Mary Kappus

Mary Kappus retired as the Head of the Coastal and Ocean Remote Sensing Branch in NRL’s Remote Sensing Division.  The Branch seeks to advance the science and technologies of remote sensing and apply them to issues of the coastal ocean environment that influence Naval operations.  She has BS degrees in Civil Engineering and Earth/Planetary Science from MIT and a PhD in Earth Science from UCSD.  Her ties to the Navy go back to a Naval ROTC scholarship in college, followed by 6 years of active duty in the Civil Engineer Corps and another 20 years in the Naval Reserves, from which she retired as Captain.  She has worked at NRL in three separate periods, first as a post-doc in 1991, at which time she joined NRLFCU, where she has been a member ever since.  She has been very pleased with the NRLFCU over the years, and wants to help ensure that it stays focused on member service while adapting to the rapidly changing technological and financial landscape. She currently serves on the Governance Committee.
