Geosciences appoints new faculty, Jessica Irving
Jessica Irving joined the Department of Geosciences on Feb. 1, 2013, as an assistant professor for a term of three and a half years. She first came to Guyot Hall in the fall of 2010 to deliver a lecture on "East versus West: Hemispherical structure in Earth's inner core" hosted by Professor Jeroen Tromp.
Irving's research interests are in seismological studies of the deep Earth, with a focus on developing a better understanding of the structure of the inner core. The core segregated itself from the rest of the planet early in Earth's history and is the source of its magnetic field. The inner core has been growing for hundreds of millions of years at the center of the planet. By studying its seismic properties, the core can provide information about the conditions at the center of the Earth presently and through Earth's history. Irving uses body wave observations and normal mode oscillations to study the properties of the Earth's inner core, in particular the presence of velocity anisotropy. By combining these two techniques, she hopes to better understand both the large and small scale structures in the inner core.
Irving obtained her MSci and Ph.D. from the University of Cambridge, where she had been a research associate since 2009, and a fellow of Murray Edwards College since 2010. Irving will be teaching GEO 203 "Fundamentals of Solid Earth Science" in the fall alongside Prof. John Higgins.
