Current Interests

1. After the earthquake disaster in Japan, my most interests are to visualize and keep a record of what happened in Japanese economics fields owing to the quake. Using twitter data, we would like to visualize these things so that even children could understand what happened. In addition, the Asian Currency Crisis in 1997 is also one of our research targets. I believe that these disaster and crisis will have to be matters that we should convey to a young generation
2. In my classes of business mathematics, deduction process graphs are used. The graphs are drawn by our developed tool called Solution Plan Graph Generator with the formula database (See the sample of the first graph). For example, when I teach the Black-Scholes Model, I use the deduction process of which unknown is the Black-Scholes equation (See the sample of the second graph).
Sample visual materials in English are available at
http://www-cc.gakushuin.ac.jp/~20010570/mathABC/ and
3. Concerning multi-cultural research, we have started a joint research with a female professors of Chulalongkorn University, Thailand. This research purpose is to spot the differences between Thailand persons and Japanese persons on SNS messages concerning the assistance for reconstruction of Japan after the great earthquake in 2011.
4. In June 2012, we have published an e-Book of finance mathematics from O'Reilley Japan. I have developed various interactive visual materials for mathematics. Using the teaching materials, I teach (financial) mathematics in many schools and universities. For example, as a public lecture of Gakushuin Univ., I taught economics mathematics for students at the University of Indonesia in March, 2013 and 2014.
