Dr. Ancuța Elena Tiuc is Associate Professor at the Technical University of Cluj-Napoca, Romania, holding a PhD in Materials Engineering. Her research activity focuses on the development and characterization of innovative acoustic materials for buildings, with particular emphasis on sound-absorbing composite materials obtained from recycled and bio-based resources. Her work addresses the design, optimization, and testing of porous and multilayer composite systems with enhanced acoustic and thermal performance, contributing to sustainable noise control solutions in the built environment. She has developed patented sound-absorbing materials based on waste polymers, textile waste, sawdust, and sheep wool, integrating circular economy principles into building applications. Dr. Tiuc has published extensively in international peer-reviewed journals and has coordinated and participated in multiple national and international research projects in the fields of acoustic materials, sustainable construction, and environmental engineering. Her expertise includes material characterization, acoustic performance evaluation, and eco-efficient solutions for improving indoor acoustic comfort in buildings.
