He received his Ph.D. degree in mathematical sciences from the University of Barcelona in 2005. His main interest is in population dynamics applied to ecology and epidemiology. He has worked on structured population dynamics, models for biological evolution, and epidemic models with the formalism of the complex networks (systems of many elements with a nontrivial pattern of connections). The mathematical tools he uses are ODE and PDE (transport and reaction–diffusion equations) and also stochastic simulations when dealing with models of epidemic spreading. He made a postdoctoral research stay at the University of Trento during 2006 and 2007, and he is co-author of several papers in international journals and conferences.
