Alpha Omega Epsilon (ΑΩΕ) is a social and professional sorority for women in engineering and technical sciences. The sorority was founded by twenty-seven female engineering students at Marquette University on November 13, 1983, and four months later on March 22, 1984, it became a recognized organization on the Marquette University campus. The idea of uniting female engineers and technical scientists of all curricula as Alpha Omega Epsilon has spread to other campuses. As a result, there are currently forty-eight active chapters of the sorority. Alpha Omega Epsilon enjoys a close working relationship with its male counterpart, Sigma Phi Delta (ΣΦΔ).
