Career
He is from South Africa. He currently (December 2010) teaches geomatics (surveying) at the New Jersey Institute of Technology. Potts is a Post-Doctoral Researcher in Civil and Environmental Engineering and Geodetic Science.
He and von Frese used gravity measurements by National Aeronautics and Space Administration"s GRACE satellites to identify a 200 mile (300 km) wide mass concentration.
This mass anomaly is centered within a larger ring-like structure visible in radar images of the land surface beneath the Antarctic ice cap. This combination led these researchers to speculate that it may be the result of a large impact event.
