Sunyoung (Sunny) Park(sunnypark@uchicago.edu) |
I am an Assistant Professor of the Department of the Geophysical Sciences at the University of Chicago. As a geophysicist, my ultimate goal is to understand the Earth’s dynamics by examining the source processes and Earth’s structure. My research covers a wide range of topics in seismology, including earthquake rupture, near-surface seismic structure, mantle transition zone, rheological structure from the asthenosphere to the upper mantle, and seismic hazard assessment.

I’m an NSF EAR postdoctoral fellow in Professor Park’s group at the University of Chicago. I received my PhD in Earth and Planetary Sciences and MS in Applied Statistics from Northwestern University. I previously completed an MS in Geosciences at Penn State University. My research focuses on earthquakes — what they tell us about tectonic processes and the seismic hazards they pose. I incorporate various statistical methods to better understand and quantify earthquake behavior. I recently developed a new earthquake recurrence model that can incorporate a fault’s specific earthquake history to produce more accurate earthquake forecasts. I am currently examining the uncertainties of earthquake stress drop estimates, a commonly estimated but poorly understood earthquake parameter that is used in ground motion prediction studies. I’m also passionate about science policy and ensuring that scientists have a voice in the legislative process.

I am a graduate student in Professor Park’s group. My research interest is mainly about using different observations and methods to discuss the structure and properties of the Earth, especially the deep Earth (from MTZ to the inner core). Those consequences can promote our understanding of Earth’s evolutionary history and dynamics. Besides, cryoseismology and planetary seismology are also attractive to me. My current research is related to ground deformation generated by deep earthquakes. I used to be a geophysics undergraduate advised by Professor Chunquan Yu at SUSTech and my previous project focused on upper mantle earthquakes in Tibet. |

I am a graduate student in Professor Park’s group. I received a BS.c degree in Atmospheric Sciences, and my research interested mainly focus on different non-seismic seismic signals, for example signals induced by atmospheric and oceanic disturbance, volcanos and fluvial process. Those signals can help us uncover the complex relationship among lithosphere, atmosphere, and hydrosphere. I am currently co-supervised by Professor Douglas MacAyeal on cryoseismology research project related to interaction between sea ice or marine ice shelf and ocean. I worked with Professor Wu-Cheng Chi at Academia Sinica in Taiwan on seismic ground tilt signals induces by tsunami. |

I am a graduate student in Professor Park’s group. My research interest focuses on the structures and dynamics of the Earth’s interior. My current research examines postseismic deformation of deep earthquakes to study mantle viscosity and rheological structures. During my undergraduate project, I also worked with Professor Zhouhchuan Huang at Nanjing University on inverting D” anisotropy using shear-wave splitting intensity. |

I am a second-year Geophysical Sciences student at the University of Chicago, broadly interested in seismology and geophysics. As an undergraduate research assistant in the Park Group, my current project focuses on investigating the focal mechanisms and source properties of deep earthquakes through the analysis of global sensor data. We hope to contribute to the understanding of deep earthquakes and to assess the implications these events may have on other earth processes. |
