Research Description

Mechanical Engineering is based on various disciplines of mechanics and dynamics. We make emphasis on the viewpoints from statistical mechanics and dynamical systems theory, in order to make full use of the physical characteristics covering the nano/micro spatio-temporal scales. This is partly because the systems of interest show incessant thermal fluctuations, which has long been regarded as just a noise in the engineering context. However, the phenomena caused by thermal fluctuations such as Brownian motion are essential if it comes from the systems of interest themselves. In fact, such manifestation of thermal fluctuations often includes valuable information in the measurements. We are developing theoretical methods suitable for the big data of nano/micro systems. Our viewpoints are recently getting more and more appreciated from the experts of various development-oriented fields due to the necessity in the course of innovations.

About TUAT's tenure-track program

Although achievements are supposed to be evaluated by numerically in the tenure track system, the chance to try original ideas of visionary researchers is of fundamental importance in their career, which can lead to the qualitative difference in the history of science and technology in the long term.

Future aspirations

Although technological innovations and theoretical sciences are regarded to make stark contrast with each other, the former can sometimes be triggered and even achieved by the latter. This is because even spontaneous trials for technological developments are in fact based on some kind of unperceived assumptions. Sensible combination of theoretical insight based on the firm ground of physics and technological developments based on the accumulated knowledge of sophisticated expertise will realize the innovations that the academia can provide, which is still far from fully appreciated.
