Research Interests

Quantitative genetics in animals (animal breeding and genetic) analyzing phenotypic data, pedigree information, and/or genomic information to select animals such as dairy cattle, beef cattle, swine, poultry, fish, and bees for improvement of production, reproduction, and health.

Background (experiences)

Dairy cattle breeding, lactation physiology, computer programming, applied statistics (biostatistics), population genetics, quantitative genetics (animal breeding and genetics).

Data analyses: dairy cattle, beef cattle, pigs, chickens, fish, bees, horses, and dogs.
