Professor Tadahisa Iwata's research lab specializes in the development of sustainable polymers and biobased materials, focusing on eco-friendly plastics derived from renewable resources. The lab investigates the synthesis and physical properties of novel polyesters and cellulose-based thermoplastics, particularly those incorporating functional groups like anthraquinone and cardanol derivatives to tailor thermal and solubility characteristics. A key research direction involves regioselective chemical modification of polysaccharides such as Curdlan and cellulose to create materials with enhanced performance for biomedical and environmental applications.

Currently used plastics are mostly produced from petrochemical products, but there is a growing demand for eco-friendly plastics. The use of bio-based plastics, which are produced from renewable resources, and biodegradable plastics, which are degraded in the environment, will lead to a more sustainable society and help us solve global environmental and waste management problems.
Twenty-three patients with severe combined immunodeficiency disease were studied for circulating thymic hormone levels (facteur thymique serique, FTS), 21 prior to treatment by transplantation of bone marrow, thymus or fetal liver. Thirteen showed undetectable FTS activity. Only two had normal levels of this hormone. In serial determinations of FTS activity prior to and after transplantation, patients given bone marrow transplants developed sustained increments of serum FTS activity early in the
