Alfredo Yegros, PhD

Alfredo Yegros is a senior researcher at the Centre for Science and Technology Studies (CWTS) of Leiden University in the Netherlands. He is a member of the Engagement & Inclusion focal area .

His research revolves around quantitative studies of science, technology and innovation. His specific research interests embrace, among others, public-private interactions and knowledge flows, science-technology linkages, and relationship between science/technology and innovation.

Alfredo Yegros also performs contract research through CWTS B.V., for a wide range of national and international clients. The participation in externally funded research projects is also one of his main areas of activity, including projects funded by the European Commission such as Identification of key technology domains project (KeyTech), Knowledge in the making in the European society (KnowMak), Research infrastructures for the assessment of science, technology and innovation policy (RISIS) and U-Multirank, as well as past projects like Nanodata or University-Industry Cooperation in Europe. Both, bibliometric and patent analyses, play a central role on his contribution to contracts and research projects.

Within Alfredo Yegros is also member of the CWTS project board (IPB), contributing to the management of research projects conducted by CWTS.

Alfredo Yegros has an MSc in Information Science (2002) – Universitat de València and Universitat Politècnica de València and he holds a PhD in Information Science, Universitat Politècnica de València (2012). Within the framework of his PhD he visited the Science and Policy Research Unit (SPRU) at the University of Sussex.

Before joining CWTS, Alfredo worked during more than ten years at the Spanish National Research Council (CSIC), first at the Technology Transfer Office of CSIC in Valencia and then at the Institute for Innovation and Knowledge Management INGENIO (CSIC-UPV).
