Papers mills and other manipulative practices are a major problem in the scientific publishing system. Addressing this problem requires an in-depth system-level understanding of dynamics leading to these practices. At @cwts we have PhD position to work on this! https://www.universiteitleiden.nl/en/vacancies/2025/q2/15601-phd-candidate-paper-mills-and-systematic-manipulation-in-research-publishin
