Personal statement

Michael Lengden was awarded an M.Phys. degree in physics from the University of Manchester, where he also received the Ph.D. in 2006 for his work on stepwise excitation of atomic and molecular metastable states. 

After spending a year as an applications engineer for Laboratory Impex Systems LTD he joined the Centre for Microsystems and Photonics at the University of Strathclyde as a Research Fellow working on high temperature, high pressure gas composition measurements using tunable diode laser spectroscopy.  In 2010 hw was appointed as a lecturer within the EEE department and is currently applying new techniques in tunable diode laser spectroscopy for concentration and pressure measurements in harsh environments, such as solid oxide fuel cells and aeroengines.

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.
