Geometric Modeling Research Group

The objective of the research

We aim to understand the real-world phenomena using geometrical tools, emphasizing tools in discrete and computational geometry.  In the group, we formulate the real-world problem into geometry problems and solve those problems using geometrical tools. We also solve discrete geometry problems and construct geometric tools to solve real-world problems.
