Leadership plays a central role in business organizations, and charismatic leadership (CL) has proven to be particularly effective. Formerly poorly defined and plagued by an endogeneity problem, in the last decade the "signalling approach" has enabled the illumination of proximal components of CL. These include eye contact, facial expressions, gestures and various vocal features. However, previous research has neglected to investigate the effect of follower behaviour on CL expression, and the interaction between followers and its effects. Building on ongoing research projects, this research project therefore seeks to answer these questions. In addition to the implementation of state-of-the-art biosignal methodologies, the translation of CL into virtual environments and differently rich electronic media for group collaboration will be investigated. This should provide practical recommendations for regional and international companies that are forced to outsource and disperse their work teams.
