List of engineering branches

Engineering is the discipline, art, and profession that applies scientific theory to design, develop, and analyze technological solutions. In the contemporary era it is generally considered to consist of the major basic branches of chemical engineering, civil engineering, electrical engineering and mechanical engineering.[1] There are numerous other engineering subdisciplines and interdisciplinary subjects that are derived from concentrations, combinations, or extensions of the major engineering branches.

Chemical Engineering

Chemical Engineering is the application of physical and biological sciences to the process of converting raw materials or chemicals into more useful or valuable forms.

Subdiscipline Scope Major specialties

Materials engineering Involves properties of matter (material) and its applications to engineering
Molecular engineering Focuses on the manufacturing of molecules.
Process engineering Focuses on the design, operation, control, and optimization of chemical processes

  • Plastics engineering, the design of the production process of plastics products
  • Paper engineering, the design of the production process of paper products
  • Textile engineering, Textile engineering courses deal with the application of scientific and engineering principles to the design and control of all aspects of fiber, textile, and apparel processes, products, and machinery. These include natural and man-made materials, interaction of materials with machines, safety and health, energy conservation, and waste and pollution control. Additionally, students are given experience in plant design and layout, machine and wet process design and improvement, and designing and creating textile products. Throughout the textile engineering curriculum, students take classes from other engineering and disciplines including: mechanical, chemical, materials and industrial engineering.

  • River engineering is the process of planned human intervention in the course, characteristics, or flow of a river with the intention of producing some defined benefit—to manage the water resources, to protect against flooding, or to make passage along or across rivers easier.
  • Coastal engineering, the study of the processes ongoing at the shoreline and construction within the coastal zone, often directed at combating erosion of coasts or providing navigational access.
  • Groundwater engineering involves the analysis, monitoring and often modelling of groundwater source to better understand how much remains and if the water can be used for e.g. recharging reservoirs and irrigation.

Electrical engineering

Electrical engineering comprises the study and application of electricity, electronics, and electromagnetism.

Subdiscipline Scope Major specialties
Computer engineering The design and control of computing devices with the application of electrical systems.
  • Software engineering: the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software, and the study of these approaches; that is, the application of engineering and computer science to software.
  • Hardware engineering: designing, developing, and testing various computer equipment. Can range from circuit boards and microprocessors to routers.
  • Network engineering: designing, deploying and maintaining computer networks, such as corporate networks or the Internet.
Electronic engineering The design of circuits that use the electromagnetic properties of electrical components such as resistors, capacitors, inductors, diodes and transistors to achieve a particular functionality.
Optical engineering The design of instruments and systems that utilize the properties of electromagnetic radiation.
Power engineering The generation, transmission and distribution of electricity, and the design of devices such as transformers, electric generators, electric motors, high-voltage engineering, and power electronics.

Mechanical engineering

Mechanical engineering comprises the design, analysis and usage of heat and mechanical power for the operation of machines and mechanical systems.

Systems engineering

Systems engineering is an interdisciplinary field of engineering that focuses on how to design and manage complex engineering projects over their life cycles. Issues such as reliability, logistics, coordination of different teams (requirements management), evaluation measurements, and other disciplines become more difficult when dealing with large or complex projects. Systems engineering deals with work-processes, optimization methods, and risk management tools in such projects. It overlaps technical and human-centered disciplines such as control engineering, industrial engineering, organizational studies, and project management. Systems engineering ensures that all likely aspects of a project or system are considered, and integrated into a whole.


Discipline Scope Major specialties
Aerospace engineering The application of engineering principles to aerospace systems such as aircraft, spacecraft, and ground control systems. Formerly known as aeronautical engineering, concerns the design, construction, and science of both air and space vehicles, primarily on the systems level. Further concerned with the science of force and physics that are particular only to performance in Earth's atmosphere and the expanse of space. Often placed within Vehicle engineering

Applied engineering The field concerned with the application of management, design, and technical skills for the design and integration of systems, the execution of new product designs, the improvement of manufacturing processes, and the management and direction of physical and/or technical functions of a firm or organization. Applied engineering degreed programs typically include instruction in basic engineering principles, project management, industrial processes, systems integration and control, quality control, and statistics.[2]
