WELCOME
My name is Haiyang Wang. I have recently moved to the University of Copenhagen as an Assistant Professor of Planetary Science . So, this site has been archived.
My research domain is in (exo)planet science. I am interested in a broad range of topics such as how the solar system and other planetary systems formed and how their various internal bodies are connected in terms of both physics and chemistry. I have also been developing models (e.g. the volatility trend and the ExoInt code ) to characterize the compositional similarities and differences between stars and planets and to constrain the interior composition and structure of exoplanets. My ultimate goal is to understand habitable worlds including and beyond our own and hence advance Earthlings' future on the "Pale Blue Dot" and elsewhere in the Universe.
In brief, I identify myself:
An exoplanetologist passionate about interdisciplinary studies pertaining to planets and life
With demonstrated research experience in multi-disciplinaries: planetary astrophysics, cosmochemistry, and geophysics
With expertise in numerical modelings of the formation, compositions, interiors and atmospheres of rocky exoplanets
An explorer of chemical fingerprints of habitable worlds within and beyond our Solar System
