Whenever encompassing dynamics, fluid mechanics, heat and mass transfer, manufacturing and design, nanoelectromechanical and microelectromechanical systems, structural and solid mechanics, and systems and control, The scope of the departmental research and teaching program is broad.

### At the undergraduate level, the department offers accredited programs leading to degrees in Aerospace Engineering and in Mechanical Engineering.

a in Manufacturing Engineering is also offered. On top of this, mechanical Engineering and in Aerospace Engineering. You see, at the graduate level, the department offers programs leading to and Ph. Certainly, further, the department seeks to expand the frontiers of engineering science and to encourage technological innovation while fostering academic excellence and scholarly learning in a collegial environment. After mastering the body of knowledge defined in the major field. Students must be registered throughout the term in which the examination is given and be in good academic standing. Students must was formally admitted to the Ph. The examination must be taken within the first two calendar years from the time of admission into the Ph.
