Description of Research Interests
The increasing availability of genomic information for nearly all livestock species have led to increased interest in using this information to help selecting the best animals in genetic improvement programs. The genomic selection has been associated with additional accuracy in estimating breeding values and reduction in generation intervals, which lead to higher and faster genetic gains. However, the genomic response may be different depending on the species and the population structure, and the genomic strategy may be still unclear in some cases. My research has been focused on improving livestock production using genomic information, and addressing issues related to the implementation of genomic selection mostly in beef and dairy cattle and secondly in poultry and swine. My work comprehends finding the most appropriated methodologies, models, and strategies to evaluate livestock populations.
