RESEARCH INTERESTS 

Our research interest is the study of cellular and subcellular processes

taken place in living cells, both excitable (for instance, neurons,

fibroblasts) and non-exictable cells such as pancreatic acinar cells. We

are not only interested in the functionality of dynamical processes in

individual cells but also we are interested in the effect of such dynamical

mechanisms in the emergent behaviour of large networks of cells conected,

for instance, with gap-junctions or, in the case of neural tissue, by means

of chemical synapses together with gap-junctions. An important subject of

our research is, therefore, neural tissue, where with different type of

neuron and synapse models, and different type of network topology, one can

explore the functionality of subcellular process, such as calcium dynamics,

release of neurotransmitters and dynamics defining the opening and closing

of the membrane ionic channels, in the computational capabilities of such

network. 

Under a more physical point of view, in the study of biologically inspired

neural networks which include biophysical processes described and studied

by biologists. In most of the cases of interest the system is not able to

reach an equilibrium steady state. Moreover, we are interested in the study

of how all these biophysical mechanisms interact together (self organize)

to put the system (for instance a neural tissue) in a critical state, which

has been reported to allow the system for a better response under a

changing external stimuli.

FACILITITES 

-Our group is a part of a computational physics group of the University of

Granada, and we have a large number of computational facilities. For

instance, we have a cluster "Proteus" multiprocessor with more than 500

cores, which, at the moment, the most powerful supercomputer in Andalusia.

See link below for further information about the supercomputer

-In addition our group has a computer and seminar room which is very useful

for small workshops (about 20 people).
