Identity design for Biomedical Research Centre, which belongs to the Barcelona University. The client expressed the need of being easily related with the University, represented by the letters 'U' and 'B' into two spheres. The first initiative was the observation of their work area visiting their laboratories. We observed their routines, mechanisms and tools, and among many different devices able to generate inspiration for graphic elements, finally we find a school board with all the formulas, which represent their daily research. The solution was to create a graphic system based in the usual symbology of their formulas, adding the initials IBUB into spheres, based on the typeface Neuzeit, which recalls the logo of Barcelona University.
