The PGSL Team

The Polar Geophysical Simulation Lab (PGSL) at Georgia Tech, in close collaboration with our partner Ice-Climate Lab, forms part of a vibrant polar science research community on campus.

About Our Lab

We are a highly interdisciplinary research group integrating people from multiple fields, including Geophysics, Geosciences, Physics, Mechanical Engineering, Electrical and Computer Engingeering and many more...
