We are deeply saddened to announce the death of Mr Jacome Costales Ballesteros on 10 August 2023.

Jacome Costales Ballesteros, who was born on 29 April 1999, worked in the FAP department and had been at CERN since 1 October 2021. 

Yaco, as his colleagues called him, was a talented software engineer, a person with a great heart and a kind and gentle character. His colleagues in the Business Computing Group were shocked by his sudden death and will greatly miss him both as a wonderful colleague, a partner in adventure, and a great friend to many.

The Head of the Human Resources department has sent a message of condolence to his family on behalf of the CERN personnel.
