Technical Research Summary
A major theme of my research is to understand the nature of the first galaxies and the ensuing cosmic phase transition known as the Epoch of Reionization. I lead the THESAN and THESAN-ZOOMS (www.thesan-project.com) simulation campaigns to produce realistic galaxies and synthetic observations, enabling a more fruitful exploitation of current and forthcoming data. I am the author of the state-of-the-art COLT (colt.readthedocs.io) Monte Carlo radiative transfer and AREPO-MCRT moving-mesh radiation-hydrodynamics codes. My research spans multiple subfields in astrophysics and provides strong synergy with theory and observation.Publications
