I am a chemist, science educator and historian of science devoted to doing research, teaching and disseminating. My work explores the borderlands between history of science and science education, especially history of chemistry and chemistry education. Currently I work as an Excellence Visiting Researcher (Postdoc) of the Government of Mexico at the Educational Research Department of the Center for Research and Advanced Studies (DIE-CINVESTAV) of the National Polytechnic Institute (Mexico).
