BIDS hosted the first annual Graphs Across Domains (GraphXD) Workshop on March 27–29, 2018.

Introduction: Graphs arise in many fields. A sociologist interested in social interactions in a community may record their observations in a graph of individuals connected by friendship. A geneticist interested in how genes are co-expressed may represent their data as a graph of genes with edges connecting genes that are expressed together. An online airline purchasing system may use a graph of airports connected by edges with direct flights between them.

Progress in understanding graphs and developing new graph algorithms in a number of diverse fields is hindered by the fact that researchers who use them typically don’t have the opportunity to communicate with others who work on similar problems in different domains.

**Graphs and Complex Networks Across Domains (GraphXD)** connects scientists, researchers, and theorists interested in graphs from a variety of fields through seminars and workshops. This is the inaugural workshop.
