The birth of Emerging Themes in Epidemiology: a tale of Valerie, causality and epidemiology

Emerging Themes in Epidemiology (ETE) is a new, online, Open Access peer-reviewed journal. The Journal is unique in that it was conceived and is managed by research degree students in epidemiology and related public health fields. The Journal's management is overseen by its Editor-in-Chief and Associate Faculty Editors, all of whom are senior members of faculty. ETE aims to encourage debate and discussion on the theoretical, methodological and practical aspects of epidemiologic research and practice. In addition, ETE is dedicated to the promotion of Open Access publication and the training of research students in the scientific publishing process. This editorial, to coincide with the launch of ETE, sets out the Journal's philosophy and aims. Epidemiology is a rich and innovative science that has much to gain from broader discussion of the causal frameworks that underpin it. ETE aims to be a major forum for such discussion.
