The Hoover Institution is proud to welcome the new class of National Security Affairs Fellows (NSAFs) for the 2014-15 academic year. The NSAF program offers representatives of the US military and government agencies the opportunity to conduct independent research on topics relevant to their respective branches of government and to the practice of diplomacy. Admission to the program is based on direct nominations from each governmental branch. Since the program began in 1969, more than 130 people have participated.

Below is a collection of the NSAFs bios.  To learn more about our fellows, check back at the Hoover website over the course of the year where, like with our previous NSAF class, we will be publishing individual features.  You can also learn more about NSAFs from previous years on the NSAF page.
