Clinical/Research Interests:

The research in my laboratory is driven to provide insights into the development and progression of prostate cancer—a process which is inextricably linked to androgen receptor signaling, with the ultimate goal of developing more effective diagnostic, prognostic and therapeutic strategies for prostate cancer. We are focusing on the following areas:

  • Androgen receptor and co-regulators in prostate cancer progression
  • Androgen signaling and therapeutic resistance
  • Tumor suppressors in Prostate cancer
  • Understanding the link between development and cancer
