Data visualizations are designed to leverage the impressive human visual bandwidth so that users can spot clusters, gaps, trends, outliers in the data within a fraction of a second. Visualizations, combined with interaction and animation techniques, can help experts interpret and explore complex data as well as gain confidence in their algorithmic results. Moreover, visualizations are highly effective tools for communicating with other analysts or stakeholders. Research on visualization involves understanding human perception and vision, visual encodings, design thinking, color choice, data simplification, interaction techniques, and animation techniques and designing the next generation of data analysis and communication tools. We have several current research opportunities available for postdoctoral researchers and PhD, master’s, and bachelor’s students.
