Our major research interests lie in understanding the transcriptional and cis-regulatory mechanisms underlying Hedgehog signaling during embryonic development and cancer. Our experimental approach is centered on the mouse model system, where we employ a combination of genetic, molecular and genomic approaches.

Our current efforts are focused on two major questions:

  • How do transcription factors mediate Hedgehog signaling?
  • How are multiple signaling pathways integrated at the transcriptional level?
