Clara Calero-Medina, PhD

Dr. Clara Calero-Medina is a senior researcher at the Centre for Science and Technology Studies (CWTS) of Leiden University in the Netherlands. She has a background in Economics, and Science and Technologies Studies. As a researcher her work is related with network analysis applied to scientific publications, particularly citations and co-authorship networks for the study of research performance. Clara has published numerous papers related with these issues. Another line of her research is related University Rankings. Finally she is also involved in the CWTS research team ‘ Society using research Evaluation’.  At CWTS, Clara is also coordinating and managing the different contract research projects carried out at the institute.
