Stars are born deeply embedded in cocoons of gas and dust in dense molecular clouds. A number of factors are known to affect this process such as the nature of initial conditions as well as the feedback mechanisms. These are being investigated through multiple observations and simulations. I will give a brief introduction to our current understanding of massive star formation process including observational results that help constrain the theories. I will also present a few examples of massive star forming regions in different evolutionary stages that we have investigated in recent times, from deeply embedded protostellar objects to obscured young clusters associated with extended HII regions.
