Hiroyuki Chihara is a Japanese mathematician who has been working on microlocal analysis in integral geometry since 2020. Roughly speaking, this is a field of mathematics related to the mathematical principles of CT scanners. Recently he is working on the microlocal analysis of integral transforms such as geodesic X-ray transform on Riemannian manifolds.
He is also interested in medical imaging, security inspection, seismology, ocean science, non-line-of-sight imaging, and computer vision. Microlocal analysis plays a crucial role in such topics in applied mathematics.
He likes learning applied mathematics and programming languages such as MATLAB and Julia Programming Language. For example, in 2023 he studied the basics of geometric deep learning reading a new textbook to be published. He is currently a general member of AMS and SIAM respectively.
