Prof.dr. Robert Tijssen

Robert Tijssen holds the Chair of Science and Innovation Studies. He coordinates the Science, Technology and Innovation Studies (STIS) research program at CWTS.

Robert is affiliated to the African Studies Centre at Leiden University and he is a project leader at the LDE Center for Frugal Innovation in Africa. His ties to Africa include a professorship at Stellenbosch University (South Africa), and board membership of South Africa’s DST-NRF Center of Excellence in Scientometrics and Science, Technology and Innovation Policy.

He is also an international research partner and co-investigator at the Centre for Global Higher Education (United Kingdom).

His scholarly interests and research activities focus on various topics within science and innovation studies, as well as related issues in the area of higher education studies. Most of his academic studies within this ‘knowledge triangle’ tend to be empirical and quantitative.

The current research portfolio includes work on research cooperation, world university rankings, university-industry interactions, socioeconomic impacts of science, but also region-specific topics such as university-developed inclusive innovations in Africa, research excellence in the Global South, and China’s New Silk Road Initiative.

Robert is the CWTS project manager of U-Multirank, an open source information platform on the performance of higher education institutions across the globe.

Robert’s activities extend into science policy and research management. Most of his advisory and consultancy portfolio relates to monitoring and evaluation of university R&D performance, with a strong focus on the development and application of analytical tools and indicators in the context of quality assurance systems, reward and incentive systems, knowledge transfer mechanisms, and commercialization of university research. The work includes indicator-based assessments of research programs, and developing evaluation systems of regional innovation impact by universities.

Google Scholar Citations provides an overview of his academic research output and scholarly impact, comprising more than 150 publications with a total of some 6 000 citations.
