Dr. Marta Ximenis Campins is a group leader at Catalysis and Sustainable Polymers. Her work lies at the interface of organic chemistry, catalysis, and sustainable materials. Her research focuses on the design of functional polymeric systems, dynamic covalent networks, and circular polymer technologies, with particular emphasis on developing innovative synthetic strategies that combine molecular design with advanced material performance. She obtained her PhD in Chemistry from the University of the Balearic Islands, where she worked on squaramide-based stimuli-responsive molecular systems and supramolecular chemistry. In 2020, she joined the laboratory of Prof. Takashi Uemura at the University of Tokyo as a postdoctoral researcher, where she spent two years developing two-dimensional polymer networks using metal-organic frameworks as template nanoreactors. In 2022, she joined POLYMAT – Basque Center for Macromolecular Design and Engineering as a postdoctoral researcher under the Margarita Salas Fellowship and then as Gipuzkoa Fellow. In December 2024 she was appointed Emakiker Fellow, and she is currently developing independent research activities in sustainable polymers, organocatalysis, dynamic materials, and chemical recycling. Her work has contributed to the development of covalent adaptable networks (CANs), vitrimers, recyclable thermosets, and novel polymerization methodologies aimed at improving the sustainability and circularity of polymeric materials.
