In this manuscript I summarise the work I have carried out in the last 10
years. My research projects are articulated around various fields in
astrophysics having, as unifying theme, the 3D modelling and the observation of
stellar atmospheres. In particular, my field of research covers all late type
stars, from the Main Sequence stars to the advanced stages (red giant and
supergiant stars). My work is based on the quantitative analysis of images,
synthetic spectra, bolometric luminosity, planetary transits of different types
of stars and on the modeling of their atmospheres. They include the use and
development of 3D simunlations that are necessary for the interpretation of the
data obtained with the new instruments equipping the space borne and ground
telescopes. Interferometry and spectroscopy hold a privileged place in my
research. My research themes concern interdisciplinary aspects by addressing
questions related to atmospheric physics in relation to 3D hydrodynamic models.
The predictions thus obtained are used to drive a vast campaign of
interferometric, astrometric, photometric, spectroscopic and imaging
observations. Finally, 3D simulations are also directly used to drive the
development of new generation instrument at the VLTI, as well as very large
future observatories and are directly linked to the ESA Gaia and PLATO
missions.
