David L. Collinson is a UK-based scholar of gender, organizations and management, with a special interest in leadership. Collinson can rightly claim to be amongst a small number of top-flight European scholars in his field. His range of work on critical approaches to leadership, management and organization is vast and variegated, with primary interests in: leadership and followership dialectics; power, identities and insecurities; gender, men and masculinities; conformity, dramaturgy and resistance; humour in organizations; and positivity and Prozac leadership. In particular, he has focused much of his academic work on two related subject areas, leadership, and gender, men and masculinities, thus bridging Critical Leadership Studies (CLS) and Critical Studies on Men and Masculinities (CSMM).
