Our Staff

As part of the Admission & Student Affairs Division in the USC Viterbi School of Engineering, our admission staff is a bit different from other admission offices.  While we work on undergraduate admission (recruiting, application review, enrollment), we have a focus on student affairs.  We want to find students who will be successful in our programs and in our community.  Getting to know you is important to us because we will be around you for the next few years – not just the application process.

We are inside the Viterbi School and work closely with engineering faculty and the Dean.  Our job is to work with prospective students (and parents) interested in engineering and computer science majors.  We want to help you better understand this place, get through the application process, and ultimately enroll at the Viterbi School.
