Research Topic: Transcriptional bursting is the cycling of genes between highly transcribing and non-transcribing states that is conserved in all cells. I aim to determine how the dynamics of transcriptional bursting are affected by histone post-translational modifications (eg. acetylation, methylation). I use the Drosophila Gap Genes as a model system and determine the dynamics of the promoter states of these genes using quantitative imaging and mathematical modeling.
Teaching Interests: Cell Biology, Development, Genetics, Transcriptional Regulation, Quantitative Imagining, Stem Cells and Differentiation, General Biology
