Berlin and leads the Inorganic and Isotope Geochemistry section at GFZ Helmholtz Centre Potsdam.

She was the recipient of the Waldemar Lindgren Award from the Society of Economic Geologists in 2007, as well as the William Harvey Gross Medal (2010) and the H.S. Robinson Lecturer Award (2011–2012) from the Mineral Deposits Division of the Geological Association of Canada. She also received the Young Scientist Award from the Mineralogical Association of Canada in 2010.

Sarah has broad research interests in mineral deposit genesis, hydrothermal fluid flow, and water-rock interaction. Recently, her research has been focused on Cu, Zn, and Au deposits in sedimentary basins, sedimentary geochemistry, diagenesis, and ore-forming processes.


To invite Sarah, please review the calendar below and contact her directly. Please keep in mind, lecturers are working professionals and have busy schedules. They have agreed to keep the calendar up to date, but may not reflect recent activity. Please allow for a seven-day response.

Airfare, meals, and other transportation costs are funded by the SEG. We require the host university/institution to cover hotel accommodation costs for one or two nights, and if possible, pick up and return the lecturer to the airport.
