Sofía Calero Diaz is a Spanish chemist who is a professor and Vice Dean of the Department of Applied Physics and Science Education at the Eindhoven University of Technology.

She attended the Complutense University of Madrid and remained there for her doctoral research, which considered the thermodynamic properties of liquids of complex molecules.

[citation needed] Calero moved to the Pablo de Olavide University (UPO) in 2003, where she was named a Ramon y Cajal Fellow, and established a group who studied nanomaterials for applications in technologies.

[4] The programme looked to developed highly efficient energy converting devices (e.g. electrochemical cells for water-splitting).

[5][6] Calero was responsible for the development of Monte Carlo simulations of the project, and contributed to the software RASPA.
