is a mathematician who has been working on partial differential equations and geometric analysis, in particular the anaysis of dispersive partial differential differential equations and dispersive flows between manifolds. Recently he is working on geometric tomography and microlocal analysis in integral geometry. He is also interested in applied mathematics related to them including medical imaging, security inspection, seismology, data science and etc. He usually prefers computers with Debian operating system, and makes an effort to use software including MATLAB, Mathematica and Maxima.
