Hongyu is a graduate student in geophysics, in the Department of Earth, Atmospheric and Planetary Sciences, as well as in Imaging and Computing Group. Working with Laurent Demanet, she uses machine-learning algorithms to explore (i.e., extrapolate, generate, extract, etc.) seismic waves and to infer the Earth's structures and properties. Meanwhile, she has studied fault weakening and earthquake instability with Matej Pec using rock deformation experiments. Her research interests range from computational to experimental studies of the Earth, including but not limited to machine learning, seismic imaging, seismic interferometry, inverse problems, signal processing, and geomechanics.
