GSRB1 Room 3006, 905 La Salle St, Durham, NC 27710

Overview


I am a clinical and translational investigator focused on precision therapies and biomarkers in advanced prostate and other GU cancers.  I oversee a large research team of clinical and lab based investigators focused on improving patient outcomes, preventing metastatic disease, and understanding the biology of aggressive prostate cancer.  Some key themes:
1. Predictors of sensitivity and clinical efficacy of therapies in advanced prostate cancer
2. Novel designs of clinical trials and pharmacodynamic/translational studies in prostate, kidney, bladder cancer
3. Pre-operative models for drug development of novel agents in human testing in prostate cancer
4. Novel therapies and drug development for prostate, renal, bladder, and testicular cancer
5. Design of rational combination therapies in men with metastatic hormone-refractory prostate cancer
6. Developing prognostic and predictive models for progression and survival in metastatic prostate cancer
7. Examining surrogate markers of mortality in metastatic prostate cancer
8. Biologic basis for prostate cancer lineage plasticity, immune evasion, hormone therapy, and metastasis

Journal Article Cancer Med · January 2026 BACKGROUND: Darolutamide plus androgen-deprivation therapy (ADT) improved metastasis-free survival (MFS) by 2 years and reduced the risk of death by 31% in nonmetastatic castration-resistant prostate cancer (nmCRPC) in ARAMIS. Prior local therapy may influ ... Full text Link to item Cite
