Calcium ions are one crucial form of signaling molecules that are used by a number of cells in order for controlling numerous cellular processes. Example cells that utilize calcium signaling include sensory cells, neurons, or cardiomyocytes. The communication process of calcium signaling involves a number of highly complex chemical reactions that releases calcium molecules in response, which in turn opens/closes particular channels on the cell membrane. The result of these reactions leads to diffusion of calcium ions to the neighbouring cells. The area of this research includes modeling the delay and noise properties of calcium signaling, as well as their communication behavior under various tissue deformation.
