About

Lucas Macri is the Dean at The University of Texas Rio Grande Valley, USA. His research primarily focuses on distance measurements in astronomy, particularly pertaining to the Hubble Constant and Cepheid variables. Recent publications include studies utilizing the James Webb Space Telescope to validate distance estimates and address the Hubble tension, as well as investigations of the metallicity of cepheids and their implications for cosmic distance ladders.
