Me

Hello! I am a graduate student in astronomy at the University of Arizona working with Professor Dan Stark. My research is broadly aimed towards better understanding the interplay between very early galaxies (z>5) and the universal phenomenon of hydrogen reionization.

 

Among involvement with other observational efforts, I am leading an MMT/Binospec program to study Lyman-alpha emission from galaxies present when the Universe was only about 750 million years old (z~7), approximately 5% of its current age. This emission can tell us a great deal about how the light emerging from the first galaxies transformed the state of hydrogen (the most common element) throughout the early Universe.
