Haiyang S. Wang


My name is Haiyang Wang. I am a postdoctoral fellow in Exoplanets and Habitability Group at ETH Zurich and also a member of the NCCR PlanetS by mainly working on the characterization of terrestrial-type extrasolar planets.

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

Career/Life News

September 2022

I was invited to participate in the Lorentz Center Workshop: The Diversity of Rocky Planets 2022 and also gave a joint lecture (together with Hiroyuki Kurokawa and Allona Vazan) on Planet formation and volatile delivery.

I convened and hosted a session Devolatilization During Rocky (Exo)planet Formation: Mechanisms, Simulations, and Observations together with other colleagues at EPSC 2022.

Apart from that, I also gave two talks at EPSC 2022, respectively, on:

The interior diversity of terrestrial-type exoplanets: constrained with devolatilized stellar abundances and mass-radius measurements

No universal devolatilization trend has been found for the solar system rocky bodies
