I recently developed a miniature implantable oxygen sensor, manufactured at the Scottish Microelectronics Centre using advanced microfabrication processes. It has been extensively tested in vivo for use in cancer radiotherapy treatment (IMPACT) and post-surgical tissue monitoring (ATOMIC). I have also contributed to the design and fabrication of a "smart stent", which contains a miniature sensor for detecting neointimal tissue growth in blood vessels. Currently I work on the Wheels of Change project, developing a multimodal sensor system for a smart wheelchair.
Within these projects I contribute engineering expertise, and also take a leading role in facilitating interdisciplinary communication and knowledge exchange between electronic engineers, medics and vets.
To date, I have 20 published outputs (book chapters, journal and conference papers). I frequently present my research to students at guest lectures (please get in touch if you have a free slot) and assist with teaching on Microelectronics 2 undergraduate course within the E&EE discipline. I have also engaged with the public at the Edinburgh Science Festival, and discussed biomedical research with MSPs at an EPSRC showcase event held at the Scottish Parliament.

Microfabrication & packaging
Development of novel microfabrication processes for electrochemical sensors. Recent work has focussed on wafer-level deposition and patterning of Nafion (an ionomeric polymer), and development of robust thin-film Ag/AgCl reference electrodes. Also advanced packaging methods for implantable sensors, and particularly the use of flip-chip technologies on flexible substrates.
Use of microfabricated electrochemical sensors for monitoring biological processes. Interests include amperometry and impedance techniques, analysis of sensor performance, wearable instrumentation, and development of novel interfaces between synthetic biology and electronic instrumentation.
Design and testing of implantable microsystems for biomedical sensing. This research involves collaborations within IMPACT, led by Prof Alan Murray, and in vivo validation in animal models with Mr Mark Potter (NHS), Prof Mervyn Singer (UCL), and Dr Mark Gray and Prof Eddie Clutton (RDVS).
