RESEARCH SUMMARY
My research focuses on how chromatin and transcription factor dynamics control gene expression with an emphasis on steroid hormone receptor biology. My research includes the use of genome-wide chromatin accessibility, chromatin structure, gene expression and transcription factor binding techniques in combination with cutting-edge microscopy to study the mechanisms of gene regulation. My current studies are exploring how 3-dimensional nuclear architecture, enhancer organization, and nuclear receptor interactions control gene expression.
