Dr. Dekkers (co-)teaches Quantitative and Populations Genetics (AnS561) and Animal Breeding Strategies, (AnS 652), in which the basic concepts and advanced issues in design, evaluation, and optimization of genetic improvement programs for livestock populations are presented and discussed.

Dr. Dekkers' areas of research are quantitative genetics and animal breeding with application to swine and poultry genetics, including utilization of molecular genetic and genomic information, QTL detection, gene expression data analysis, marker-assisted selection, design, optimization and economic aspects of breeding strategies, and genetic aspects of residual feed intake in pigs.
