    Collapse Overview
    We are interested in the mechanisms that underlie epigenetic memory of cell fate decisions. Chromatin modifications facilitate the regulation of differential expression of key control genes required for cellular differentiation. Diverse chemical modifications of nucleosomes and DNA play a fundamental role in gene regulation, shaping DNA accessibility and signaling to maintain gene expression states.

    We study the dynamic regulation of chromatin modifications and how these marks contribute to epigenetic inheritance of gene silencing. Our lab uses synthetic biology approaches in mouse embryonic stem cells to manipulate chromatin modifications and study their dynamics and inheritance.

    Altmetrics Details PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
