Andrew’s main research interest is laser materials processing. He has reseached laser direct metal deposition - the formation of multiple-layer metal parts from blown powder using CO2 or diode lasers for over 10 years. Other projects have also covered pulsed laser drilling through thermal barrier coatings, laser cleaving of glass, maufacture of biocompatible dental inserts and laser welding of dissimilar materials. He specialises in modelling laser processes; initially using analytical techniques but more recently via integrated FE and CFD models.
Beyond lasers, his secondary research interest is thermography and the use of infrared signals for condition monitoring of equpment, in particular rotating machines.
