Dr Muhammad Mahmood Ali received his PhD Degree (Distinction) in Photonic Engineering on Bright Sparks Fellowship from renowned Photonics Research Centre, University of Malaya, Kuala Lumpur, Malaysia in 2016. His MS degree in Electronic Engineering (Gold Medal) from the GIK Institute of Engineering Sciences and Technology, Topi, Pakistan, in 2012 and his BS degree in Electronic Engineering (Silver Medal) from The Islamia University of Bahawalpur, Pakistan in 2009.

Currently, Dr Ali is working as a Post-Doctoral Researcher in Centre for Precision Engineering, Materials and Manufacturing Research (PEM Centre), Institute of Technology Sligo, working on a project in collaboration with Abbott Laboratories to “Investigate optimal parameters for the laser welding of polymers” under the supervision of Principal Investigators Dr David Tormey and Dr Richard Sherlock. The project is also the part of the Northwest Centre for Advance Manufacturing (NWCAM) funded by Interreg VA/SEUPB’. Specifically, the project covers the areas of laser physics, laser characterization and control, polymer science, numerical modelling methods relevant to heat dissipation.

Previously, Dr. Ali had been working as a Post-Doctoral Researcher at Optical Fibre Sensors Research Centre (OFSRC), Department of Electronic and Computer Engineering, University of Limerick. During that time, he worked on the development of optical fibre based sensors for biomedical applications and was involved in the development of the automated system for manufacturing those sensors.

He is the co-inventor in the patent on Fabry Perot Interferometer sensor, filed by his principal investigator. In particular, the present invention relates to a pressure sensor of the extrinsic Fabry-Perot interferometric type, a diaphragm for an extrinsic Fabry-Perot interferometric pressure sensor, and a method of manufacturing a diaphragm for an extrinsic Fabry-Perot interferometric pressure sensor. These sensors have been widely used for the monitoring of pressure and acoustic waves in the industrial and the biomedical applications. The motives behind their use are: they are compact, more sensitive, exhibit the high-frequency response, immune to electromagnetic interference, and they can be multiplexed in large numbers on a single fibre with very high data rates at remote locations.

 Moreover, Dr Ali also co-supervised Ph.D. level research theses in university of Limerick and MS level research theses in GIK institute.  He is the guest editor of a special issue of the Sensors Journal titled "optical fibre based pressure and temperature sensors for biomedical and industrial applications" to be publicised in 2021.

Research interests of Dr Ali are in the microwave and photonic devices, fibre Bragg gratings, optical fibre sensor, optical fibre sensors, advanced electromagnetics, digital signal and image processing,  whereas his experience spans from electromagnetics towards laser applications such as laser welding, optical sensing, metasurfaces, metamaterials, and optical based medical devices. He has two Malaysian patents and one EU patent (under filing stage). He has published almost 50 IS indexed, peer reviewed research publications in well recognized OSA, IEEE, Elsevier, Springer journals, and well known conferences with nearly 500 citations to date.
