After earning MSc degree from Isfahan University of Technology in Iran, Dr. Sargolzaei completed his PhD at Niigata University in Japan. Both degrees were in animal genetics and breeding.
In 2006, he joined the Centre for Genetic Improvement of Livestock as a postdoc. He worked on a Genomic Selection project that resulted in official implementation of Genomic Evaluation for dairy cattle in Canada in 2009. Dr. Sargolzaei has developed several novel statistical methods and software tools aiming at analysing big genomic data. The driving force behind his software developments has been his keen interest in combining new statistical methods and advanced programming techniques to put theory in practice for analysing big genomic data.
Dr. Sargolzaei has worked as a researcher in dairy cattle industry since 2009, while keeping close tie with academia. He is currently working for Select Sires Inc., the largest dairy genetics company in North America, as Director of Genetic Research and Technology.

Research Interests

Dr. Sargolzaei's main areas of research are utilization of genomic information in livestock precision breeding, investigating new methodologies to increase accuracy of predicted genomic breeding values, immunogenomics, imputation and computational genomics.
