About Me

I have hybrid educational backgrounds in geology and geography (especially in spatial analysis and cartography). Currently, I am a Ph.D. student in the Department of Geoscience at University of Wisconsin-Madison focusing on dinosaur diversity, stratigraphy, and paleoclimate, as well as the spatiotemporal meta-data analysis and software development for geoscience research. My advisors are Dr. Shaun Marcott and Dr. Shanan Peters. My current works are related to Sparrow, Macrostrat, and GeoDeepDive  projects. 



I am developing UI components and data importing functions for the Sparrow, a small and sophisticated data system for geochronology and geochemistry labs. This software has the goal of managing analytical data for indexing and public access. It is designed for flexibility and extensibility, so that it can be tailored to the needs of individual analytical labs that manage a wide variety of data.


Macrostrat & Paleobiology Databases, and Dinosaurs

I am validating the age model of Cretaceous North America in Macrostrat database by conducting spatiotemporal intersections between Macrostrat and PBDB. At the same time I have created state-of-the-art spatiotemporal reconstructions of sedimentary coverage, paleoenvironment, lithology, and dinosaur diversity history of Cretaceous North America. I am also building new geographic polygons in Macrostrat for Cretaceous Western Interior Seaway.

Holocene Temperature

I retrieved temperature proxy data from all over the world and reconstructed global and regional temperature histories since the Last Glacial Maximum. I compare those proxy data to outputs of computer simulations, and locate any discrepancies (where and when) between the proxy and computer climate models. This will help us understand the recent earth temperature change from a spatiotemporal perspective, and learn if the computer simulation is robust or whether the proxy data are biased to a certain season.


FEM Simulation on Folds

I utilized the Finite Element Method (FEM) to simulate elastic models of multi-layer buckling with heterogeneous matrices. The results show that the Biot-Ramberg equation is applicable to this type of model in predicting the dominant wavelength of the buckling layer after deformation. The competence ratio in the original equation could be best replaced by the ratio between the elasticity of the target layer and the averaged elasticity of matrices in the elastic model of the multi-layer buckling system. 


Induced Earthquakes

The number of earthquakes in North-Central Oklahoma has increased significantly since 2009. Many publications have been investigating the relationship between wastewater injection and earthquakes. The series of papers by Zoback group describe clearly the spatial relationship between injection wells and earthquakes. We conducted spatial and geophysical analyses regarding Phi-H values to better understand the porosity distribution of the Arbuckle group and to identify if there was any relationship between porosity distributions and earthquakes.
