个人简介

My research focuses on observing the early stages of our Universe using the 21-cm line of neutral hydrogen. This line will allow us to directly study astrophysical processes occurring at the Epoch of Reionization and Cosmic Dawn. Combining my knowledge and experience in radio-interferometry, statistical methods, and software engineering, I develop innovative calibration and data analysis methods to extract and statistically characterize this signal, within numerous international teams.
