As a mechanical engineer who can commnicate with material scientists since I have been working on thermal transport in nanostructure thermoelectric materials ever since the first year in my Ph.D., 2001, I would like to contribute the International Thermoelectric Society (ITS) in the following way. During the last a few decades, there have been tremendous progress in zT. While we should be continue working on enhancing zTs of materials, I can recruit system engineers like mechanical, electrical, chemical engineers and so on, to this ITS so that, at the same time, we can put effort to produce innovative product on market out of those existing high zT materials, which would lead more attention to our thermoelectric community.
