معرفی
Hiroaki Yoshimura is a Professor of Applied Mathematics and Mechanics in the Department of Applied Mechanics and Aerospace Engineering at Waseda University's Faculty of Science and Engineering. With a career spanning over three decades at Waseda University, he has established himself as a leading researcher in geometric mechanics, dynamical systems, and mathematical physics, with significant contributions to space mission design and thermodynamics.
Yoshimura received his BS in 1986, MS in 1988, and PhD in Engineering in 1995, all from Waseda University. His academic progression shows steady advancement: Research Associate (1992-1995), Assistant Professor (1995-1997), Associate Professor (1997-2003), and Full Professor (2003-present). Notably, he spent the 2002-2003 academic year as a Visiting Faculty member at Caltech's Division of Applied Science and Engineering, working with Jerry Marsden.
Professor Yoshimura's research focuses on the mathematical foundations of mechanics and thermodynamics. His primary interests include geometric mechanics, dynamical systems, and classical field theories, with particular emphasis on Dirac structures, Lagrange-Dirac dynamical systems with symmetry, and applications to nonholonomic systems, circuits, and continuum mechanics. He has pioneered variational formulations of nonequilibrium thermodynamics, bridging mathematical theory with physical applications. His work also extends to practical aerospace engineering problems, including space mission design based on restricted three-body problems, Lagrangian coherent structures in fluids, and mathematical modeling of cavitation bubbles with induced shock waves. His research demonstrates a unique ability to connect abstract mathematical concepts with concrete physical phenomena across multiple disciplines.
Analysis of his recent publications reveals a strong trend toward unifying geometric mechanics with thermodynamics through Dirac structures. His work consistently develops mathematical frameworks that can handle both conservative and dissipative systems within a single geometric structure. This approach has proven particularly valuable for modeling open thermodynamic systems that exchange heat and matter with their environment. In astrodynamics, his research shows innovative applications of tube dynamics and invariant manifolds for low-energy space mission design, particularly for missions involving Martian moons and Earth-Moon transfers.

Professor Yoshimura has maintained active research collaborations internationally, particularly with François Gay-Balmaz on thermodynamics and with aerospace engineers on space mission design. His publication record demonstrates consistent productivity with high-impact contributions, as evidenced by 82 papers cited 687 times in Scopus (h-index 13) and 1,281 citations in Google Scholar (h-index 17). His work has established important connections between geometric mechanics and nonequilibrium thermodynamics, creating new mathematical frameworks for understanding complex physical systems.
Yoshimura's research group at Waseda University focuses on the intersection of geometric mechanics, dynamical systems theory, and mathematical physics. The group maintains strong connections with both theoretical mathematicians and applied aerospace engineers, facilitating cross-disciplinary research that bridges abstract theory with practical applications. Their work on Lagrangian coherent structures has particular relevance for understanding fluid dynamics in both terrestrial and space environments.
