The Division of Civil and Mechanical Systems (CMS)

• Engineers practice the art of problem solving to
  serve society, using mathematics and science.
  Engineering is everywhere in our daily lives.
  The CMS activities are most evident in structures
  and machines, and are primarily based on the
  physical sciences, especially mechanics (i.e.,
  statics and dynamics) and the geosciences, and
  mathematics.
• The Mission of CMS is
• to expand the fundamental knowledge underpinning
  for the engineering profession in application to
  mechanical systems and the constructed
  environment, and
• to support the rapid development and deployment
  of research in service to society and to reduce
  risks induced by natural and technological
  hazards.
• CMS annual research program budget is
  approximately 60M
