I use next-generation instruments to better detect and characterize planets orbiting nearby stars, with a particular focus on planets orbiting low-mass stars. To study these worlds, I leverage data from two precision radial velocity spectrographs I helped design and deploy—the near-infrared Habitable-zone Planet Finder (HPF) on the 10m Hobby-Eberly Telescope, and the optical NEID spectrograph on the 3.5m WIYN Telescope—along with the diffuser-assisted photometry technique, a low-cost method I have shown is capable of approaching space-quality photometry from the ground.
