I am a Banting postdoctoral fellow at the Institute for Research on Exoplanets at Université de Montréal. My research interests range from the kinematics of stars in the neighborhood of the Sun, young associations of stars, brown dwarfs and exoplanets.

Recently I have been working with data from the recent Gaia mission, which provided us with the direct measurements of distances for a billion stars with an incredible precision – this is a real revolution in our field of research. With these new data, our team identified new groups of stars with the same age and composition (stellar associations), and we found many faint, low-mass members in stellar associations that were already known.

Profile_MKI also work on the identification of cold, planetary-mass objects that are isolated in space and thus not in orbit around a star. These objects are faint and can be located anywhere in the sky, which makes them hard to discover, but they are valuable reference objects to understand the atmospheres of giant exoplanets. This is true because they have physical properties such as temperature, clouds, surface gravity and atmospheric pressure similar to those of giant gaseous exoplanets, but the absence of a bright host star makes it much easier to study these isolated objects, once we know where they are located !

More Details on my Scientific Projects

My main scientific interests are young, low-mass brown dwarfs in the solar neighborhood. I use known young (~8-150 Myr) associations to calibrate their age and investigate their physical properties using various tools such as photometry and spectroscopy. This work aims at improving our knowledge on the initial mass function in the planetary-mass regime, as well as better understanding the atmospheric properties of giant, gaseous exoplanets using planetary-mass objects isolated in space.

A detailed description of my PhD thesis is available here.
