I aim conclusive understanding of the human population survival, based on the fieldwork by way of interview and direct observation of demographic , cultural and socioeconomic status, behavior and diet, simultaneously on collecting environmental and biological specimens and those analyses at the laboratory in Japan. I myself intend projection of the effect of anthropogenic modification of any condition in the system and thus I am devoted to construct mathematical models of human population survival. My research fields are the three listed below, mostly included in the Oceania . I have focused on the relationship between malaria and human behavior in People living in northern shore in the Guadalcanal Island, where is widely known as miserable fight at the time of second world war. This condition interested me of nutrition and diet , obesity , and hypertension.
Obesity is also interesting from the viewpoint of thrifty gene .
Now I try to evaluate applicability of the mathematical model based on Papua New Guinea and Solomon Islands to some area in Japan. I have several lectures and practices listed below. In our department, a meeting, to introduce new papers on related study subjects, takes place every tuesday, and I will open the handouts which I made for the meeting since 2001. I have written an HTML textbook in Japanese, which is updated and open to the public. Since 1999, Professor Ohtsuka has this lecture.
