Title: Resolved Observations and Modelling of the Formation of Massive Stars in Clusters

Abstract: Radio interferometric observations are key to our current understanding of the formation of massive stars in clusters, but often the interpretation is limited by the complexity of observations. First, I will present recent projects aiming at measuring the population of star-forming cores and young massive stars in cluster forming clouds, mainly the ALMA-IMF Large Program and a complementary project in the W49 cloud. I will highlight some of the first scientific results of these programs, and describe the public data releases of ALMA-IMF. For the interpretation of the continuum images, the separation of dust and free-free emission is very important, so I will also discuss a few methods to achieve this. Then I will switch to describe other projects consisting in modelling the dust and free-free continuum, as well as the kinematics in radio recombination and molecular lines of massive (proto)stars in clustered environments. Finally, I will outline our initial efforts to contribute to the science case of the Next Generation Very Large Array, which ideally should have a few antennas across Mexico.
