Associate Professor Dr. Lee Hwei Voon is a researcher at the Nanotechnology and Catalysis Research Centre, Universiti Malaya, specializing in catalytic biomass valorisation, waste-to-wealth technologies, and sustainable materials. She obtained her B.Sc. (Hons) in Industrial Chemistry (2008) and Ph.D. in Catalysis (2012) from Universiti Putra Malaysia. Her research focuses on the design and synthesis of advanced catalysts for the conversion of biomass and organic wastes into high-value fuels, chemicals, and functional nanomaterials. Her work has contributed to the development of biofuels (biodiesel, renewable diesel, and refuse-derived fuels), biochemicals (bio-oil-derived hydrocarbons), and bio-nanomaterials such as nanocellulose. She has been recognized among Stanford University's World's Top 2% Scientists for six consecutive years (2020–2025), reflecting the global impact of her research contributions. In 2025, she received the SERD Sustainability Award for her contributions to sustainable development through green catalytic technologies, and in 2026, she was honoured with the Anugerah Cemerlang Universiti Malaya – Kategori Penyelidik Harapan (Bidang Sains) in recognition of her outstanding achievements and promise as an emerging scientific leader.
