The explosive data influx from multi-messenger missions has provided valuable clues on the origins and evolution in the cosmos over vast ranges of space and time. While competing processes lead to apparent diversities, some common physical effects basically determine the evolutionary destiny and observable properties of the Solar System, exoplanets, Galactic center, AGNs, and gravitational-wave generators.  I will present some theoretical commonalities between these astrophysical entities in the contexts of: 

1) structure and evolution of gaseous disks, 

2) emergence of sub-entities, such as dust, planets, and stars, and 

3) dynamical evolution of residual satellites after disk depletion.  

I will highlight some key observations which may provide some stringent constraints on scenarios of coevolution between massive black holes/exoplanets with their respective host environments.

His principal research interests are in the origin of the solar system, star formation, astrophysical fluid dynamics, dynamics of stellar clusters, structure of galaxies, active galactic nuclei, and galaxy formation. Another area of Prof. Lin's research is development of a theory for the formation of first-generation stars in globular clusters and galaxies.
