Dr. Takuto ("Tak") Ishimatsu is a Postdoctoral Associate in the MIT Engineering Systems Division (ESD). His research interests include space exploration logistics, network and graph theory, and water/energy/transportation systems as well as system safety, astrodynamics, astrophysics, and aerodynamics.
Tak received his Ph.D. in Aeronautics and Astronautics (2013) from MIT. His PhD research was to develop a comprehensive graph-theoretic modeling framework for space exploration logistics and to create optimal logistics networks, particularly in the case where internal sources in the network add complexity to the network selection problem. In his dissertation, he developed a novel network flow model referred to as the generalized multi-commodity network flow (GMCNF) method and applied it to human exploration of Mars. In addition to the space application, he also applied this technique to a multi-dimensional infrastructure network in Saudi Arabia for the CCES Sustainable Infrastructure Planning System (SIPS) project.
Tak's current research focus as a postdoc includes: 1) U.S. intermodal transportation network with a focus on maritime in contrast with land-based alternatives, 2) water/energy infrastructure network in Saudi Arabia with a focus on solar desalination technology, 3) electric vehicle charging station network, and 4) next-generation space exploration logistics.
Tak holds a B.Eng. and a M.Eng. in Aeronautics and Astronautics from the University of Tokyo (Japan) and a S.M. and a Ph.D. in Aeronautics and Astronautics from MIT.
