Recent observations have shown that planetary systems around other stars are much more diverse than originally predicted by theories than can explain our own Solar System. I am interested in understanding the origin of this diversity and how initial conditions in protoplanetary disks impact final planetary architectures.


Stellar-mass-dependencies in exoplanets and disks (Pascucci et al. 2016Mulders, Pascucci, Apai 2015aMulders, Ciesla, Min, Pascucci 2015bMulders, Pascucci, Apai 2015c). Papers 2015a and 2015c provide exoplanet occurrence rates using the Kepler database of exoplanet candidates.

Planet occurrence rates and stellar metallicities (Mulders, Pascucci et al. 2016). We combine the Kepler database of exoplanet candidates with the LAMOST spectral survey of stars in the Kepler field. Exoplanets with orbital periods less than 10 days are preferentially found around metal-rich stars, regardless of the planet radius.



Disk dispersal and giant planet pile-ups (Alexander & Pascucci 2012). The ~1AU pile-up of single RV exoplanets can be explained by migration and quick disk dispersal via star-driven photoevaporation.
