Area of Expertise
I have a strong background in Materials Engineering, and I have more than eight years of R&D experience in material joining technologies that include Friction Stir Welding, Rotary Friction Welding, Gas Tungsten Arc Welding, and Laser Beam Welding for joining complex dissimilar materials (Magnesium-Titanium and Copper-Stainless steel). Additionally, I also have expertise in materials characterisation, including Optical microscopy, SEM, EDX, EBSD, mechanical testing, and non-contact full-field strain measurement techniques such as Digital Image Correlation (DIC). I have a PhD degree in Mechanical Engineering (Materials joining and Characterisation) which was awarded by the University of Southampton. My PhD research delivered a novel high-fidelity experimental methodology to assess the local material response (stress-strain behaviour) of dissimilar welds using a high-resolution DIC technique. During my Ph.D. research, I have delivered extensive research consultancy services to industry-based clients, which received excellent feedback and income to the University. My postdoctoral research project at the University of Manchester has focused on developing a novel soldering process to enable cost-effective high-temperature Pb-free solder interconnects for microelectronics devices. My postdoctoral research involves an in-depth understanding of materials science alongside the application of material characterisation techniques that include small-scale mechanical testing, in-situ synchrotron X-ray imaging, and Electron microscopy techniques to assess the quality of Pb-free solder joints.
