## Lagrangian turbulence and particles

I am particularly interested in the **Lagrangian description** of turbulent flows, that is, from the point of view of ideal fluid particles that perfectly move with the flow. I am also interested in more realistic inertial particles â€“ whose dynamics is affected by parameters such as their mass, size or shape â€“ and their interaction with a surrounding turbulent flow. Examples of such particles can be found in a myriad of natural and industrial contexts, but also in laboratory flows, where they are often used to probe turbulence.

## Quantum turbulence

Besides studying the flow of classical fluids, I am also very interested in **superfluids** with little to no viscosity. One important example of a superfluid is liquid helium at temperatures close to the absolute zero. Such fluids are interesting â€“ among many other reasons â€“ because they display the presence of **quantised vortices**, extremely thin vortex filaments about which the velocity circulation takes discrete values. I am particularly interested in the complex turbulent dynamics that can take place in the presence of many of such mutually-interacting vortices, and on how this **quantum turbulence** closely resembles classical turbulent flows in certain aspects. My ultimate motivation is to enable a better understanding of classical turbulence through the conceptual simplicity of the ideal vortex filaments found in quantum flows.

## Scientific computing

My research mainly follows a theoretical and numerical approach. In particular, I perform **direct numerical simulations** of the incompressible Navierâ€“Stokes equations describing classical flows â€“ as well as of different models describing superfluids. My approach is one of high-performance computing, using massively-parallel solvers which can run on high-end supercomputers. I also conceive and implement highly efficient algorithms enabling the analysis of the large amounts of data which are generated by such simulations. This is greatly facilitated by the **Julia** programming language, in which I have developed a number of open-source libraries enabling the large-scale simulation, analysis and visualisation of turbulent flows â€“ among many other applications.
