    Tom Neumann is the Chief of NASA Goddard's Cryospheric Sciences Lab. His work at Goddard has focused on ICESat-2, the next-generation laser altimeter scheduled which launched in 2018. Tom now serves as the ICESat-2 Project Scientist, after serving as the Deputy Project Scientist during the development and implementation stages of ICESat-2 from 2008 to 2018. His research includes both theoretical and experimental studies of the chemical, physical, and thermodynamic properties of polar snow and ice. He has been involved extensively in field work on the Greenland and Antarctic ice sheets, leading four expeditions and participating in five others between the two poles. Recent work has involved studies of snow chemistry on the East Antarctic plateau and calibrating ICESat altimetry data using ground-based GPS surveys in Antarctica.

    Tom joined NASA Goddard Space Flight Center in October 2008. Prior to that, he was an assistant professor in the Geology Department at the University of Vermont. He remains an Affiliate Assistant Professor in Earth and Space Sciences at the University of Washington. He earned a B.A. in geophysical science from the University of Chicago, and a Ph.D. in geophysics from the University of Washington.
