Dr. Man Yi Ho

email: myh20

Dr. Man Yi Ho studied her first degree in Electrical and Electronic Engineering at University of Cambridge, graduating with a MEng in 2006. She subsequently pursued a PhD in Biosensing which focused on the development of label-free electrochemical detection of biomolecular interactions using redox active self-assembled monolayer, and the theoretical modelling of the electrochemical biosensor. More recently, she is involved in

  • Electrochemical aptamer-based sandwich assays for the detection of explosives
  • Multiplexed detection with thin film transistors
  • Amplification of Avian Influenza virus gene with polymerase chain reaction and the subsequent detection with PNA probe

Dr Man Yi Ho is now a Researcher at Schlumberger Gould Research in Cambridge.




Professor Shien-Kuei Liaw


Professor Liaw received a double doctorate degree in photonics engineering from National Chiao-Tung University and mechanical engineering from National Taiwan University of Science and Technology respectively. He was an academic visitor at Bellcore (now Telcordia) and University of Oxford. He owns 40 patents; authored and co-authored 250 journal articles and international conference papers in the fields of optics and photonics.

Dr. Liaw's expertise is in:

  • Fiber Bragg gratings and fiber based devices implementation
  • Optical fiber communication and optical wireless communication
  • Fiber sensing technologies and reliability testing

Currently, Dr. Liaw is a Distinguished Professor and Vice Dean of National Taiwan University of Science and Technology, the President of the Optical Society (OSA) Taiwan Section and Secretary-General of the Taiwan Photonic Society. Dr. Liaw is a senior member of IEEE Photonics Society, OSA and SPIE.  




Introduction of CPDS

Centre for Photonic Devices and Sensors (CPDS) is in the Photonics area of the Electrical Engineering Division, with a research focus embracing photonic and sensing devices, functional materials and their integration at system level.

We aim to address future societal needs with new system functionalities through invention of novel device architectures based on in-depth understanding of basic material properties.

There is a wide range of activities within the group, including phase-only holography and its applications, high brightness multi-stable colour reflective displays, tuneable dielectric materials and devices for radio frequencies, liquid crystal on silicon (LCOS) device development, and novel sensors.

As well as conducting highly focused studies, we also specialise in the development of demonstrators for business exploitation and commercialisation. This is facilitated by multi-disciplinary expertise within the group and by our highly experienced team approach. Some of the outcomes from the group have been successfully transferred to our industrial collaborators for production.
