Research Topic<\/h5>\n

Exploring the First Billion Years of the Universe with Supermassive Black Holes<\/p>\n

Astronomy is the ultimate means of tackling humanity\u2019s fundamental questions: Where do we come from? What are we? Where are we going?<\/em> I aim to explore the answers to this grand mystery by observing supermassive black holes that existed in the first 10% of the Universe\u2019s 13.8-billion-year history using ground- and space-based telescopes. Specifically, I focus on the early growth of supermassive black holes, their co-evolution with their host galaxies, and their impact on large-scale structure formation.<\/p>\n
