Research Interests

I am interested in using seismological data to understand the Earth’s interior. During my undergraduate study at Brown University, I worked with Prof. Karen Fischer on research projects that use shear-wave splitting data to understand mantle deformation. I came to Harvard University for a Master’s in Data Science, with the hope of learning advanced statistical methods that can be applied to solve problems in Earth Sciences. This summer (2020), I am working with Prof. Miaki Ishii on the investigation of the Earth’s inner core boundary structure using PKiKP arrivals (P waves that reflect at the inner-core boundary) at seismic stations around the globe. Initial work involves the calculation of theoretical amplitude ratio between PKiKP and P/ScP arrivals (P/S waves that reflect at the core-mantle boundary) that helps identify PKiKP phases on the seismogram.
