Research
Mohammed A. Yassin: Associate Professor at the Department of Clinical Dentistry, Biomaterials section, who is an expert in the field of Tissue Engineering and Regenerative Medicine. He strives to create novel and innovative biomaterials that can interact with stem cells and induce tissue regeneration. He employs state-of-the-art techniques and methods to design, synthesize, and evaluate these biomaterials for various clinical applications.
His passion for Green Biomaterials: he is fascinated by the potential of green biomaterials to address the global ecological challenges we face today. He believes that by using renewable and biodegradable resources, we can create innovative solutions for tissue engineering and regeneration.
His research goals and methods: His research aims to develop novel and sustainable green biomaterials, such as polymers, ceramics, and composites, that can mimic the natural properties and functions of human dental tissues. He uses cutting-edge techniques to design, synthesize, and test these biomaterials, while minimizing the use of toxic and harmful chemicals. He also explores the use of waste-derived compounds to valorize biomass and reduce environmental pollution.
His research outcomes and impacts: His research contributes to the advancement of green biomaterials science and technology, as well as the promotion of a circular “zero waste” economy. He is collaborating with other researchers and industry partners to translate his findings into practical applications.
