Research Summary

As a urologic oncologist, my practice is primarily focused on the surgical management of individuals with genitourinary cancers. My research has been focused primarily on clinical research related to outcomes, with an emphasis on access to care and disparities in receipt of healthcare for individuals with prostate and bladder cancer.
