5:45 p.m. – Networking Reception
6:30 p.m. – Presentation

An extra-terrestrial body impacted the Earth in the region that today is the Yucatán Peninsula (Mexico) 65.5 million years ago, causing worldwide devastation that almost certainly was the principal cause of a mass extinction event famous for ending the age of the dinosaurs.

This presentation will describe the working hypothesis for the formation of the Chicxulub and its impact, discuss how researchers test this hypothesis, and explain the goals of an upcoming drilling expedition to the crater in the next couple of years. Learn how geophysicists use modern computing to investigate the deep history of the Earth.


Dr. Gulick is a research associate professor in the Institute for Geophysics at The University of Texas at Austin. His primary scientific interest is the examination of deformation of the Earth. Current projects include examining tectonic and glacial climate linkages in Alaska, investigations of geophysical images of the Chicxulub impact crater, and many others.

Dr. Gulick earned a B.S. from The University of North Carolina and a Ph.D. from Lehigh University.
