Biographical Details

My main area of research is the formation of massive black holes in the early Universe. Massive black holes shine as extremely luminous quasars less than  a billion years after the Big Bang. Our current models of compact object formation at early times having difficulty reconciling the appearance of Quasars and the formation of the first objects (stars). I work on models which try to understand how supermassive stars may form in the early Universe and may alleviate this tension.
