The Department of Aerospace and Ocean Engineering offers a unique blend of two disciplines that takes advantage of commonality in the analysis and design of aerospace and ocean systems. Undergraduate and graduate degrees are offered in both disciplines, with more than 570 undergraduate students and more than 125 graduate students enrolled. We have a yearly graduation rate of some 100 Bachelor's, 25 Master's and 10 Doctoral degrees. The Department has 21 full-time faculty working in aerodynamics, hydrodynamics, structural mechanics, material science, dynamics and control, multidisciplinary design optimization, and energy systems. All faculty are actively engaged in our broad research program, which has annual expenditures of more than $6.5 million, and all teach at the undergraduate and graduate levels. The Department has extensive facilities including world class wind-tunnels, water tunnels, structural test equipment, high-performance computer systems, and state-of-the-art spacecraft simulators.
