Dr. Tani was born and grew up in Japan. He received his BS, MS and PhD in Aerospace engineering from University of Tokyo in 2006, 2008 and 2011 respectively. His PhD work was about the numerical modeling and experiments of the cryogenic fluid mixing at supercritical pressures in the consideration of cryogenic propellant injection in liquid rocket engines. After two years of postdoctoral work in Japan Aerospace Exploration Agency (JAXA), he started a career as a research engineer in JAXA. While continuing study on cryogenic fluid mixing, he had a project to develop a rarefied gas flow simulator to evaluate the risks of space missions with the re-entry to Earth or the rendezvous to International Space Station.

In 2014, he also began to study the hypergolic combustions of spacecraft propellants, e.g. hydrazine, monomethylehydrazine, for the fuel and dinitrogen tetroxide and nitric acid for the oxidizer. His interests are to establish numerical models to estimate spontaneously ignitions of the hypergolic propellants and to validate them by experiments. In November 2016, he joined the Green group at MIT on JSPS postdoctoral fellowship for research abroad. He will learn and apply RMG to chemical kinetics of hypergolic propellants and implement them in his CFD modeling.
