Pier-Emmanuel Tremblay

I am Associate Professor in the Astronomy and Astrophysics group and European Research Council (ERC) Starting Grant fellow. From 2021, I have been awarded over €1.9 million part of a new ERC Consolidator Grant, from which I will have several funded PhD projects and postdoc positions available. Please contact me if you would like to find out about opportunities to work within my research group. If you wish to apply for an independent postdoc fellowship, please visit our fellowship opportunities.

WDI am interested in white dwarfs and stars as physics laboratories and probes of Galactic and planet formation history. I develop model atmospheres and 3D radiation-hydrodynamical simulations and work with large data sets from Gaia and multi-object spectroscopic follow-ups from 4MOST and WEAVE. Recently we have discovered the first direct evidence of solid white dwarfs (Nature, 9 January 2019), a massive star with a bizarre atmosphere could be two white dwarfs that merged together (Nature Astronomy, 2nd March 2020), the source of carbon in the Universe (Nature Astronomy, 7 July 2020) and definitive evidence of ancient terrestrial planet crusts (Nature Astronomy, 11th February 2021).
