Mechanical engineering comprises a wide range of activities that include researching, designing, developing, manufacturing, managing and controlling engineering systems and their components. Mechanical engineering is the broadest of all the engineering disciplines and provides the widest range of career opportunities. Systems is where everything comes together. Purdue researchers model processes in everything from manufacturing and aerospace, to energy and human-machine interaction. They pioneer new ways to gather diagnostic data on engines, computer networks, buildings, and many other complex systems. Purdue also has a long history in automatic control, studying both theory and application. Expertise in control and feedback leads to better mechatronics, robotics, vehicles, biomedical tools, and more.
