Welcome to my site! Here you can find some of my research interests, teaching activities and materials of the past years, as well as my publications (article links and preprints), ongoing projects, conference participations, editorial issues, and collaboration stays. I will try to keep this web-page as updated as possible, although, if you find that something is missing, please refer yourself to my profile on Google Scholar or ResearchGate.
My Job as a Researcher
I hold a permanent position (with full-time dedication) as an Adjunct Professor of the Universidad de la República (UdelaR), Uruguay (Associate Professor and Professor are the remaining positions in the tenure track). My position is based at the Department for Theoretical Physics of the Physics Institute in the School of Sciences (IFFC), requiring: teaching (~30%), research (~30%), administrative duties (~10%), and student supervision (~30%). Since June 2020 I am also a Research Fellow of the Aberdeen Biomedical Imaging Centre (ABIC), University of Aberdeen (UoA), Scotland. My RF appointment corresponds to a 2 year project involving the development of novel neuroimaging-informed ways to classify Alzheimer’s disease and mild cognitive impairment at the ABIC. Also, I was appointed as an Honorary Research Fellow of the Institute for Complex Systems and Mathematical Biology (ICSMB), UoA, from January 2020 until January 2021.
I also worked at the IFFC in Uruguay from 2007 until 2011 as an Assistant Researcher, doing Teaching Assistance and helping in research within the Non-linear Physics Group (NLP webpage). During those years I taught laboratory courses on electronics and modern physics; impart tutorials on wave mechanics, Lagrangian and Hamiltonian mechanics, and non-linear physics; and undertook intern-ships at the Acoustic-Optics Laboratory (acustoptica.fisica.edu.uy) and at the Laboratory of Fluid Instabilities, which is the experimental branch of the NLP group.
My Research Interests
My research interests are focused on Complexity issues. In general, the complex systems that I research involve Coupled Dynamical Systems, namely, many non-trivially interacting sub-systems. I try to measure, explain, predict, and control their collective behaviour in terms of how they are inter-connected, namely, in terms of the topological features of the underlying network topology -- Graph Theory. In particular, I am fascinated by Network Neuroscience research, where Complexity challenges abound -- neurons in the brain create a myriad of dynamical behaviours due to their intricate connectivity in order for us to function and our observations can only access these behaviours by indirect measurements (such as EEGs or MRIs). What happens when a disease affects the brain connectivity? How do we manage to infer the connectivity from indirect measurements? What can we say about the different states of consciousness? How can we develop/improve methods to understand all these issues? These (and other) questions are part of my currently interest.
I am also interested in Fluid Dynamics, specifically, in turbulence and numerical simulations of Navier-Stokes equations; in the mathematical properties of Non-linear Dynamical Systems, mainly in relation to bifurcation theory; in Non-equilibrium Statistical Mechanics, with a focus on the statistical properties of semi-conductor Lasers with optical feedback and of neural/biological networks; and finally, in Information Theory and Data Analysis. Some of these topics I will surely be covering in the following years and I will be uploading documents to this site as I progress into these fascinating areas.
A Short Biography
I have a Ph.D. in Physics  from the UoA and a M.Sc.  and B.Sc.  degrees from the UdelaR. My Ph.D. at the ICSMB, UoA, started in October 2011 under the supervision of Dr. Murilo S. Baptista and Prof. Celso Grebogi. My dissertation was entitled "The mathematical principles behind the transmission of Energy and Synchronisation in Complex Networks" and it was conferred with Honours. The thesis also was nominated to the Springer theses award by the UoA as an outstanding thesis, which won and was published as a book (ISBN 978-3-319-22216-5). Its outcomes are framed within Complexity Science, involving exact and approximate results for the behaviour and stability of complex systems, which are valid for a wide range of complex systems but particularly suitable for the modern power-grid models. Before my Ph.D., I graduated from the B.Sc. in July 2008 and got my M.Sc. degree on "Synchronisation of coupled electronic oscillators" in July 2010 under the supervision of Prof. Arturo C. Martí and Dr. Cecilia Cabeza. The thesis considered the case of an electronic oscillator model, implemented experimentally under a dual RC circuit, which could interact by means of light pulses as a firefly. We also studied the system analytically and numerically obtaining some general conclusions for generic piecewise oscillators.
