Lyman Alexander Page Jr.

Lyman Alexander Page Jr. is a Professor of Physics at Princeton University and a leading observational cosmologist. He co-led the Wilkinson Microwave Anisotropy Probe (WMAP) project, which revolutionized our understanding of the cosmic microwave background (CMB) radiation and the early universe. Page is also the founding director of the Atacama Cosmology Telescope project and currently serves on the Simons Observatory executive board and as an advisor at the Canadian Institute for Advanced Research.

• PhD in Physics from MIT (1989)
• Bachelor's degree from Bowdoin College

His research focuses on the CMB, dark energy, and galaxy clusters, using advanced observational techniques to study the universe's origin and composition. Over decades, his work has involved precise measurements of the universe’s expansion, structure growth, and thermodynamic properties of cosmic systems.

Notable trends in his recent publications include multi-instrument cosmological analyses (ACT, SPT, Planck), atmospheric modeling for telescopes, and studies of the thermal and kinematic Sunyaev-Zel'dovich effects. His articles often address cosmic birefringence, dark matter interactions, and galaxy evolution.
