■ Current research
My research is an econometric approach to analyze consumer choice shifts under government policies.
For example, I am studying the impact of changes in consumers' awareness of food products and their place of origin after the Great East Japan Earthquake and the accuracy of such information based on consumer and market surveys. In addition, I am researching the analysis of residents' awareness regarding the installation of solar power in their homes in the pursuit of a carbon-neutral society. Consumer survey research has been conducted in Japan, the U.S., Taiwan, and other countries, and collaborative research has been conducted with researchers in Japan, the U.S., Taiwan, and Indonesia.

In graduate school, I have conducted theoretical and empirical analyses of market power in price dominance in grain trade when vertically differentiated products are included. In addition, I conducted a food supply vulnerability analysis study for UNFAO Ghana and a futures price analysis study for the Kansas Soybean Association and Corn Association.
As a post-doctoral fellow, I participated in the Ministry of the Environment's S10 program and learned a lot from professors at the National Institute for Environmental Studies, the Energy Research Institute, the University of Tokyo, and Sophia University. Here, I have conducted simulation analysis of global environmental changes by the end of the 21st century and the indirect socioeconomic impact effects of global warming.
At TUAT, I conducted consumer choice analysis using surveys, socioeconomic impact assessment of global warming, and market power analysis in trade involving vertically differentiated products.
