**Bruno Leibundgut** (born 1 April 1960) is a [Swiss](/source/Swiss_people) astronomer born in [Basel](/source/Basel). His work focuses on [supernovae](/source/Supernovae) and cosmology.[1] He was a member of the [High-z Supernova Search Team](/source/High-z_Supernova_Search_Team) and participated in the planning, development and start of the operations of the [Very Large Telescope](/source/Very_Large_Telescope).

## Career

Leibundgut received his doctorate at the [University of Basel](/source/University_of_Basel) in 1988 under the supervision of [Gustav Andreas Tammann](/source/Gustav_Andreas_Tammann). His thesis was titled "Light Curves of Supernovae Type I". He was a postdoctoral researcher at Harvard working with [Robert Kirshner](/source/Robert_Kirshner) and at Berkeley with [Alex Filippenko](/source/Alex_Filippenko). He is the author or co-author of over 140 refereed papers with more than 35,000 citations.

Since 1993, he has worked as an astronomer at [ESO](/source/ESO). He has had various roles such as deputy programme scientist for the VLT, head of the user support group in Garching and Director for Science. He was on sabbatical in 2014.[2] He was the [Very Large Telescope](/source/Very_Large_Telescope) programme scientist from 2015 to 2022 and has been re-appointed director for science at [ESO](/source/ESO) in 2023.

He is an Honorary Professor at the [Technical University of Munich](/source/Technical_University_of_Munich) since 2019 [3]

He is the co-principal investigator of the adH0cc programme [4] which aims to determine the current expansion rate of the Universe, the so-called Hubble constant (see [Hubble law](/source/Hubble_law)) by measuring distances to [Type II supernova](/source/Type_II_supernova) in the Hubble flow using the Tailored [Expanding Photosphere Method](/source/Expanding_photosphere_method).

## Awards

- 2007: [Gruber Prize in Cosmology](/source/Gruber_Prize_in_Cosmology) (co-recipient with [High-z Supernova Search Team](/source/High-z_Supernova_Search_Team))

- 2011: [Nobel Prize in Physics](/source/Nobel_Prize_in_Physics) was awarded to Leibundgut's colleagues [Brian P. Schmidt](/source/Brian_P._Schmidt) and [Adam Riess](/source/Adam_Riess), from the [High-z Supernova Search Team](/source/High-z_Supernova_Search_Team) for the work done by that collaboration.

- 2015: [Breakthrough Prize in Fundamental Physics](/source/Fundamental_Physics_Prize), shared with [Brian P. Schmidt](/source/Brian_P._Schmidt), [Adam Riess](/source/Adam_Riess), and the [High-Z Supernova Search Team](/source/High-Z_Supernova_Search_Team).
