Machu Picchu, Peru (Nov 2007)


As an earthquake seismologist, I am interested in using seismic waves to image the structure of the earth. My current research focuses on imaging the transition between the northern and southern Australian cratons with a deployment of 25 broadband seismic stations along the Stuart & Barkley Highways (BILBY). I am also involved in research that uses different phases to elucidate the nature of the earth's core, and helping with a deployment of 40 short period seismic stations around the Lake Toba area in North Sumatra, Indonesia to investigate subduction zone segmentation.

I am also one of two Conveners for the brand new Master of Natural Hazards program at The ANU brings together expertise from the Research School of Earth Sciences and the Research School of Pacific and Asian Studies. This multi-disciplinary approach is reflected in four core courses: two emphasising scientific aspects, and two the socio-cultural and political dimensions. Students can choose elective courses from a wide range offered in the earth sciences and social sciences. Please see here for more information.

My PhD dissertation involved imaging the seismic structure and dynamics of the upper mantle by focusing on different aspects of volcano seismology and mantle dynamics in the Mariana subduction system: volcano seismology to determine the seismic characteristics surrounding the 2003 Anatahan Island eruprtion (Pozgay et al., 2005), shear wave splitting of local S phases to determine mantle flow orientation and magnitude (Pozgay et al., 2007), and spectral analysis of local P and S phases for the first seismic attenuation tomography images at mantle depths of a slow spreading center (Pozgay et al., 2009).

Please have a look around and send me a note for any reason.
