A problem I often encounter is deciding who to invite as co-authors. On one hand, you want to show appreciation to the people that helped you in the process of obtaining your results. On the other hand, generously adding authors will dilute the contribution of the people that made the largest contribution. In this post I would like to sketch a few hypothetical situations in which someone could be a co-author. The main goal here is to provoke some discussion on this subject, and learn about some good practices.

Introduction

Science in the 20th century has been divided into a distinct number of more or less separate disciplines ranging from Mathematics and Physics to Biology and Medicine. This distinction was naturally based on the different aspects of our material and living environment under study. In all disciplines one can clearly define ‘core’ subjects which fall in the traditional categories without any overlap with other fields. However, there is an increasing amount of research taking place at the interface or overlapping between disciplines. For a person trained in one of the traditional sciences, it can be hard to look beyond the boundaries and spot opportunities for cross-disciplinary research. This post presents some aspects of multidisciplinary research encountered when starting up a new research line.
