Jonay I. González Hernández is a staff scientist, currently Head of Research, at the Instituto de Astrofísica de Canarias. He is stellar astrophysicist with several decades of experience in high-resolution spectroscopy, the study of stars in different astrophysical enviroments, and the search for exoplanets.

He  graduated in Astrophysics at University of La Laguna (ULL) in July 2001 and defended his PhD thesis on November, 2006, carried out at the Instituto de Astrofísica de Canarias (IAC), on the study of the "Chemical Composition of Stars orbiting Black Holes and Neutron Stars". His first postdoctoral contract, as “Early Stage Researcher”, was at the Observatoire de Paris-Meudon within the CIFIST (Cosmological Impact of the FIrst Stars) Marie Curie Excellence Team from 2005 to 2009, followed by postdoctoral contract at the Universidad Complutense de Madrid. He moved back to the IAC with a Juan de la Cierva fellow, followed by Severo Ochoa and Ramón y Cajal fellows. In October 2020 he got the permanent position as staff scientist at the IAC, that started officially in December 2021.

His main lines of research are :

a) search and characterization of Earth like planets;

b) search and characterization of primitive iron-poor stars of the Galaxy;

c) origin of compact objects and supernovae;

He is contributing to instrument developments of high-resolution ultra-stable spectrographs: LFC-HARPS@3.6m-ESO, ESPRESSO@8.2m-VLT, HARPS3@2.5m-INT, NIRPS@3.6m-ESO, CHORUS@10.4m-GTC and ANDES@39m-ELT. He is the Spanish representative in the Executive Board of the NIRPS and ANDES consortia, and co-I of the ESPRESSO, HARPS3, CHORUS and PLATO consortia.

He has published more than 300 (papers / citations) refereed papers (including high-impact journals such as Nature, Science, ApJ Letters, MNRAS Letters, A&A Letters), with a H-index of 68. As first author he has published more than 25 (papers / citations) refereed papers (including five high-impact publications: 1 Nature, 2 ApJ Letters, 2 MNRAS letters).
