Professor Joe Dufek & Grad Students Josh Mendez and George McDonald Study Titan


Experiments led by Dr. Josef Dufek with EAS graduate students Joshua Mendez Harper and George McDonald, studied the surface of Saturn's largest moon, Titan.  They found when the wind blows hard enough the particles on the moon become electrically charged. Their finds have recently been published in the journal Nature Geoscience.

Dr. Josef Dufek’s research is primarily focused on the application of fluid dynamics to understand mass and energy transfer in geological processes, with particular emphasis on volcanic systems. Most processes in nature involve multiple phases: for instance, ash particles interacting with a turbulent gas carrier phase in an explosive volcanic eruption or bubbles exsolving and interacting with magma in a conduit. One of his research's goals is to delineate how multiphase interactions contribute to the structure and composition of igneous systems, and the role of such interactions in determining the dynamics and deposit architecture of volcanic flows. He received his Ph.D. in Earth and Space Science from the University of Washington in 2006. After his Post Doctoral Fellowship at UC Berkeley, he joined the Georgia Tech faculty in 2008.
