The detections of gravitational waves by aLIGO/Virgo have opened up a new window toward the fundamental physics of our universe. This workshop aims at bringing together top researchers in the field to present recent breakthroughs, discuss on what we have learnt and what challenges we are still facing. More precisely, we focus on the following topics in this meeting: 
(1) theories beyond GR, including classical extension, and quantum gravity; 
(2) gravitational wave probe;

This workshop is under the patronage of the Jagiellonian University (Faculty of Physics, Astronomy and Applied Computer Science) and Academy of Arts and Sciences. Due to the pandemic outbreaking, it will be held on the platform of Microsoft Teams.
