In the last decades, there has been a huge advance in the understanding of biological processes due to sophisticated experimental techniques, accompanied by an increasing acknowledgment of the importance of theoretical modeling. This modeling has been conducted at a large variety of levels, from the atomic and molecular description to the consideration of the whole organ, individual or community of individuals. Typically each level makes use of a set of specific techniques. However, the interaction of biophysical processes acting at very diverse spatial and temporal scales makes often necessary to consider different levels of description for the distinct elements considered in
the model, leading naturally to hybrid approaches.
The first aim of this project is to handle specific biophysical processes at different scales with hybrid models. The project comprises a series of specific objectives related to both the cell polarization phenomena and pulmonary infectious diseases. On the one hand, polarization is studied from intracellular to cell level (individual ion channels, polarization and cell locomotion), and from cell to tissue scale (calcium waves in cardiac tissue). On the other hand, pulmonary diseases are studied at scales from cell to tissue (granuloma growth and control), and from tissue to individual and population (tuberculosis infection in a virtual lung, and the role of space in its epidemiology). The
specific objectives in each of the bioprocesses have been selected both by their scientific interest and by their potential social impact. The main methodologies used in the hybrid approaches will be agent-based models, reaction-diffusion equations, stochastic ordinary and partial differential equations and/or spatial discrete methods. We will make use of High Performance Computing techniques in the most complex codes, which will be parallelized and run in computer parallel environments.
The second purpose of this project is methodological. All the biological processes included as specific objectives share some common characteristics: (1) they are constituted by discrete elements, from molecular structures in the cellular membrane to a population of individuals; (2) their behaviors have stochastic elements; and (3) it is essential to consider space to understand their dynamics. Given these associations, it is feasible to apply their particular methods at different levels. Based on existing work synergies, our proposal will facilitate the flow of methods between the different scales and discuss transversal aspects of bioprocesses modeling, in the context of an interdisciplinary team. This setting will permit to study questions related to the concurrent use of different modeling approaches, such as
the interaction between reaction-diffusion equations and agent-based models. As a result, a common methodology for the study of complex biophysical systems will emerge.
The project counts on some international team members that have wide expertise on some of the bioprocesses studied. In addition, the research team closely collaborates with external investigators that will provide experimental data, when needed. At present, 3 PhD students are being supervised by our group and will participate in some of the tasks.
