52Department 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 BiologyUsing micromanipulation to study the mechanism of fertilization and preserve, regenerate, and utilize genetic resourcesMy lab studies physiological aspects of early events during fertilization in mammals as well as technical innovations involving the preservation and utilization of genetic resources. My students and I have published more than 100 research papers so far describing our research into haploid gametes (spermatozoa and oocytes) and diploid embryos from various mammalian species, including mice, rats, rabbits, cats, horses, buffalo, cattle, whales, and humans.Professor Hochi took his current position in 2008 after working as a researcher (1986 to 1992) at Snow Brand Milk Products Co. Ltd., as a visiting assistant professor (1992 to 1995) and visiting associate professor (1995 to 1996) at Obihiro University of Agriculture and Veterinary Medicine, and as an assistant professor (1996 to 1999) and associate professor (1999 to 2008) in the Faculty of Textile Science and Technology at Shinshu University. He is engaged in research on reproductive physiology, cryobiology, and developmental engineering in small experimental rodents, large domestic animals, and humans.Advanced reproductive technologies such as intracytoplasmic sperm injection and somatic cell nuclear transplantation made it possible to bring the mammoth back to life. Furthermore, we have recently established pluripotent stem cell lines in laboratory rats. If these ES or iPS cells could be dierentiated into functional gametes, the process would be the ultimate treatment for infertility.Outlook for researchGraduates are employed by pharmaceutical and food-related companies as well as national and local organizations (as public ocials). In what has become a recent trend, some skilled graduates work at human infertility clinics as potential embryologists.Outlook for students after graduationIntracytoplasmic injection of shhook-shaped rat sperm heads was dicult to achieve, but several clues helped us expand its application to freeze-dried spermatozoa.Micromanipulation enables us to handle not only oocytes with diameters of 100 to 120 μm, but also much smaller sperm cells.A microtubule network can be assembled from a centrosome of spermatozoon immediately after fertilization.Shinichi HochiProfessor
