Mr. Buddhika Sampath Kumara Sinhasana PS Naidelage is a mechanical engineer and PhD researcher in Biomedical Engineering at Queensland University of Technology (QUT), Australia, supported by an Australian Research Council (ARC) scholarship. He specializes in developing nanostructured surfaces for biomedical implants to enhance biocompatibility and antimicrobial performance, working with Stryker and utilizing advanced cleanroom facilities at the Australian National Fabrication Facility (ANFF). With extensive experience in production plant design, fabrication, piping and instrumentation, and project management, he has led Sri Lanka’s first graphene manufacturing facility at SLINTEC and contributed to TiO₂ production, industrial mixer fabrication, and mineral-based process development. He has also provided consultancy for industrial process optimization, plant layout, and equipment design for multiple government and commercial projects. Recognized with numerous awards, including faculty recognition at Sabaragamuwa University, national scholarships, and research grants from the Asian Development Bank, he is a professional member of Engineers Australia and holds memberships in IEEE, IESL, and the Engineering Council of Sri Lanka. His expertise spans nanofabrication, additive manufacturing, surface engineering, mechanical design, and multidisciplinary project leadership, with a strong focus on innovation, translational research, and stakeholder collaboration.
