Research Interests

My main research interests focus on understanding how galaxies form and evolve into the objects we see today. Using multi-wavelength spectroscopy and imaging space-based and ground-based observations, my aim is to determine if the basic principles of galaxy growth models are correct and to empirically characterize the large-scale flows of baryons in and out of galaxies that drive the evolution of galaxies over cosmic time.
