PROJECT NARRATIVE Recent progress in complex trait genetics, coupled with the technical ability to generate accurate genome-wide genotypes from single-cell input, has made it possible to genetically screen embryos for common polygenic traits and disease risk. However, little empirical work has been done to quantify the utility of polygenic embryo screening (PES), examine its ethical implications, and assess stakeholder perspectives. The proposed study is designed to provide the necessary empirical basis for informed ethical discussion.

The long-term objective of this Pathway to Independence Award (K99/ROO) is to train to become an independent researcher in bioethics with a strong interdisciplinary foundation in genetics and epidemiology. My research plan is to characterize ethical and social issues in genetic studies of complex traits and evaluate how and whether they differ from those in genetic studies of Mendelian traits. This research will enable current and future complex disease researchers and policy makers to understand and address these issues proactively.
