Profile

My first degree was in electronic engineering at University College London. I continued at UCL to complete a PhD in physical electronics. After that I started work at the GEC Research Laboratory in North Wembley conducting research into optical methods for characterisation of semiconductor materials. In 1988 I joined Oxford as a lecturer and Fellow of Trinity College. I have had sabbaticals at university research laboratories in Japan, Sweden and USA.

Teaching

My tutorial teaching at Trinity covers all the electrical engineering topics and part of the mathematics syllabus. These tutorials are given in small sizes of 2 or 3 students. I also give the tutorials on Engineering in Society, which is best covered in a larger class containing all the Trinity students in one year group (5-6 students). I share Trinity’s tutorial teaching with my engineering colleagues Alexander, Felix and Michael. As the senior engineering tutor I organise the teaching timetable. In the Department of Engineering Science I give lecture courses on electronics and organise laboratory sessions. I am currently Associate Head of Department, responsible for teaching.

Research

My research is divided between two themes at present. The main activity is in the area of biomedical engineering and involves research into fluidic devices that can be used for the detection of disease. These devices use a combination of specially sensitised magnetic particles and optics. The second theme is optical engineering. I’m working with industry to develop optical sensors for the waste water industry, which involves measuring low levels of light scattered from turbid water to determine if it is safe to drink. In the recent past I have worked on nanoparticle technology for producing coloured architectural glass and computer generated holography.
