The rise of large, dispersed research networks operating as multiteam systems poses a major challenge to research ethics. When collaborators are spread across multiple laboratories and institutions, are grounded in different disciplines, and are working on different projects, risks of detrimental research practices and actual misconduct multiply. Yet ethical guidance has focused mainly on the micro level of individual investigators or the macro level of societal implications, leaving a gap at the intermediate level of the research network itself. Prof. Wolf has led a project funded by the National Science Foundation to analyze these problems and propose solutions. The NetEthics project has developed guidance and tools to help research networks and their leaders assess the ethical issues facing the network to advance ethical and responsible research.
