Christopher Marland

Chris studied history at the University of Edinburgh, along with an Erasmus year at La Complutense in Madrid, specialising in economic and financial history. Having never done any type of data visualisation, Chris never considered a career in data until he met The Data School at a careers fair. Within days, Chris had become a Tableau addict and decided to apply.

What inspires Chris about data analysis and visualisation is the inherent liberalism that lies underneath; his professional mission is not only to provide insights, but to empower people with the tools to create their own.
