Health and Environmental Sciences

Our proximate goal is to analyze gene-environmental interactions for development of adverse health effects. As environmental factors, persistent organic pollutants, nutrition and working conditions are within our research scope. Laboratory works, genetic epidemiology and field studies are routinely used to solve the problems. Our long-term goal is to practice preventive measures based on our findings. Candidates with public health mind, from any disciplines, will be welcome.

Research and Education

We are exposed to various health hazards. These are found in routine life styles, diets, environmental pollutants and occupational settings. Changes in environment always have revealed new phenotypes and brought new public health issues. To build rational preventive measures, both susceptive genetic determinants and environmental factors should be taken into account. On this basis, we would like to conduct public health practices.
Currently, following projects are ongoing. The first one is to reveal pathogenesis of Moyamoya disease. We have also analyzed in our laboratory from a viewpoint of preventive medicine against brain infarction and breeding in the childhood. In the second project, we are assessing levels of exposure to persistent organic pollutants in a 30-year span. In this project, we are building the Environmental Sample Bank which is open to the public. We study also the radiation exposure caused by Fukushima Daiichi nuclear disaster. We have still other ongoing projects related to common diseases such as diabetes.
