  • Research Interests -
    • Repetitive DNA landscape of the avian genome: Birds are unusual in the sense that they have one of the smallest genomes among vertebrates with only about 15% repetitive DNA. We have characterized the repetitive DNA fractions generated by Cot-based sequencing and discovered several new transposons as well as adding 5 new family members to the non-LTR retrotransposon, CR1. This work will continue by analyzing additional avian genomes in a wide range of clads to discover when each element entered the genome. Development of the hen oviduct as a bioreactor for the production of exogenous proteins in egg whites: Current emphasis is on developing methods to modify the chicken genome via transgene addition and gene targeting and includes identification of growth factors and cytokines involved in avian germ cell emergence and development.
