Dr. K.Z.M. Abdul Motaleb is a materials researcher with expertise in sustainable bio-based composites, nano-biocomposites, and smart materials. He holds a Ph.D. in Materials Engineering from Kaunas University of Technology, Lithuania, where he developed sustainable nonwovens and composites from plant waste. He also earned an M.Sc. in Textile Trade and Technology from Hochschule Niederrhein University of Applied Sciences, Germany, and a B.Sc. in Textile Engineering from Primeasia University, Bangladesh. Dr. Motaleb is currently a researcher at Klaipėda University, Lithuania, working on a nationally funded project (NanoBioComp) focused on banana fiber-reinforced biopolymer composites enriched with bio-nanoparticles. His recent research includes micro/nanocellulose–MXene-based 3D-printed hydrogels and films for biosensors and biomedical applications. He previously worked as a Materials Engineer at GRH International Ltd., with hands-on experience in life cycle assessment (LCA), eco-design, and Environmental Product Declarations. He has published over 20 peer-reviewed articles in Q1 journals, contributed to EU-funded projects (Circutex), and received multiple awards, including “Most Active PhD Student” and scholarships from the Research Council of Lithuania.
