Biography

Dr. Sinéad O'Keeffe is a Royal Society – Science Foundation Ireland University Research Fellow at the OFSRC. She graduated with BE (hons) in Electronic Engineering from the University of Limerick in 2003 and received her PhD in 2006 from the same institute, for the development of polymer optical fibre sensors for the sterilization industry. On completion of her PhD, she worked as a Marie Curie Research Fellow in the General Engineering Research Institute at Liverpool John Moores University, developing optical fibre sensors for monitoring UV and Ozone. She returned to the Optical Fibre Sensors Research Centre at the University of Limerick in 2008 and was awarded an FP7 Marie Curie Research Fellowship developing radiation dosimeters for monitoring patient doses received during radiotherapy for cancer treatment. She was Chair of the highly successful and recently completed COST Action TD1001 aimed at developing fibre optic sensor systems for reliable use in safety and security relevant applications in society.  She is Member-at-Large of the IEEE Sensors Council for 2017-2018 and Vice-Chair of the IEEE Sensors Council UKRI Chapter (2016-2017). 

Research Interests

Project: Advancing Photonics for Radiotherapy

Funded by The Royal Society – Science Foundation Ireland University Research Fellowship

This project addresses the challenges of delivering effective and optimal radiation treatment for oncology, with specific focus on Low Dose Rate Brachytherapy for treating prostate cancer. It focuses on the need for personalised real-time radiation monitoring during advanced cancer treatments by proposing advances in photonics technology applicable to radiotherapy.

It focuses on the development of highly innovative optical fibre based technology to create in-vivo devices for the diagnosis, assessment and radiotherapy treatment of prostate cancer tumours. Specialist micro-machining techniques, based on femto-second laser and ultra-precision diamond tooling, will allow for miniaturised sensor tips to be incorporated at the end of an optical fibre. The small geometries of optical fibres, coupled with the novel and innovative use of micro-machining technologies, facilitates in-vivo placement of the sensors at the tumour site or nearby critical structures requiring monitoring. Furthermore the development of a fully integrated sensor system, in close consultation with leading clinicians and radiotherapy physicists, will ensure the sensors can be incorporated within current clinical environments in a minimally invasive means.

The measurement of oxygen concentration, coupled with the in-vivo radiation dose measurement, constitutes a powerful combination of leading-edge optical fibre based measurement techniques, providing potential solutions to as yet unresolved problems (reliable and repeatable measurements during the treatment of hypoxic tumours). This opens up the possibility of adapting the radiation dose delivered during the course of the radiotherapy treatment, with a consecutive impact on improving patient outcomes.
