معرفی
Matthew Johnson is an Associate Professor in the Department of Physics and Astronomy at York University and an Associate Faculty member at the Perimeter Institute for Theoretical Physics. His research focuses on theoretical cosmology, including cosmic inflation, eternal inflation, dark energy, and confronting fundamental theories with observations of the Cosmic Microwave Background (CMB). He explores topics such as topological defects, string theory, and gravitation, with a particular interest in designing data analysis algorithms to interpret cosmological datasets.
Johnson's affiliations include York University and the Perimeter Institute. His work spans computational and theoretical approaches to understanding the universe’s origins and evolution. He collaborates widely, contributing to projects like the Atacama Cosmology Telescope and the CMB-HD Collaboration.
His research interests emphasize cosmological models, phase transitions in the early universe, and the implications of string theory’s extra dimensions for cosmology. He investigates the Multiverse concept and the dynamics of bubble universes in eternal inflation scenarios.
Johnson actively supervises graduate students in the York University Physics and Astronomy program and collaborates with institutions globally. His funding sources include NSERC, the Foundational Questions Institute, and the New Frontiers in Astrophysics and Cosmology grant program.
