She is one of the leading proponents of alternative models to the established deep mantle thermal plume hypothesis. A mantle plume is an upwelling of abnormally hot rock within the Earth's mantle.  This work makes an important contribution to the understanding of volcanic and earthquake areas such as Hawaii, Iceland and the Yellowstone Caldera. The Hawaii hotspot is perhaps the best known volcanic hotspot on Earth, responsible for the Hawaiian Islands in the Pacific Ocean. The Iceland hotspot is a hotspot which is partly responsible for the high volcanic activity which has formed the island of Iceland. The Yellowstone Caldera is the volcanic Caldera in Yellowstone National Park in the United States.
For her work she was awarded the 2005 Price Medal "for investigations of outstanding merit in solid-earth geophysics, oceanography, or planetary sciences" of the Royal Astronomical Society. Price Medal is a medal of the Royal Astronomical Society. It is now awarded every other year for investigations of outstanding merit in solid-earth Geophysics, The Royal Astronomical Society (RAS is a Learned society that began as the Astronomical Society of London in 1820 to support astronomical research  That same year she was also made a Fellow of the Icelandic National Academy of Sciences.
