Research Interest

My research involves direct observations of exoplanets, using a combination of high-contrast imaging, spectroscopy, and interferometric techniques. I investigate the atmospheric characteristics of young and self-luminous planets, including their chemical composition, temperature structure, and clouds. In am in particular interested to determine how, where, and when giant planets form at large distances from their star, and to unravel formation signatures from observations of their atmospheres.

Have a look at ADS or arXiv for a complete overview of publications, and Github for developed software packages.
