New Zealand-born data scientist Hadley Wickham is developing open source ways to help people collect and analyse the information that surrounds us every day.
He's yet to meet a data set he doesn't like and loves poring over his own heart rate statistics, hospital admissions data, and obscure surveys of national eating habits.
As well as revealing that bananas were by no means a common food in the 1970s, his work also helps businesses and journalists make sense of the data around them.
