DESCRIPTION:Probing gravity and dark energy in the era of multi-messenger c
 osmology.\n\n\n It is now an exceptional time for modern cosmology\, when 
 we can observe the universe with high precision and connect cosmological m
 easurements with theory. The excitement about the advances of observationa
 l cosmology is accompanied by the awareness that we face a mix of long sta
 nding challenges (nature of dark matter\, dark energy and the physics of i
 nflation) with deep roots in particle theory and gravity\, as well as new 
 tantalizing "curiosities". I will focus on the challenge posed by dark ene
 rgy and the quest of testing gravity on cosmological scales. I will discus
 s recent progress in identifying the optimal theoretical framework to tack
 le these in the context of large scale structure missions as well as direc
 t detection of gravitational waves. I will also address the so-called Hubb
 le tension\, and present some recent work where we have explored it "from 
 first principles".
