I will talk about different populations of exoplanets and their interconnections. Specifically, I will present chemical composition measurements for hot Jupiters and directly imaged young Jovian planets, in an attempt to answer questions such as how stellar chemical composition controls planet formation, and how differences between planetary and stellar chemical abundances reveal the history of orbital migration. In addition, I will highlight recent progress in comparative planetology by contrasting (1) small planets with different densities and structures, and (2) Earth-size rocky planets with gas dwarf planets in the habitable zone. These comparative studies shed light on the origins of the diverse outcomes of planet formation and inform the search for biosignatures with current and future facilities.
