Hiroyuki Chihara is a Japanese mathematician who had been working on partial differential equations and geometric analysis, in particular the analysis of dispersive partial differential differential equations on the Euclidean space and dispersive flows from Riemannian manifolds to almost Hermitian manifolds. Since 2019 he has been working on geometric tomography and microlocal analysis of integral geometry. He is also interested in medical imaging, security inspection, seismology, data science and other applied mathematics related to these areas. He usually prefers computers with Debian based operating system such as Ubuntu, and likes software such as MATLAB, Julia Programming Language, Mathematica and Maxima. He is currently a general member of AMS and SIAM.
