Dr Muhammad Muddasar is an early-career researcher in sustainable materials and energy systems, associated with the Bernal Institute and School of Engineering at the University of Limerick. His academic background spans mechanical engineering, energy systems engineering and materials engineering, with research focused on converting abundant bio-based resources, particularly lignin and other wood-derived polymers, into advanced materials for clean energy technologies. Dr. Muddasar research interests centre on sustainable materials for energy harvesting, energy storage and bioenergy applications. He is particularly interested in lignin-derived hydrogels, porous carbons, ionic thermoelectric materials, supercapacitors, batteries and microbial electrolysis systems for biohydrogen production and wastewater treatment. His work aims to develop low-cost, environmentally friendly and scalable materials that can support the transition to clean and accessible energy. He is also interested in circular bioeconomy approaches, where industrial and biomass by-products are transformed into high-value functional materials. Alongside research, Dr. Muddasar value science communication and interdisciplinary collaboration, especially in projects that connect materials science, electrochemistry, renewable energy and sustainable engineering.
