Research Work Title:  Nano- and Microfabricated Hydrogels for Regenerative Engineering   

Abstract:  

Engineered materials that integrate advances in polymer chemistry, nanotechnology, and biological sciences have the potential to create powerful medical therapies. Prof. Khademhosseini has engineered tissue regenerative therapies using water-containing polymer networks, called hydrogels that can regulate cell behavior. Specifically, he has developed photocrosslinkable hybrid hydrogels that combine natural biomolecules with nanoparticles to regulate the chemical, biological, mechanical and electrical properties of gels.  These functional scaffolds induce the differentiation of stem cells to desired cell types and direct the formation of vascularized heart or bone tissues. He has pioneered concepts of making conductive hydrogels by integrating nanomaterials including carbon nanotubes, graphene, and reduced graphene oxide into materials. To create tissue complexity, he has also developed directed assembly techniques to compile small tissue modules into larger constructs. It is anticipated that such approaches will lead to the development of next-generation regenerative therapeutics and biomedical devices.

Biography :

Prof. Ali Khademhosseini is a Professor of Medicine and Health Sciences and Technology at Harvard-MIT’s Division of Health Sciences and Technology and the Harvard Medical School.
