Gem’s research is inherrently multidiscplinary, making major contributions to our theoretical understanding of diagrams and their effectiveness for human cognition. She is perhaps best known for her groundbreaking research on the development of diagrammatic logics alongside methods to automatically draw diagrams as visualizations of information. Gem has also conducted a significant body of empirical research, focusing on the graphical and topological properties of diagrams that make them effective representations. She has over 140 publications and received five Best Paper Awards at international conferences. Furthermore, she has been PI and Co-I on major grants from the UK's EPSRC and the Leverhulme Trust. As leading figure in the Diagrams community, Gem has been highly influential in the direction of diagrams-related research as well as the Diagrams conference series.  She was Program Chair and General Chair of Diagrams in 2018 and 2008, respectively, and Chaired the Diagrams Steering Committee from 2012 to 2016.
