A regular visitor to observatories in the Atacama desert, Dr Amaury Triaud is the discoverer of over one hundred exoplanet planets (planets which orbit stars other than the Sun). His research concentrates on extracting empirical evidence about the physical processes that lead to the formation and evolution of planets. His main attention is on discovering and investigating planetary systems that are different to our own, either by the type of planets that compose those systems, by their architectures, or because of the type of star(s) they orbit.

Amaury’s current attention focuses on circumbinary planets (planets with two suns), and on identifying planets that have sizes and temperatures similar to Earth, and that orbit around the smallest stars in our Galaxy. As part of the SPECULOOS collaboration, Amaury is a co-discoverer of the TRAPPIST-1 system, whose planets are most optimal in the search for evidence of biology beyond our Solar system.

An avid communicator, Amaury enthusiastically describes recent advances in Astronomy to the public, in settings such as science festivals, astronomical associations, science museums, schools, and corporations. He reaches audiences locally, nationally, and internationally and is the editor of the TRAPPIST-1 website. Amaury searches for new means of engaging the public, and improving science interest and science literacy in the civil society.

Amaury is interested in featuring recent scientific concepts or discoveries in cultural products such as films, novels, illustrations and graphic novels; heis fascinated by the link between scientific investigations and art. He regularly comments on recent discoveries in the written press, on radio and on television.


  • PhD, Astronomy & Astrophysics, University of Geneva, 2011
  • MPhys (Hons), Astronomy & Astrophysics, University of St Andrews, 2007


Amaury’s path is an example of a modern European, born and schooled in France. He then decided to pursue his undergraduate studies at the University of St Andrew's in Scotland graduating in 2007 with a Masters of Physics, 1st class. His summers were spent in France (2003-2004), Germany (2005) and Switzerland (2006) doing research internships that nurtured his scientific career and produced his first papers. He moved to Geneva in 2007 for a four year PhD program that was completed in August 2011. The European Astronomical Association awarded him the MERAC prize for best PhD thesis on observational astronomy, defended in Europe in 2011, 2012, and 2013.

He then held research fellowships at MIT, at the University of Toronto, and at the University of Cambridge, before joining the University of Birmingham. Having already shown a wide range of research interest during this thesis at the University of Geneva, he has since continued to expand his expertise beyond his original field of exoplanets. Amaury’s research has been highlighted in numerous press releases, relayed by major news outlets worldwide.
