Dr. William M. Muir attended the University of Illinois where he received both his B.S. in Conservation Biology and M.S. in Quantitative Genetics, and Purdue University where he received a Ph.D. in Population Genetics. He is Professor Emeritus at Purdue University, Department of Animal Sciences, and has held positions at the University of Kentucky Department of Statistics, and Indiana University School of Medicine. He is the recipient of the Animal Well- Being Award, American Poultry Science Association, Merck Research Award for Achievement, and Certificate of Excellence from the Council for Agricultural Science and Technology; served on the National Academy, National Research Council on Animal Biotechnology. He is an internationally recognized authority in poultry breeding and genetics. He has over 200 peer reviewed publications, 3 in PNAS, 1 in Science on Line, and edited the book Poultry Genetics, Breeding, and Biotechnology. He was the first to demonstrate that "group selection" is an effective breeding method to address animal welfare concerns in poultry while at the same time improving productivity. He further developed methodology to estimate an animal's competitive, or indirect genetic effect, on group productivity and thereby provided generalized breeding methods to address competitive issues in both animal and plant breeding programs. His work is frequently quoted in a wide variety of news media outlets, including Nature, NOVA, NPR, the Evolution Institute, Forbes, the Today Show, USA Today, BBC News online. A TED Talk by the management expert Margaret Heffernan was the first person to apply the lessons of Muir’s research directly to the human workplace. His “Superchicken” model, featured in “Down with the Pecking Order – Geneticist’s Superchicken Research Takes Flight as a Metaphor for Effective Team Management, can be found on Wikipedia. He also developed methodology for biotechnology risk assessment of genetically modified organisms thereby providing government agencies, industry, and environmentalists with objective assessments of risk for the protection of the environment while promoting responsible use of biotechnology.

Prof. Michael Goddard graduated in Veterinary Science and received his PhD for research on the genetics of guide dogs for the blind, both from the University of Melbourne, Australia. He has worked at James Cook University and the University of New England and is currently Professorial Fellow in Animal Genetics at the University of Melbourne. His research has been in the genetic improvement of livestock especially dairy and beef cattle. In 2001 he was a co-author on the first paper (Meuwissen et al., Genetics) to describe how to estimate breeding values using a genome-wide panel of DNA markers to (genomic selection). Genomic selection has now been widely adopted in livestock and crops. In 2010 he was a co-author on a paper (Yang et al) that found that when the variance was estimated using all SNPs (single nucleotide polymorphisms) simultaneously, most of the "missing heritability" in complex traits of humans was explained. Prof. Goddard is a Fellow of the Australian Academy of Science and the Royal Society (London), and the recipient of the 2016 Carty Award of the USA National Academy of Sciences.

State of the art in genomic prediction of beef cattle performancevideo

Professor Garrick's research goal is to understand genetic and environmental factors affecting variation in quantitative (or complex) traits of agriculturally important animals. He has had extensive experience in Oceania, the USA, and other countrie in the design of efficient animal breeding programs.

Dr Garrick's current research projects aim to improve the accuracy of predicted genetic and phenotypic merit using high-density genomic information. Generally, his work focuses on the portfolio of endeavors that are involved in the design and implementation of genetic improvement programs. These include aspects of genetics, economics, statistics, and biology. Attention is directed at variance component estimation, prediction of breeding values, development of breeding objectives, exploitation of breed/heterosis effects, and breeding industry structure; primarily in regard to their application to the nationa improvement of beef cattle, but other species are also considered in his work.

Dr Garrick has received numerous recognitions and is a member of the American Dairy Science Association, the American Society of Animal Science, the New Zealand Society of Animal Production, and the Association for the Advancement of Animal Breeding & Genetics.

Systems Genetics of Drosophila Complex Traits video

Professor Mackay’s research goal is to understand genetic and environmental factors affecting variation in quantitative (or complex) traits. This is necessary for risk modification of multifactorial human diseases, in theory for a more comprehensive view of the genetic processes underlying phenotypic evolution, and in practice for improving production traits in domestic species. Professor Mackay investigates the genetic architecture of quantitative traits by studying: (1) at what genetic loci (Quantitative Trait Loci, QTL) segregating and mutational variation occurs; (2) homozygous, heterozygous and epistatic effects, pleiotropic effects on other characters, including fitness; and environmental sensitivities of QTL alleles; and (3) the molecular genetic basis of quantitative variation in nature. Current research focuses on Drosophila melanogaster, which has a wealth of genetic and genomic resources, and morphological, behavioral, physiological and life history characters spanning the gamut of fitness profiles.

During her career, Dr. Mackay has received numerous recognitions, including: Fellow, American Association for the Advancement of Science (2003), Genetics Society of America Medal (2004), Fellow, American Academy of Arts and Sciences (2005), Fellow, Royal Society (2006), Member, New York Academy of Sciences, (2007), and Member, National Academy of Sciences (2010). Apart from having published numerous scientific articles in her areas of interest, she is a co-author of Falconer’s celebrated “Introduction to Quantitative Genetics”, a landmark textbook.

Professor Sorensen has made very strong contributions to quantitative and statistical genetics. In the 80’s he introduced best linear unbiased prediction in the national pig breeding program of Denmark. Subsequently, he pioneered the use of Markov chain Monte Carlo in quantitative genetics, and made an important contribution via the widely cited book “Likelihood, Bayesian and MCMC methods in quantitative genetics”, Springer, 2002. He has lectured extensively in Bayesian methods and Markov chain Monte Carlo sampling in many countries. In 2009 he was elected Fellow of the American Statistical Association (USA) for “influential research in statistical methods for quantitative genetics; for pioneering work on Bayesian methods applied to animal breeding; and for excellence in international teaching of advanced statistical methods”. His current research has focused on quantitative genetic models for investigating genetic control of environmental variability. Outside interests include philosophy, classical music and tomatoes.
