Dr Amal Hajjaj has significant expertise in the design, modelling, and characterization of nonlinear MEMS resonators-based sensors. Her Ph.D. research was focused on theoretically and experimentally investigating the linear and nonlinear dynamics of MEMS resonators when used, mainly, in sensing and filtering applications. In particular, she developed versatile pressure and gas sensor-based MEMS heated resonators for environmental monitoring applications.

Current research interests

  • Noise, vibration, and harshness (NVH) in electric vehicles (EV).
  • Design development and characterisation of multi-sensing miniaturised sensors (MEMS-based sensors) for environmental and automotive condition monitoring. She is also interested in fundamental knowledge of nonlinear dynamics of these MEMS sensors which are crucial for their safe implementations.
