Research Summary

We investigate how stem cells are regulated to regenerate missing tissues. We study the cellular events involved in this process and the attendant roles for regulatory genes that control regeneration steps. We utilize an array of methodologies, including high-throughput sequencing, RNA interference (RNAi) screening, and numerous assays and tools for phenotypic analysis to characterize regeneration regulatory genes.
