Hannu Oja
Finnish mathematical statistician (born 1950)
From Wikipedia, the free encyclopedia
Hannu Frans Vilhelm Oja (born December 17, 1950, in Jämsä) is a Finnish mathematical statistician and biostatistician known for his contribution to nonparametric inference, robust statistics, and multivariate statistical methods.[1][2] He introduced the Oja median for multivariate distributions.[3][4][5]
Education and career
Oja was born in Jämsä and studied in high school in Tampere (Tampereen klassillinen lyseo). He received his MSc in statistics at the University of Tampere in 1973 and his doctorate in 1981 at the University of Oulu under the supervision of Elja Arjas.[6][7] Oja stayed on at the University of Oulu as a lecturer after his PhD. He later moved to Jyväskylä University. He was professor of biometrics at University of Tampere's Department of Health Sciences and an academy professor at the university from 2008 to 2012. He's current a professor in mathematics at University of Turku.[1]
Oja has done research especially in the field of nonparametric statistical methods. He has also conducted applied statistical research in the fields of biometrics, signal processing, machine learning, and nutrition and health sciences. Oja became a fellow of the Institute of Mathematical Statistics in 2009.
