Throughout a degree in business Peter frequently encountered the power of data visualisation but it was not until the application process for the Data School that a whole new world was opened with the introduction to Tableau.
After a brief experience in the world of sports data collection, Peter unearthed a keen interest in the potential to guide understanding and tell stories through data analysis. The chance to join the Data School straight from university was not to be missed and he is excited to learn from the best in the data visualisation business.
