Postdoctoral Fellow
Greg’s research focuses on the impact cratering process and its effects on planetary surfaces and interiors. He uses numerical methods to simulate the complete evolution of impact basins from transient crater formation through isostatic adjustment, and several additional time-dependent geophysical processes such as lava emplacement and faulting. During his PhD at Purdue University, Greg investigated the mechanics of large impact basin formation (1000s of kilometers in diameter), the influence of thermal contraction on developing positive mass anomalies beneath craters, and the role of impact cratering on creating kilometer-scale topography on Hadean Earth. At UTIG, he is exploring the commonalities between the lunar Schrödinger and Earth’s Chicxulub crater, as well as investigating the effects of Chicxulub’s long-term evolution on its persistent hydrothermal system.
