My research in a few words<\/h2>\n\n\n\n
<\/div>\n\n\n\n

I study turbulent flows interacting with complex, time-dependent geometries. This research is located at the frontier of engineering, scientific computing, robotics, numerical modeling and biology. In particular, I study flapping flight of flying insects, including the turbulent flow insects generate and are exposed to, using high performance simulations on large scale supercomputers. The development of wavelet-based tools for simulation, modeling and analysis is an important part of my work. It also includes experimental work on flows (PIV) and living animals. All my work is open source.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Below you will find a selection of projects that I work on – to give you an idea of what I am interested in and how I work. In general, my mission at the CNRS is interdisciplinary research – at the interface of fluid mechanics, numerical mathematics, high-performance computing and biology.<\/p>\n\n\n\n

\u25ba Wavelet-based adaptive numerical methods<\/h1>\n\n\n\n
\n
\n
\n

For some years now, I develop in cooperation with Prof. Kai Schneider (Aix-Marseille Universit\u00e9) and DR CNRS Marie Farge (ENS Paris) a new numerical method for computational aerodynamics of animals. The code is called WABBIT<\/a> and it is based on biorthogonal wavelets. These wavelets are used to create a dynamically adaptive grid that automatically refines the resolution where necessary to ensure a given precision, and coarsens it where possible. This strategy ensures optimal usage of computational resources. The code is designed for massively parallel supercomputers.

This work is supported by the ANR-DFG Grant “CVSFIT” in cooperation with Prof. Angla Busse (TU Berlin).<\/p>\n\n\n\n

\u25ba Insects in turbulence<\/h1>\n\n\n\n

Insect are not like human designed aircraft: they fly in an extremely hostile environment. Predators everywhere, obstacles like plants blocking the way. An on top of that turbulence shaking them every which way. Humans fly for fun, animals fly professionally. How they manage to fly despite violent turbulence – that question fascinates me since a long time. <\/p>\n<\/div>\n\n\n\n
