Michael G. Akritas (born 1950) is a Greek American statistician and professor emeritus of Statistics at the Pennsylvania State University.[1]

His research has focused on nonparametric statistics, factorial designs, censored data, high-dimensional data modeling, astrostatistics, and social statistics.[2]

Akritas was elected Fellow of the American Statistical Association in 2001,[3] and Fellow of the Institute of Mathematical Statistics in 2001.[4]


Akritas received a B.Sc. in Mathematics from the University of Athens in 1972, an M.Sc. in Operations Research from the University of Southampton, studied at the University of Patras under George G. Roussas,[5] and in 1978 he received a Ph.D. in Statistics from the University of Wisconsin–Madison under Richard A. Johnson.[6]


Akritas taught at MIT from 1978–1979, and again from 1980-1981 after serving in the Greek military. He then moved to the University of Rochester, and in 1985 he joined the Department of Statistics at The Pennsylvania State. He held a position at National Technical University of Athens, and visiting positions at Texas A&M University, University of Pennsylvania, Australian National University, University of Goettingen, and University of Cyprus. He co-founded, and served as Director of, the Statistical Consulting Center for Astronomy;[7] he also co-founded, and served as Treasurer of, the International Society for Nonparametric Statistics.[8] He has published 104 articles which have been cited over 4700 times.[2]
