DESCRIPTION:The Hubble tension is arguably the greatest problem in modern 
 cosmology. Type Ia supernovae are central to the local measurements in mul
 tiple ways. Here\, I will talk about the analysis of the first data releas
 e of SNe Ia from the Zwicky Transient Facility (ZTF) and the ZTF-only dist
 ance ladder calibrated to the tip of the red giant branch method. This uni
 form distance ladder is a key method to control the largest sources of sys
 tematics for achieving percent-level precision on H0. \nA complementary ro
 ute to H0 is via strongly lensed SNe\, especially of Type Ia. I will revie
 w the recent work on the first resolved strongly lensed SNIa\, and the new
  discovery of SN Zwicky from ZTF. Lastly\, I will present work on the dire
 ctional dependence of the Hubble parameters and cosmic deceleration and it
 s potential implications for the H0 tension. \n
