51Department of Applied BiologyLearning from the environment through environmental analysis and developingnew environmental purification methods using materials creating by living organismsI am carrying out research in a wide range of domains related to environmental contamination, from environmental analysis and toxicological testing to the development of environmental purification methods. This effort includes numerous activities, for example analyzing litter and searching in caves for microorganisms that might be useful in environmental purification. In recent years, my lab has been focusing on the development of environmental purification methods that use materials produced by living things.Professor Moriwaki took his current position in 2015 after working as a researcher at the Osaka City Institute of Public Health and Environmental Sciences and as an associate professor at Faculty of Textile Science and Technology at Shinshu University.His areas of research include environmental chemistry and analytical chemistry with a focus on the development of environmental purication and analysis methods as well as environmental monitoring.I believe that understanding the state of environmental contamination while developing purication methods is essential for the future of humanity. Through environmental analysis and research on purication, I hope to obtain results that prove useful in addressing numerous environmental problems.Outlook for researchI carry out education and research to train students to become leaders in the next generation of environmental research and measures. Graduates are employed as public ocials and by companies engaged in environmental analysis and inspection.Outlook for students after graduationWe analyzed mud from the moat of Osaka Castle to recreate 350 years in the history of the atmospheric environment. The aerial bombing during the war caused the greatest damage to the environment.Throughout the world, countless children contract communicable diseases because they do not have access to safe water. In this way, purication is an extremely important research topic.Hiroshi MoriwakiProfessor水質汚濁　世界的に重大な問題新しい浄化法生物資源の利用・安全かつ環境にフレンドリー・低コスト・廃棄物利用注）写真はイメージ図です。　安全な水を作る！・羊毛・くず繭・バイオポリマー水質汚濁　世界的に重大な問題新しい浄化法生物資源の利用・安全かつ環境にフレンドリー・低コスト・廃棄物利用注）写真はイメージ図です。　安全な水を作る！・羊毛・くず繭・バイオポリマーWater pollutiona serious global problemuse of biotic resources・wool・Waste cocoons・biopolymer・safety and environmentally friendly・low cost・recycling of wastenew catharsisMake a safety water!Department of Applied BiologyDesigning and applying useful proteins by studying the structure and function of proteinsI am carrying out research to gain a deep understanding of the structure and function of proteins and to design, develop, and apply useful modified and artificial proteins. Based on my goal of achieving results that will prove useful in addressing biological resource issues and environmental problems, my lab uses cutting edge chemistry to see, examine, create, and apply proteins.Associate Professor Arai took his current position in December 2007 after working as a researcher at RIKEN and Princeton University in the U.S. His areas of research are structural biology, which he uses to examine the three-dimensional structure and function of proteins, and protein engineering, which he uses to nd applications for proteins through their modication and design.My goal is to apply proteins in new elds, for example in pharmaceutical development and biotechnology, in order to create eco-friendly high-function nano-materials, clean chemistry catalysts, and high-sensitivity biosensors. In this way, I hope to contribute the achievement of a sustainable and abundant society.Outlook for researchGraduates are employed in numerous elds, including at pharmaceutical, enzyme, and chemical companies.Outlook for students after graduationSelf-assembling nano-architectures are created from a protein　nano building block by fusing a dimeric de novo protein WA20 and a trimeric foldon domain from T4 phage.
