I (David Harville) have a PhD degree (from Cornell University) and have been engaged for my entire career in teaching, research, and other activities pertaining to mathematics and statistics.  Among the areas in which I have specialized are linear statistical models and their applications in sports and other disciplines (including animal breeding).  I served for 10 years as a mathematical  statistician in the Applied Mathematics Research Laboratory of the Aerospace Research Laboratories at Wright-Patterson AFB, Ohio, for 20 years as a full professor in Iowa State  University’s Department of Statistics (where I now have emeritus status), and for 7 years as a research staff member of the Mathematical Sciences Department of IBM’s T.J. Watson Research Center.

I am the author or co-author of more than 80 research articles.  And I am the author of 3 books:  Matrix Algebra From a Statistician’s PerspectiveMatrix Algebra: Exercises and Solutions,  and (most recently) Linear Models and the Relevant Distributions and Matrix Algebra.  My work has been recognized through my election as a Fellow of the American Statistical Association and of the Institute of Mathematical Statistics and as a member of the International Statistical Institute.
