Hubble tension in cosmology

The Hubble constant (H0) is a key parameter in cosmology that sets the expansion rate of the Universe.  Independent determinations of H0 are important to ascertain the possible need of new physics beyond the standard cosmological model, given the tension in current H0 measurements.  I will review the H0 measurements from different techniques, with a particular focus on strong gravitational lensing.  I will show the bright prospects of strong lensing as an independent and competitive cosmological probe.
