My research focuses on protoplanetary disks, the birthplace of planetary systems. These disks of gas and dust surrounding young stars provide the raw material for planet formation, and by studying them we can uncover the processes that shaped our Solar system and continue to shape planetary systems throughout the galaxy. The central goal of my work is to understand how planets assemble within these disks and why the resulting planetary systems exhibit such striking diversity in their architectures and compositions.
To address these questions, I use state-of-the-art observational facilities, including ALMA and JWST, to probe both the physical and chemical conditions of these disks. With ALMA, my work has revealed that rings and gaps are common disk features, and in certain cases these structures provide clear evidence for ongoing planet–disk interactions. With JWST, I focus on the chemistry of the innermost disk regions where terrestrial planets are expected to form. My recent study demonstrates that disks around very low-mass stars can sustain carbon-rich chemistry for tens of million years, much longer than previously thought, which has important implications for the building blocks of exoplanet atmospheres.
