Dr Matthew Praeger is a Research Fellow at the ORC, currently working within the FAST Lab. This group specialises in laser machining with femtosecond pulsed laser systems and has pioneered advanced beam control methods via the use of Digital Micromirror Devices (DMD)s.
This beam shaping technology is applicable in many related fields with laser transfer of materials being of particular interest as a potential new method for high resolution additive manufacturing. Specifically, Laser Induced Forwards Transfer (LIFT) and Laser Induced Backwards Transfer (LIBT) are under investigation as a means of transferring 2D materials, such as graphene, in order to fabricate silicon photonic devices.
Dr Praeger's other research interests have included nanocomposite materials, high-voltage electrical engineering, microfluidics and electromagnetic phenomena. The pursuit of these has been assisted by strong computer programming and Computer Aided Design (CAD) capabilities along with a desire to automate and mechanise experimental data collection wherever appropriate.
Recently the group has published several papers in which artificial neural networks are used to process experimental data. Building upon this foundation, the group aims to use A.I. algorithms for the control of lasers and laser machining systems. Such technology could offer large-scale efficiency and quality improvements across the industrial manufacturing sector.
