Chuka's doctoral research investigated the root causes of violent ethnic mobilisation in the constitutional democratic states of Africa, particularly in Nigeria's Niger-Delta region. Using the Kaufmanian ethnosymbolic theoretical framework as a guide, the project analysed the mechanism by which ethnic tensions metamorphose into full-scale violent clashes. It equally tried to shed light on why such violent confrontations often persist, despite governmental and non-governmental efforts at eradicating them.
Understanding the complex dynamics of politically salient intra-state violent conflicts is a necessary precondition for designing appropriate conflict resolution strategies. In this regard, the positive contribution of his project to political peace processes in Africa, and beyond, is not in doubt.
