He is thechief scientist atPosit PBC and an adjunct professor of statistics at theUniversity of Auckland,Stanford University, andRice University. His work includes thedata visualisation systemggplot2 and thetidyverse, a collection ofR packages fordata science based on the concept oftidy data.
Wickham was born inHamilton, New Zealand. He received a Bachelors degree inHuman Biology and a master's degree in statistics at theUniversity of Auckland in 1999–2004 and hisPhD atIowa State University in 2008 supervised byDi Cook andHeike Hofmann.[2][4] He is thechief scientist atPosit PBC (formerly RStudio PBC)[5] and an adjunct professor of statistics at theUniversity of Auckland,Stanford University, andRice University.[6][7][8]

In 2006 he was awarded theJohn Chambers Award for Statistical Computing for his work developing tools for data reshaping and visualisation.[12] Wickham was named a Fellow by theAmerican Statistical Association in 2015 for "pivotal contributions to statistical practice through innovative and pioneering research in statistical graphics and computing".[13] Wickham was awarded the internationalCOPSS Presidents' Award in 2019 for "influential work in statistical computing, visualisation, graphics, and data analysis" including "making statistical thinking and computing accessible to a large audience".[14]
