I decline all review requests with short deadlines, from journals requiring payment from authors, or those that breach the implicit boundaries of conflict of interest in peer review. This includes submissions from close collaborators, students, or researchers with whom I have personal disagreements or scientific divergences.

Current PhD students

A crucial career step in developing independence is the PhD period, during which students are trained by their supervisors to become independent researchers, Studies in Higher Education (2024).
