My name is Matt Baker and I’m both the owner of UsefulCharts Publishing and the designer of its posters. I live in Vancouver, Canada and hold a PhD in Education. Previously, I worked for 8 years as an expat teacher and project director in rural Sri Lanka. I've loved charts and diagrams ever since I was a young child. Like many others, I'm what you'd call a visual learner. I have found that in early grades, visual materials tend to be incorporated often. However, once a person reaches the higher grades, learning becomes almost exclusively based on reading texts and listening to lectures. There is often very little visually-based material available on more advanced subjects, particularly in the humanities.
