Personal profile
Research interests
I am a post-doctoral researcher at the University of Bath as part of the interdisplinary project 'u-Care.' I work on developing hollow optical fibres and systems for UV-C light (200-220 nm). u-Care will exploit cutting-edge techniques in laser physics to develop new sources of deep UV light which are compact and robust. We will develop ways to precisely deliver this light for new therapies that target some of the biggest challenges facing medicine: cellular-precision cancer surgery, and the emergence of drug-resistant “super-bugs”. If you are interested in UV fibres for wavelengths not possible in solid-optical fibres, then please contact me.
I am particularly excited by research that allows me to develops novel optical systems and optical fibres for applications. I am interested in controlling light with optical fibres, and in designing and making novel fibres and fibre devices for practical applications. I have an extensive background in optical fibre fabrication, splicing, interconnection, packaging of optical fibres for robust handling, and simulation of optical fibres.
