細田・田原 研究室

This is Hosoda and Tahara Laboratory. Thank you for your visiting this site.

We welcome postdoc fellows and visiting scientists who are interested in physical metallurgy and alloy design, especially alloys and composites based on shape memory alloys. Our research topics are materials design, innovation and development for new structural and multi-functional materials and composites used for energy and medical applications. The research field of this laboratory is primary physical metallurgy, and drastic material development and improvement for the innovation of practical applications are also our targets. Not only experimental approaches but also theoretical and calculation approaches such as FEM are focused.

Since this laboratory belongs Institute of Innovative Research (IIR) of Tokyo Institute of Technology, we have been strongly conducting the advanced/frontier researches. IIR is the only one organization of Tokyo Tech which focuses research and technology, and it contains 4 research laboratories. For example, Novel Prize Prof. Ohsumi also belongs to IIR. Our laboratory (Hosoda and Tahara Lab) belongs to two of 4 research laboratories: Laboratory for Materials and Structures (MSL) and Laboratory for Future Interdisciplinary Research of Science and Technology (FIRST). Then, this laboratory is a good choice for the postdoc fellows. However, due to the limitations of space, room, budget and the number of staff, we can accept very limited postdoc researchers, and who have to be financially supported by foundations or you original institutions. We do not pay salary or provide scholarship to postdoc fellows. So, you have to find your scholarship if you want to join in this lab. If you have a permanent position in your university or institute, you may be accepted as a visiting researcher.
