Biography
Dr. Daniela Lourenco is an Associate Professor in Animal Breeding, Genetics, and Genomics at the University of Georgia in the United States. She was born and raised in Brazil, where she earned her MS and PhD degrees in animal breeding and genetics from Maringa State University. Daniela has been working in this field since 2004 and her current interests include the use of genomic information to increase rates of genetic progress, the development of methods for genomic evaluations, and the use of computational algorithms to analyze large data. She has authored over 275 conference proceedings, 162 peer-reviewed publications and 85 invited talks on five continents. She has taught several short courses and trained geneticists globally. Daniela has built a successful and solid international collaboration and has received over 40 visitors from different countries since 2015. Dr. Lourenco oversees a team of 15 graduate students and postdocs and received the UGA Fred C. Davis Early Career Award in 2020. Her research group has been working on genomic selection in beef and dairy cattle, swine, poultry, and fish. They have been involved in the development and implementation of single-step genomic evaluations for several breeding companies and breed associations. The software and algorithms developed by her group are being used for genomic evaluations worldwide.

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 in beef and dairy cattle, poultry, swine, and fish. My work comprehends finding the most appropriated methodologies, models, and strategies to evaluate livestock populations.
