• Undergrad and graduate (Ph.D.) student 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 units with which I am affiliated. At UT, we are colocated and collaborate with a number of others, including at the Texas Advanced Computing Center and the Oden Institute for Computational Engineering and Sciences.

  We are always looking for motivated students with a keen interest and solid background in the Earth sciences, physics, engineering, or computer science. Please take a look at some of our recent publications to give you an idea of current projects, but 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. The (important) Fellowship deadline is December 1 each year. If you think this could be a match, please do reach out by email.
