My main research interest is addressing the inherently multi scale nature of heliospheric plasmas. Processes such as turbulence, magnetic reconnection, instabilities exhibit a non trivial interplay of the small and large scales. In magnetic reconnection, processes at the electron, ion, and fluid scales coexist and interact. In the solar wind, a large scale process such as solar wind expansion can trigger kinetic scale instabilities, which in turn limit solar wind observable over several AUs, and contribute to shaping the solar wind energy budget. I study these phenomena preferentially within a fully kinetic framework. Fully kinetic codes are notoriously limited by their computational costs. To extend their modeling capabilities, I have developed a modeling infrastructure called the Multi-Level Multi-Domain method, that allows to simulate smaller scale, higher frequency processes embedded in large domains, and a fully kinetic version of the Expanding Box Model, which I use for simulations of kinetic solar wind dynamics. Both codes are based on the semi-implicit temporal discretisation known as the Implicit Moment Method.
While working in numerical modeling, gaining a certain understanding of High Performance Computing and code optimisation is unavoidable.
I have also developed an interest in data-driven analysis techniques, rooted either in Data Assimilation or Machine Learning, which I apply to the study of heliospheric processes.
I am work package leader for the Horizon 2020 project AIDA (Artificial Intelligence Data Analysis), which aims at using ML methods to analyse the ever increasing amount of data coming from heliospheric missions and simulations.
I am a collaborator of the interdisciplinary NASA funded science centre HERMES (HEliospheRic Magnetic Energy Storage and conversion) that aims at furthering the understanding of how magnetic energy is stored and then channeled into plasma motion, thermal and non-thermal energies in different plasma regimes and environments.
