Hari Iyer was born in Chennai (then known as Madras), India. After graduating from high school he joined St. Xavier’s college in Mumbai and completed his B.Sc degree in Mathematics in 1970. Subsequently he attended the University of Notre Dame in Indiana and completed his MS and his PhD degrees in Mathematics (Theory of Finite Simple Groups) under the direction of Professor W. J. Wong. He was an instructor of Mathematics at the University of Utah from 1975 to 1977.
In June 1977, Hari decided to work with Professor Raj Chandra Bose in the field of Experimental Design, at Colorado State University, and received his PhD in Statistics in 1980. Immediately following this he joined the faculty in the Department of Statistics at Colorado State University in 1980.
During the past few years he has collaborated with Jack Wang, Thomas Mathew, Paul Patterson, Jan Hannig, and many of his PhD students, focusing on Fiducial Inference, an inference approach originally introduced by Sir Ronald A. Fisher in the 1930s.
Hari has been a faculty visitor at the National Institute of Standards and Technology (NIST) for nearly 25 years. During the recent years Hari, collaborating with Jack Wang and Jan Hannig, has contributed to research related to quantification of uncertainty as proposed in the Guide to the Expression of Uncertainty in Measurements (GUM). Much of this research is based on Fiducial Inference Methodology.
