Key Facts & Information

Overview What makes it possible to create high-technology objects like computers and sports gear? It's the materials inside those products. Materials scientists and engineers develop materials, like metals, ceramics, polymers, and composites, that other engineers need for their designs. Materials scientists and engineers think atomically (meaning they understand things at the nanoscale level), but they design microscopically (at the level of a microscope), and their materials are used macroscopically (at the level the eye can see). From heat shields in space, prosthetic limbs, semiconductors, and sunscreens to snowboards, race cars, hard drives, and baking dishes, materials scientists and engineers make the materials that make life better.

Training, Other Qualifications

A bachelor's degree in physics, chemistry, materials science, or materials engineering, or a related discipline is the minimum educational requirement; however, many research jobs require a master's degree or, more often, a PhD.

Education and Training

Many colleges and universities offer degree programs in chemistry, physics, and engineering. The number of colleges that offer a degree program in materials science and engineering is small, but is gradually increasing.

Students planning careers as materials scientists or engineers should take courses in science and mathematics on their way toward earning a bachelor's degree, should like working with their hands, building scientific apparatus, and performing laboratory experiments, and should like computer modeling.

In addition to taking required courses in analytical, inorganic, organic, and physical chemistry, undergraduate chemistry majors usually study biological sciences, mathematics, physics, and increasingly, computer science. Computer courses are essential because employers prefer job applicants who are able to apply computer skills to modeling and simulation tasks and operate computerized laboratory equipment. This is increasingly important as combinatorial chemistry and advanced screening techniques are more widely applied. Courses in statistics are useful because materials scientists end engineers need the ability to apply basic statistical techniques.

Other Qualifications

Because research and development (R&D) materials scientists are increasingly expected to work on interdisciplinary teams, some understanding of other disciplines, including business and marketing, or economics, is desirable, along with leadership ability and good oral and written communication skills.

Experience, either in academic laboratories or through internships, fellowships, or work-study programs in industry, is also useful. Some employers of materials scientists or engineers, particularly in the pharmaceutical industry, prefer to hire individuals with several years of postdoctoral experience.

Perseverance, curiosity, and the ability to concentrate on detail and to work independently are essential.

Nature of the Work

Everything in the environment, whether naturally occurring or of human design, is composed of chemicals. Materials scientists apply chemistry, as well as physics, to study all aspects of materials. Chemistry, however, plays an increasingly dominant role in materials science because it provides information about the structure and composition of materials.

Materials scientists study the structures and chemical properties of various materials to develop new products or to enhance existing ones. They also determine ways to strengthen or combine materials, or to develop new materials for use in a variety of products. Materials science encompasses the natural and synthetic materials used in a wide range of products and structures—from airplanes, cars, and bridges to clothing and household goods. Materials scientists often specialize in specific areas, such as ceramics or metals.

Materials engineers are involved in the development, processing, and testing of the materials used to create a range of products, from computer chips and aircraft wings to golf clubs and snow skis. They work with metals, ceramics, plastics, semiconductors, and composites to create new materials that meet certain mechanical, electrical, and chemical requirements. They are also involved in selecting materials for new applications. Materials engineers have developed the ability to create and then study materials at an atomic level, using advanced processes to replicate the characteristics of materials and their components with computers. Most materials engineers specialize in a particular material. For example, metallurgical engineers specialize in metals such as steel, and ceramic engineers develop ceramic materials and the processes for making them into useful products, such as glassware or fiber optic communication lines.

Work Environment

Materials scientists and engineers usually work regular hours in offices and laboratories. Research and development materials scientists spend much time in laboratories, but also work in offices when they do theoretical research or plan, record, and report on their lab research. Although some laboratories are small, others are large enough to incorporate prototype chemical manufacturing facilities, as well as advanced testing equipment. In addition to working in a laboratory, materials scientists also work with engineers and processing specialists in industrial manufacturing facilities.

Materials scientists and engineers typically work regular hours. A 40-hour work week is usual, but longer hours are not uncommon. Researchers may be required to work odd hours in laboratories or other locations, depending on the nature of their research.
