Welcome! I am an Assistant Professor of Physics and Astronomy at the University of Notre Dame. I use observational techniques to discover exoplanets and characterize their fundamental properties.
My research highlights include:
Discovered the transition between rocky and volatile-enveloped planets at 1.5 Earth radii
Discovered the similar sizes and regular spacings of planets in coplanar multi-planet systems (the "peas in a pod" pattern)
Principal Investigator of a NASA/U. Hawaii Key Strategic Mission Support program at Keck Observatory to study the diversity of planet interiors in Kepler's multi-planet systems
Observed >160 nights on Keck-HIRES and Keck-KPF as part of the California Planet Search collaboration.
Experience in self-consistent analysis of Doppler and transit-timing variations/photometry to determine planet masses and N-body orbital dynamics
