Research Mission

To develop system-level noise and vibration solutions based on fundamental and applied research, which will lead to minimal environmental impact.


Many engineering applications require a systems approach to design. For example, in automotive systems, the reduction of noise and vibration is achieved through the combined efforts of modelling of dynamical systems, predicting noise emissions together with designing control systems.

This group endeavors to tackle issues associated with the system as a whole. The typical focus areas include, but not restricted to

  • Design and analysis of mechanisms
  • Vehicle dynamics
  • Rotor dynamics
  • Nonlinear dynamics and chaos
  • Structural health monitoring and prognosis
  • Experimental and analytical vibro-acoustics and aero-acoustics
  • Design of active and passive noise and vibration mitigation systems
  • Machine-Human interface models
  • Design and development of controllers for precision systems
