Research interests and presentations
Currently, I am focusing on the structure and the stabilization mechanism of quasicrystalline compounds. I use several different approaches, such as ab initio method, mathematical modeling techniques, etc.

Computer programs: drawing quasiperiodic tilings in the plane
(1) Program 1: AmmannBeenker2pov.pl
(2) Program 2: Penrose2pov.pl
These programs (written in Perl, approx. 300 lines) generate Ammann-Beenker and rhombic Penrose tilings with the grid method. To run with Windows, you need ActivePerl (ver 5.12) and Povray (v.3.6) installed on your computer. These can be downloaded from
http://www.activestate.com/activeperl/downloads
http://www.povray.org/download
The installation is very simple.
Put each of the .pl files into an empty folder. Double clicking the file to run. Then three output files are generated. (The '.pl' extension should be associated with perl command. But usually it is done automatically when you install ActivePerl.) The output files are (1) the tiling, (2) grid lines (3) mapping of the vertices to the internal space. If you open them in Povray and run, each of these objects can be displayed.
