Architecture and Engineering

Environmental engineers use the principles of engineering, soil science, biology, and chemistry to develop solutions to environmental problems. They work to improve recycling, waste disposal, public health, and water and air pollution control. They also address global issues, such as unsafe drinking water, climate change, and environmental sustainability.

Mechanical engineers research, design, develop, build, and test mechanical and thermal sensors and devices, including tools, engines, and machines.

Health and safety engineers develop procedures and design systems to protect people from illness and injury and property from damage. They combine knowledge of engineering and of health and safety to make sure that chemicals, machinery, software, furniture, and other products will not cause harm to people or damage to property.

Marine engineers and naval architects design, build, and maintain ships, from aircraft carriers to submarines and from sailboats to tankers. Marine engineers are also known as marine design engineers or marine mechanical engineers and are responsible for the internal systems of a ship, such as the propulsion, electrical, refrigeration, and steering systems. Naval architects are responsible for the ship design, including the form, structure, and stability of hulls.

Nuclear engineers research and develop projects or address problems concerning the release, control, and use of nuclear energy and nuclear waste disposal. Some of these engineers research new reactor designs. Others may specialize in the development of safety regulations related to the handling of nuclear materials or operation of nuclear power.

Mining and geological engineers design mines to safely and efficiently remove minerals such as coal and metals for use in manufacturing and utilities.

Petroleum engineers design and develop methods for extracting oil and gas from deposits below the Earth’s surface. Petroleum engineers also find new ways to extract oil and gas from older wells.
