Education Doctor of Philosophy, The Ohio State University: 1970 Master of Science, The Ohio State University: 1967 Bachelor of Science, Delaware Valley College: 1965
Instruction Dr. Berger teaches computer techniques for biological research ((AnS 500), and population dynamics in animal breeding (AnS 550).
Research Dr. Berger's areas of research are high performance scientific computing procedures that contribute to the genetic enhancement of livestock; genetic evaluation of animals on a national basis, as well as research into the development and improvement of these evaluations; and scientifically acceptable models for parameter estimation, prediction of breeding values and analysis of data sets that service the livestock industry.
