This is the website of Hadley Wickham. I'm an Assistant Professor of Statistics at Rice University, interested in interactive and dynamic graphics, in developing practical tools for data analysis, and in gaining better understanding of complex statistical models through visualisation. In July 2008, I completed my PhD in statistics at Iowa State University with Di Cook and Heike Hofmann.
