Bacterial nanonetworks

Bacteria have a number of appealing properties that makes them ideal and attractive for molecular communications. These properties include, (i) the ability to store genetic information in the form of plasmids (plasmids are a type of DNA), (ii) bacteria have the ability to transfer information between each other (this ranges from emission of chemical signaling to transferring of genetic contents), and (iii) bacteria are able to mobilize and swim in a liquid medium (e.g. E.Coli). Based on these properties, this research is investigating the use of bacteria as information carriers between the nanomachines. The areas of research include developing bacterial mobility models, as well as information coding techniques for plasmids to increase reliability of information transfer.

Neuronal networks

Neurons are a basic unit of a neuronal network, and have tremendous abilities to self-organize and form highly complex networks. Through these complex networks, neurons are able to communicate, where this communication consists of both electrical and chemical signals. Besides communication through wired interconnections, neurons are also able to communicate and interact through electromagnetic waves. This research is investigating the wireless communication capabilities between neuronal cultures.

Calcium signaling

alcium 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.
