Profile
KONNO Yoshihiko, Professor of Osaka Metropolitan University and Professor Emeritus of Japan Women's University, received the degree of a B.S. in mathematics from University of Tsukuba, Japan in 1984 and a M.S. in mathematics from the same university in 1986. He earned a degree of Ph.D. from Institute of Mathematics, University of Tsukuba in 1992. He was an assistant researcher in Institute of Mathematics, University of Tsukuba from 1988 to 1990 and a lecturer in Department of Manageing, Ishinomaki Senshu University from 1990 to 1993. He was an Associate Professor at Chiba University from 1993 to 2003 and Japan Women's University from 2003 to 2006. He was a Professor in Department of Mathematical ans Physical Sciences at Japan Women's University from 2006 to 2022. He joined the faculty at Department of Mathematics, Osaka Metropolitan University in April 2022. He also spent two months in July and August of 1994 at Department of Mathematics and Statistics, Carleton University, and a year in 1997-1998 as a visiting fellow at the Department of Statistics, University of Washington. Until now he has not received any medals and will not receive it in the future, too. KONNO is a multivariate-analysist who gets tangled up in difference product of eigenvalues and Shrinkage in Statistics. His resarch interest includes finite-sample estimation problems in multivariate analysis and non-asymptotic approach for inference theory for high-dimensional statistical models.
