Research

Developing MEMS transducers, optical and radio frequency (RF) MEMS devices and systems
Developed several MEMS devices that have many promising applications in optical, radio frequency (RF) and bioscience fields, such as in miniaturized optical imaging tools, miniaturized high voltage devices in power engineering and spectroscopic biosensing applications.

Current research efforts focused on:

Integrating MEMS devices with their interface electronics (supported by an EPSRC grant)
Developing novel measuring devices and systems for bioscience applications (supported by the Royal Society)
Investigating micro power scavenging devices (supported by the Leverhulme Trust)

Teaching

  • EG-151 Microcontrollers

    This module introduces basic microcontroller structure and operation.

  • EG-252 Group Design Exercise

    The module is intended to reinforce aspects of Engineering Applications (EA1) and develop EA2. Advanced features of microcontroller operation are introduced, including interrupts and programming of features of the selected microcontroller. Extended experimental work is carried out as a Group Design Exercise. Practice in using technical IT packages including microcontroller software development and the use of design aids such as PCBs and engineering drawing is inherent.
