I am interested in the genetic basis of regulatory evolution.  I am focused primarily on understanding the evolution of complex cis-regulatory elements, which integrate multiple inputs from transcription factors and histone modifications to create intricate patterns of time- and tissue-specific gene expression.  I am approaching this question from two distinct angles: 1) I am analyzing histone modifications within Drosophila using ChIP-seq.  I aim to better comprehend how evolution can alter the complex patterns of histone modifications like H3K27me3.  2) I am studying interactions between transcription factors bound to the DNA, focusing on how novel TF-TF interactions can be gained and lost throughout evolution.
