Monday, October 13th, 2014 - Dr. Sean Gulick uses sub-seafloor imaging tools to understand Earth history

13Oct

Dr. Sean Gulick, a research professor at the University of Texas Institute for Geophysics, sat down with us to talk about his research that deals with plate tectonics and its interaction with various systems such as erosion from mountains, glaciers and regional climate. The main tools that Dr. Gulick uses is 2D and 3D seismic imaging of the sediments and rocks beneath the seafloor to study the imprint of plate tectonics and the mechanisms through which it is manifest. Dr. Gulick went into detail about some of his recent projects offshore Antarctica and Alaska, and also talked about his work mapping the K-Pg impact crater. This crater, located in the Yucatan Peninsula, was caused by the asteroid that was responsible for the extinction of dinosaurs. Listen to this episode to hear Dr. Gulick talk about geology, geophysics, tectonics and day-to-day life as a seagoing researcher!

Monday, October 6th, 2014 - Kelly Pierce gives us a glimpse into the fascinating life of ticks and the pathogens they can carry

6Oct

On this episode, University of Texas at Austin Integrative Biology student, Kelly Pierce gives us a glimpse into the fascinating life and behavior of ticks. She talks about tick-borne diseases such as Lyme's disease, Rocky Mountain Spotted fever, and how these diseases are transmitted, and what motivates ticks in choosing their hosts. Kelly's research has taken her out to the field in east Texas where she has collected tick-related data from raccoons, possums, and deer. Tune in to this episode to hear from Kelly about some of the methods, motivations, goals, and results from tick-related research and the intricacies of tick-borne disease transmission.
