Swiss Seismological Service, ETH Zurich
Welcome to my website! I am Sin-Mei Wu, a postdoctoral fellow at Swiss Seismological Service (SED) at ETH Zurich. Before joining SED, I participated in the Seismic Imaging Group and the Seismograph Stations at the University of Utah, USA. I am a geophysicist, seismologist, basketball and ski enthusiast. I obtained my Bachelor degree in 2012 from National Central University (Taiwan) and my Master degree in 2014 from National Taiwan University (Taiwan), both are in Geoscience.
My main research interest is exploring nature using seismic interferometry and array data. Through the research projects conducted at the University of Utah, I am fascinated by how much further details we can learn about Geysers and Volcanoes from the advanced data collection and the methodology development, including (but not limited to) ambient noise imaging, seismic source location (polarization + back projection), and coda wave interferometry. Beyond the static characteristics of the systems, I dedicate to the spatiotemporal patterns (4D) to understand the evolution, or the dynamics of the natural systems.
In addition, beyond the shallow Earth, I am also interested in understanding the formation and the evolution of Earth's Inner Core, such as what are the spatial patterns of the core nowadays and how/why the core evolved to the current status. I study these questions primarily via core phases of seismic signals and I look forward to learning more after combining the knowledge beyond Seismology.

The first section summaries the studies on naturally eruptive systems (geysers and volcanoes) using our own nodal data. The interested/studied areas are confined within the top 100 m–1 km of Earth's crust. The second section focuses on deeper, larger scale structure of Earth – inner core. The interested scale length is within 10 km but is situated thousands of kilometers beneath the surface.
