What Engineers Do

Aerospace engineers conceive, design, develop, test, and supervise the construction of aerospace vehicle systems such as commercial and military aircraft, helicopters and other types of rotorcraft, and space vehicles and satellites, including launch systems.

Bioengineers solve problems in biology and medicine by applying principles of physical sciences and engineering while applying biological principles to create new engineering paradigms, such as biomimetic materials, DNA computing, and neural networking.

Chemical engineers work in the biochemical and petroleum industries, and in areas such as energy, nanotechnology, systems engineering, biotechnology and biomedical engineering, and advanced materials processing, as well as overseeing the chemical process in many industries.

Civil engineers plan, design, construct, and manage a range of physical systems, such as buildings, bridges, dams and tunnels, transportation systems, water and wastewater treatment systems, coastal and ocean engineering facilities, and environmental engineering projects, related to public works and private enterprises.

Computer scientists are concerned with the design, modeling, analysis, and applications of computer-related systems. They work in areas such as computer system architecture, computer networks, distributed computer systems, programming languages and software systems, information and data management, artificial intelligence, computer science theory, computational systems biology and bioinformatics, and computer vision and graphics

Electrical engineers develop circuits, devices, algorithms, and theories that can be used to sense data, analyze data, extrapolate data, communicate data, and take action in response to the data collected.

Materials engineers are concerned with the structure and properties of materials used in modern technology. They build on the foundation of materials science and work to improve the design, fabrication, and optimal selection of engineering materials, and create new materials.

Mechanical engineers apply principles of mechanics, dynamics, and energy transfer to the design, analysis, testing, and manufacture of consumer and  industrial products.  They create machines used in manufacturing, mechanical components of electronics, engines and power-generating equipment, vehicles and their components, artificial components for the human body, and many other products.
