Research Interests
My research interests focus on the formation and evolution of galaxies in the very early universe. I primarily use the James Webb and Hubble Space Telescopes to find and study high-redshift Lyman-break galaxies, including those gravitationally lensed by massive galaxy clusters.
Current JWST Science Teams
- JWST Cosmic Spring
- Vast Exploration for Nascent, Unexplored Sources (VENUS)
- Prime Extragalactic Areas for Reionization and Lensing Science (PEARLS)
- Bias-free Extragalactic Analysis for Cosmic Origins with NIRCam (BEACON)
Past Hubble Leadership & Science Roles
- Deputy Principal Investigator, Reionization Lensing Cluster Survey (RELICS)
- Science Advisor, Hubble Frontier Fields program
- Member, Cluster Lensing and Supernova survey with Hubble (CLASH)
- Member, Brightest of Reionizing Galaxies (BoRG) survey
- Member, Advanced Camera for Surveys (ACS) GTO Science Team
My Ph.D. dissertation focused on Hubble Space Telescope (HST) / Space Telescope Imaging Spectrograph (STIS) observations of the kinematics and ionization structure in the narrow-line region (NLR) of Seyfert galaxies.
