In his research, Christopher explores different patterns of corporate social responsibility implementation in globally integrated companies, paying particular attention to how firm size influences the way companies organize CSR. Furthermore, Christopher has been studying a range of phenomena under the umbrella of CSR, such as the evolvement and diffusion of CSR standards, the influence of organizational identity orientation on the implementation of CSR practices, or the prevalent mismatch between CSR “talk” and CSR “walk” in small and large firms. Furthermore, he has investigated dynamics at the individual level of analysis by looking at CSR professionals inside large corporations and their concomitant struggles when selling CSR issues intra-organizationally. Christopher is also interested in Critical Management Studies (CMS), philosophy of science, business ethics, and social entrepreneurship. In 2019, he published a book with Cambridge University Press, "Corporate Social Responsibility (Elements in Business Strategy)", which provides a critical introduction to contemporary approaches to CSR.
He is also affiliated with Makerere University Business School in Kampala, Uganda, where he is involved in different research and capacity-building projects that aim to promote local CSR initiatives in rural agricultural value chains, as well as in a project aimed at fostering educational reforms in Ugandas higher education sector.
Christopher’s research has appeared in journals such as Academy of Management Discoveries, Business & Society, Harvard Business Review, Human Relations, International Journal of Management Reviews, Journal of Business Ethics, Journal of International Business Studies, Journal of Management Studies, Organization & Environment, Organization Studies, and Strategic Organization, as well as in several book chapters. He is currently General Editor of the Journal of Management Studies.
