Andreas Buja is a Swiss statistician and professor of statistics. He is the Liem Sioe Liong/First Pacific Company professor in the Statistics department of The Wharton School at the University of Pennsylvania in Philadelphia, United States.[1] Buja joined Center for Computational Mathematics (CCM) as a Senior Research Scientist in January 2020.[2]

Life and education[edit]

Buja was born in Switzerland. He graduated from the Swiss Federal Institute of Technology (ETHZ, Zurich) in 1980 with a PhD in Mathematics and Statistics, where his dissertation was supervised jointly by Frank Hampel, Peter J. Huber, and Hans Föllmer.[3]

Career and research[edit]

Buja began working as research associate at ETH Zurich and Children's Hospital, until 1982. In 1982, Buja held his first academic position as an assistant professor at University of Washington, where he later became an associate professor in 1987. He also held positions in industry as a member of technical staff at Bell Communications Research and AT&T Bell Laboratories between 1994–1996 and 1996–Jan 2002, respectively. Then, he returned to academia as a professor at The Wharton School, University of Pennsylvania, where he was designated as the Liem Sioe Liong/First Pacific Company Professor in July 2003.[4]

Buja is a co-author of a data visualization system called XGobi, a predecessor of GGobi, for which Google provides more than 10,000 entries.[5] His research interests include data visualization, data mining, multivariate statistics, and nonparametric statistics. Results of his research have been discussed in multiple articles like : Science Daily,[6] Slate,[7] knowledge@wharton.[8]
