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 he 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.
