This semester the Office of Admissions welcomed three new Program Assistants (PAs) to the team. This week I'm introducing you to each of them in the form of self-interviews. Next up, Andrew Liu. He's studying International Security Policy, worked in the Pentagon's Office of the Secretary of Defense as a security policy intern last summer, and served as an active duty Marine for about seven years. Here's what he has to say about his time and SIPA.
