Hossein Hosseinkhani received his Ph.D. degree in Polymer Chemistry from Kyoto University. Thereafter, he was offered the prestigious JSPS Fellowship of Japan at Institute for Frontier Medical Sciences, Kyoto University Hospital to extend his concepts and to develop stem cells technology based on drug delivery systems for tissue engineering applications. Dr. Hosseinkhani was selected as International Center for Young Scientists Research Fellow of Japan because of his creative research in biomaterials science fields. He was a Senior Research Fellow at the International Research Institute for Integrated Medical Sciences, Tokyo Women's Medical University, Japan, and a Visiting Scientist at the Center for Biomedical Engineering, Massachusetts Institute of Technology (MIT), USA. Dr. Hosseinkhani has broad experience in life sciences and is an expert in nanotechnology, biomaterials, drug delivery, 3D in vitro systems, bioreactor technology, and bioengineering stem cells technology. He has long experience in both academia and industry in biomedical engineering research and development, which includes several years of basic science research experience in a number of premier institutions related to the structure and function of biomaterials, and in polymer-based and mineral-based medical implants development in the medical device industry.
