Jose-Manuel Diego-Mantecón studied pure mathematics at the Royal Holloway University of London and received his M.Phil. and Ph.D. degrees in mathematics education from Cambridge University (UK). He has a large experience in managing international projects and evaluating comparative studies. He was part of the Millennium Mathematics Project (MMP) at the University of Cambridge, directed by the theoretical physicist and mathematician John Barrow. As part of the MMP, Jose was also responsible for the Spanish version of the Maths Thesaurus Project— a multilingual and interactive maths dictionary. In 2012 Jose developed a consistent instrument to evaluate student mathematics-related beliefs in Spain, Slovakia, Ireland, England, and Cyprus (Diego-Mantecón, 2013). Jose has collaborated with the TIMSS project, being the Spanish representative for designing the mathematics items for TIMSS 2015. Nowadays, Jose participates in five international STEM-related projects: KIKS (Erasmus +), STEMforYouth (H2020), EduLarp (Erasmus+), STEAMTeach (Erasmus), and Aut0Math (Erasmus +). He is also director of the Mathematics, Statistics, and Computation Department at Universidad de Cantabria and head of the Open STEAM Group: https://www.opensteamgroup.unican.es/
