Our research group focuses on pattern formations in biological systems using both theoretical and experimental approaches. For example, we analyze morphological changes of three-dimensional micro-conformation in liver during the liver-disease by the quantification of 3D morphology, to reveal the mechanism to self-organize and reproduce the 3D micro patterns. We also study the morphology in the mathematical models by the numerical analysis. These combinations bring about the further understandings of the relations between morphology and their functions.

For the last decade, we have also performed the several studies as follows:

1. 3D periodic patterns obtained by reaction-diffusion systems
2. Behavior analysis of free walking mice
3. A reaction-diffusion algorithm for pattern segmentation
