Research Focus

Our lab is focused on the biological questions that genomic mosaicism can help us answer. From a fertilized egg, all our cells constantly acquire mutations. Our body repairs most mutations, but some mutations remain in our genome and get passed from cell to cell during embryonic development, upon tissue self-renewal, or after environmental exposure. The distribution of these mutations leads to the phenomenon of genomic mosaicism. We developed DeepMosaic (Yang et al., Nat Biotech 2023), MosaicBase (Yang et al., GPB 2020), and other computational resources to understand genomic mosaicism. We are interested in the impact of genomic mosaicism in the father's sperm on the offspring, such as the life-long impact on their genetic health (Yang et al., Cell 2021), or how the environment and behavior are shaping the mutational landscape. We would also like to use genomic mosaicism as a 'genetic paint' to trace back human development in different tissue and cell types both in normal conditions (Breuss et al., Nature 2022, Chung et al., Nature 2024) and disease settings.
