During my MSc years we developed a strategy to increase pattern recognition in attractor neural networks. The idea was to reduce the similarity of memories, replacing each one with the pattern resulting from successive iterations of a (pseudo)chaotic cellular automaton rule. We also proposed a new dynamics that improved the Hopfield-Tank approach for solving the traveling salesman problem. Advantages of a neural-network implementation of the latter problem are their direct in-silico and optical implementations.

My PhD thesis is divided in two parts. One deals with small-world networks, their geometric properties and the critical behavior of the average shortest-path length near zero addition of long-range bonds. We prove that the transition from regular to random behavior is first order. On the second part of the thesis nonequilibrium phase transitions are studied. We define a lattice model of structural rigidity and a translation of the latter problem into a reaction-diffusion one, finding numerical estimates of the set of critical exponents of the model.

I have been introduced to the fascinating field of statistical mechanics of complex systems at the beginning of my undergrad years. I have learned many interesting problems like the traveling salesman problem, memory storage and retrieval in attractor neural networks, complex networks and other biologically-inspired problems.

Some of these studies resulted in publications.

Currently, I take part in a team effort developing a computational model for Pseudomonas aeruginosa, a multi-drug resistant pathogen associated with a broad spectrum of infections in humans. My focus is on the reconstruction of its metabolic network.
