Based on the number of Master’s degrees awarded annually, the engineering majors offered at U.S. colleges and universities can be roughly divided into one of four size-based categories:

  1. The “Big Four” Disciplines: Civil, Computer, Electrical, and Mechanical Engineering, which together collectively account for approximately two-thirds (67%) of all engineering Master’s degrees awarded annually.
  2. The “Medium Four” Disciplines: Aerospace, Biomedical, Chemical, and Industrial/Manufacturing Engineering, which collectively account for approximately 20% of all engineering Master’s degrees awarded annually.
  3. The “Smaller Ten” Disciplines: Agricultural, Architectural, Engineering Management, Engineering Physics/Engineering Science, Environmental, General Engineering Studies, Materials, Mining, Nuclear, and Petroleum Engineering, which collectively account for less than 10% of all engineering Master’s degrees awarded annually.
  4. The Specialty Disciplines: A variety of specialty disciplines offered (such as Ocean Engineering) that collectively account for less than 5% of all engineering Master’s degrees awarded annually.

The most popular of these specializations have been described below for your reference:

Electrical Engineering8. Electrical Engineering– The developments of electrical and electronic engineers are everywhere. There are thousands of electrical devices and systems available today that electrical engineers have somehow touched.
Anything you plug into the wall – stereos, computers, microwaves, televisions, power tools, air-conditioners, and major appliances – has been touched by an electrical engineer. Even things you can’t plug into the wall – satellites, cellular phones, and beepers – have been designed, manufactured, or modified by electrical engineers. Electrical engineers also work in areas that generate, transmit, and distribute electrical power to consumers.

 

Environmental Engineering9. Environmental Engineering– Environmental engineering focuses on the development of a sustainable future, preventing pollution, assessing the environmental impact of everything, water distribution systems, recycling methods, sewage treatment plants, and pesticide prevention.
This fast-growing field offers a challenging and satisfying chance to protect the health and safety of people and our environment. These earth-friendly professionals concern themselves with preventing and fixing problems caused by industrialization. They concentrate on delivering better environmental conditions for the public through knowledge, research, a caring attitude, and common sense.

 

Heating, Ventilating, Refrigerating and Air Conditioning Engineering10. Heating, Ventilating, Refrigerating, and Air-Conditioning Engineering– Heating, ventilating, refrigeration, and air-conditioning (HVR&AC) engineers have dramatically improved our lives. HVR&AC engineers develop systems to create and maintain safe and comfortable environments. Airplanes, trains, schools, cars, and computer rooms are only a handful of the environments that depend on HVR&AC engineers.

 

Industrial Engineering11. Industrial Engineering– Industrial engineers figure out how to improve everything. They work with people to help them do things better.
Industrial engineers save employers money by streamlining systems, often making the workplace better for employees too. They improve productivity and quality while saving time and money. Industrial engineers work on all type of businesses. They see the big picture and focus on what makes a system perform efficiently, safely, and effectively to produce the highest quality.

 

Manufacturing Engineering12. Manufacturing Engineering– Just as the mechanical engineer designs parts, the manufacturing engineer designs the processes that make them. Wherever there’s a production process to be designed and managed, you’ll find manufacturing engineers at work.
They work with plant managers, production supervisors, CNC programmers, quality managers, product designers, and R&D staff on issues ranging from evaluating new technology and choosing equipment and suppliers to leading industry-wide standards development to reorganizing a plant into a more efficient production system.
