Associate Research Scientist in polar sea ice variability, NASA

Alek Petty is an Associate Research Scientist at NASA’s Goddard Space Flight Center (GSFC) and the University of Maryland; specializing in polar sea ice variability. Alek graduated with an M.Sci in Physics from the University of Bristol in 2010, and a PhD in Climate Science from University College London in 2014. His PhD research involved modeling the sea ice and ocean surrounding Antarctica. His postdoctoral studies extended this research approach to include the remote sensing of Arctic and Southern Ocean sea ice across scales. Alek's research approach now involves utilizing a combination of polar remote sensing data and models to improve our understanding of the polar regions and the wider climate system.
