Physicist by formation, I have always been attracted by biological systems and interdisciplinary research. In particular, theoretical approaches and mathematical modeling offer a useful tool to investigate the charming complexity of this kind of systems, looking for some fundamental principles or simply testing our capacity to describe their behavior.

During my thesis and post-doctoral activities, I had the opportunity to familiarize with several biological systems, from the molecular to the cellular level, using different approaches and mathematical formalisms (quantitative and qualitative approaches, discrete and continuous models, stochastic and deterministic descriptions).

I'm currently interested in plant biology and ecophysiology, trying to understand the links between ecological factors (i.e environmental conditions, cultural practices etc) and the underlying molecular mechanisms that determine fruit quality and composition. The different scales involved and the lack of detailed knowledge can make the system difficult to be dealt with classical ODE methods. Several strategies will be explored, including reduction methods, based on ANN, statistical analysis or time-scale approximations, qualitative and hybrid approaches.

A sketch of my CV and main research experiences is reported in the following.
