Jiuzhou Song received his PhD degree in statistical genetics from China Agricultural University, China, in 1995. From 1995 to 1998, he held a postdoctoral fellowship in genetics at the Hebrew University of Jerusalem, Israel, and then he became a research fellow in biochemistry and molecular biology at Indiana University, USA, during 1998–2000. Currently, he works as a Professor at the Department of Animal and Avian Sciences, University of Maryland, College Park. His research centers on elucidating the genetic basis and epigenetic mechanism of genome to phenome, especially on complex diseases and quantitative traits of livestock animals and humans; developing statistical approaches to study the interaction between livestock genomes and environmental factors, especially to discover alleles and epi-alleles as biomarkers that modify responses to environmental stimuli and to investigate how such epigenetic marks and alleles affect exposed animal; global analysis of systems biology by integrating a variety of biological knowledge from genetic, genomic, and epigenetic studies; modeling and epigenetics in reprograming of chicken stem cells; and developing strategies of animal disease prevention and improving livestock performance.
