José María joined the BIPM in 2012, with over 30 years' experience in the field of ionizing radiation metrology. From 1992 until 2012, he was Head of, then R&D Adviser to, the Ionizing Radiation Metrology Laboratory at CIEMAT (the Spanish Centre for Energy, Environment and Technology Research). In particular he is known for the CIEMAT/NIST method to standardize beta-emitters by liquid scintillation measurements.

José María maintains a particular interest in extending the International Reference System (SIR) to beta- and alpha-emitters, and developing absolute calibration systems based on liquid scintillation techniques.
