Disciplines

Research in materials science and engineering may focus on a discipline which could be a specific material or category of material (steel or magnetic materials, for example) or on a theme which could be an approach (such as computational science), a process (such as welding), or a principle common to many materials (corrosion, for example). Below is a list of some of the areas of research currently underway in MIT's DMSE.

Biomaterials

Biomaterials interact with a biological system. Some materials scientists performing biomaterials research are working with medical researchers on implants, stents, or grafts; others are studying how natural materials work in order to mimic their self-assembly or structure.moreabout Biomaterials

Biomolecular Materials

The Biomolecular Materials Group encourages simple organisms to grow and assemble technologically important materials and devices for energy, the environment, and medicine. These hybrid organic-inorganic electronic and magnetic materials have been used in applications as varied as solar cells, batteries, medical diagnostics and basic single molecule interactions related to disease.moreabout Biomolecular Materials

Micro-Electro-Mechanical Systems, orMEMS, are miniaturized mechanical or electro-mechanical devices and structures.moreabout MEMS (Micro-Electro-Mechanical Systems)

DMSE originated as a Department of Metallurgy and Mining, producing graduates whose work in ore refining and steel production led to a great expansion of industry and transportation in the late 19th century. In the modern age, metallurgists are interested in developing new alloys that are stronger, new refining techniques that are less environmentally harmful, and new manufacturing methods.moreabout Metallurgy

This research covers projects ranging from atomic-level manipulation (e.g., nanocrystals) to the micro-scale (e.g., MEMS devices). These new developments promise to enhance our way of life in areas such as communication, healthcare, and transportation, among others.
