Josh Willis

Josh Willis is the principal investigator for NASA's Oceans Melting Greenland (OMG) project, a five-year, multi-pronged investigation of the ocean's role in melting Greenland's ice sheet from the edges, driving global sea levels higher. OMG involves measuring the ice and oceans using aircraft, and the shape and depth of the sea floor from aircraft and ships as well. Willis also is the NASA project scientist for the Jason-3 satellite, launched in January 2016 to continue more than 20 years of sea-level monitoring from orbit. Willis also is a member of NASA's Sea Level Rise Team. He is based at NASA's Jet Propulsion Laboratory in Pasadena, California, where he began as a postdoctoral scholar in 2004 and joined the lab as a scientist in 2006.
