• Undergrad and graduate (Ph.D.) research opportunities

  The University of Texas at Austin hosts an exciting and diverse community of researchers at the Jackson School of Geoscience, which includes the UTIG and DGS branches. We are colocated and collaborate with a number of others on campus, including TACC and ICES.

  We are always looking for motivated students with a keen interest and solid background in the Earth sciences, physics, engineering, or computer science. I like to work with students who think and work independently and challenge and extend my expertise and interests.

  Please consider applying for our program should you be interested in pursuing a PhD in my research group, and see the JSG pages for admission procedures.
