About my research: My main area of research is focused on the detection and characterization of Galactic halo substructures, relics of its hierarchical formation  (as suggested by Lambda-Cold Dark Matter simulations). I am interested in the study of  Galactic stellar clusters to unveil the overall structure of the Milky Way and its origin.

About my research: Massive stars live fast and powerful lives and die young with a bang, leaving lots of marks to their host galaxies. My research focuses on the observation of mass and energy lost during different evolutionary stages of massive stars. Of particular interest is the interactions of these exerted matter and energy in multiple stellar systems, in clusters and in galaxies, either with other stellar winds or with the interstellar matter. One result of the interactions of stellar winds of massive stars is dust formation as observed around some massive stars in our Galaxy and in other galaxies. The puzzle I am trying to unravel is how dust can form in the violent environs of stellar winds of massive stars.

About my research:
My research goals are to better understand how planets are formed. To date we have discovered thousands of exoplanets, with a huge diversity in terms of mass, semi-major axis, and architecture. But from an observational point of view, we don’t really understand how these planets form. To tackle this challenge, I focus on the study of the circumstellar disks, which are the birthplaces of these planets, as well as direct detection and characterization of planets. By characterizing the evolution in time of these circumstellar disks, we have the chance to better understand the conditions that can lead to the formation of giant and terrestrial planets. Direct observations of young planets can give us valuable insight into their formation mechanism, which is currently poorly constrained. 
I have always been interested by a multi-technique (spectroscopy, imaging, interferometry), multi-wavelengths (near-, mid, far-IR and mm) approach, and I always try to combine both observations and modeling of these data. I have a strong interest in leading statistical studies, in order to better understand classes of objects as a whole, but I also enjoy leading detailed studies of individual sources where you can get an in-depth understanding of the physics at stake in these systems at a given time.

About my research: My work is focused on the simulation of close compact binary stars, and the comparison of these with observational data. The aim is to achieve a better understanding of the common envelope phase, a phase that most of these stars undergo, which is a clue for understanding the evolution of some of the most interesting objects in the universe, such as type Ia supernovae, cataclysmic variables, or close double white dwarfs, to name a few. In addition, the recently suggested possibility of planets around evolved close compact binaries has raised the interest in knowing how they might have formed.
