Helen Wall is a power user of Microsoft Power BI, Excel, and Tableau. Her primary driver behind working in these tools is finding the point where data analytics meets design principles, thus making data visualization platforms both an art and a science. She considers herself both a lifelong teacher and learner.
She is a LinkedIn Learning instructor for Power BI courses that focus on all aspects of using the application, including data methods, dashboard design, and programming in DAX and M formula language. Her work background includes an array of industries, and in numerous functional groups, including actuarial, financial reporting, forecasting, IT, and management consulting.
She has a double bachelor’s degree from the University of Washington where she studied math and economics, and also was a Division I varsity rower. On a note about brushing with history, the real life characters from the book The Boys in the Boat were also Husky rowers that came before her. She also has a master’s degree in financial management from Durham University (in the United Kingdom).
