<p class="MsoNormal" style="background:white"><span style="font-family:"Verdana",sans-serif;color:black">From a galaxy’s perspective, its environment evolves continuously over cosmic time, as it migrates from low- to high-density regions along the cosmic web.
In this talk, I will review our current understanding of how such environmental changes shape galaxy evolution, focusing on both gravitational interactions between galaxies and hydrodynamical processes involving the surrounding intragroup or intracluster medium.
I will highlight recent discoveries of galaxies caught in the act of transformation, most notably the striking “jellyfish” galaxies, which are undergoing dramatic gas stripping due to intense ram-pressure.<o:p></o:p></span></p>

<p class="MsoNormal" style="background:white"><span style="font-family:"Verdana",sans-serif;color:black">A key challenge in this field is disentangling the cumulative impact of different environmental mechanisms, especially considering that galaxies may be
“pre-processed” in groups and filaments before falling into massive clusters. To address this complexity, we are leading the CHANCES survey, a major 4MOST program designed to systematically explore galaxy transformation across a wide range of environments
and redshifts. I will present some early results and discuss future perspectives. <o:p></o:p></span></p>
