Dr Jack Wilson is a planetary scientist at the Johns Hopkins Applied Physics Laboratory. He holds bachelor's and master's degrees in physics, with an emphasis on astrophysics, from the University of Cambridge and a PhD in astrophysics from Durham University, in the UK. His work specializes in the application of statistical data processing and image reconstruction techniques to remotely sensed data. Specifically, he has applied these techniques to neutron and gamma ray spectroscopic data to improve their utility in inferring surface and near-subsurface composition of airless bodies. Recently, Jack has used Lunar Prospector Gamma Ray Spectrometer data to investigate lunar silicic volcanism and Mars Odyssey Neutron Spectrometer data to examine the global distribution of water on Mars. Currently, he is using Lunar Prospector Neutron Spectrometer data to look at the global evolution of lunar composition and adapting statistical techniques for use with MESSENGER data.
