Research Summary

I am a genitourinary medical oncologist and in this capacity I specialize in caring for patients with bladder, prostate, kidney and testicular cancers. My focus is in clinical and translational research in bladder and prostate cancers, in particular the design and implementation of clinical trials for patients with these malignancies and the discovery and validation of novel biomarkers and treatment targets.
