Adrian Liu

Adrian Liu is a Professor in the Department of Physics and a member of the McGill Space Institute at McGill University. He leads the McGill Cosmic Dawn and Hydrogen Cosmology Group, focusing on theoretical and observational cosmology to study the formation of the first stars and galaxies. His research leverages data from radio telescopes like the Hydrogen Epoch of Reionization Array (HERA) to explore cosmic reionization and fundamental cosmology.

Research interests include 21cm cosmology, intensity mapping, and the interplay between astrophysics and cosmology during the Epoch of Reionization. Key projects involve analyzing HERA observations to map large-scale structures and constrain cosmological parameters. Liu collaborates extensively, mentoring students and postdocs in cutting-edge observational and theoretical work.

Notable contributions include developing methodologies to mitigate instrumental systematics and foregrounds in 21cm data, as well as advancing machine learning applications for signal recovery. His group has published extensively on reionization models, power spectrum analysis, and interdisciplinary techniques combining astrophysics with statistical methods.

Students under his advisement have achieved significant milestones, including postdoc placements at institutions like the University of Chicago and Perimeter Institute. Collaborations span global initiatives, reflecting his role in advancing Canada’s contributions to radio astronomy and cosmology.
