Mechanical Modeling Team (B01-1)

Mechanical Modeling Team (B01) consists of Dr. Ishikawa, who is studying behavioral algorithms of ciliates, and Dr. Ishimoto, who is constructing mathematical models of sperm chemotaxis. Using the methods of biophysics and applied mathematics, the team will mechanically model the responses of various microorganisms, cell-cell interactions, and cell-environment interactions.

Research Subject

Development of an Ethological Simulator Based on Microorganism Dynamics in Physical Environments

This research aims to decipher the algorithms of protist intelligence by mechanically model microorganism dynamics in physical environments.
First, we solve a series of governing equations of conservation laws to obtain the physical quantities of the Diorama and Panorama environments in detail. Next, mathematical modeling of the cellular response is performed to calculate the behavior of individual cells. Finally, we develop an "Ethological Simulator" by calculating the collective behavior of cells and the resulting environmental changes. Using the developed simulator, we will elucidate various behavioral algorithms, such as the behavioral algorithm of sperm, microalgae, intestinal bacteria, and ciliates.

In the experiment on sperm, we will collaborate with Dr. Shiba of group A01. In the experiment on microalgae, we will collaborate with Dr. Ueno and Dr. Shikata of A01. For experiments on ciliates, we will collaborate with Dr. Nishigami. We will build a simulator that can reproduce the experiments of our group as well as other groups, and conduct cell-environment coupled simulations to verify algorithms and provide feedback for diorama experiments.
This group will play an infrastructural role thorough mechanical modeling in the whole group.
