I have been at APL in the SAA (formerly SIS) group since 2007, developing mission planning and data analysis/visualization software.  Notable highlights are the planning and commanding for the MDIS camera suite on MESSENGER (using SciBox) and developing the power and data allocation model (built with Crucible) for the Dragonfly Concept Study Report.  I am interested in generalizing these types of tools to be easily applied to new missions or concepts.
