Teaching

I teach a number of course related to electronics, fundamental physics and optical systems.  I also supervise 3rd year, 4th year and Masters projects based on the development of optical fibre sensors.  My teaching is as follows

• EE107 Electronic and Electrical Principles (Tutor)
• 19207 - Electromagnetism (Lecturer)
• EE473 - Photonic Systems (Lecturer)
• EE986 - MSc Professional Studies (Tutor)
• EE979 - Photonics Centre for Doctoral Training (Lecturer and Project Supervisor)
• 19.496 - 4th Year Undergraduate Individual Projects (Supervisor)
• 19.900 - MSc Individual Project (Supervisor)

Research Interests

My current research interests lie in the application of tunable diode laser spectroscopy (TDLS) for gas sensing applications in industrial process control and harsh environments.  I also work on fundamental spectroscopic measurements of gas species at high temperatures.  I am a PI on an EPSRC First Grant looking at the use of 3D printing for photoacoustic measurements of methane, acetylene and SOx.  I am also a CI on a collaborative EPSRC grant with the Universities of Manchester and Southampton, Rolls-Royce and Shell.  My main focus on this project is the development of TDLS techniques to measure a 2D tomographic distribution of carbon dioxide from aero engine exhausts.
