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

Disease progression patterns and association of prostate-specific antigen level with risk of progression in nonmetastatic castration-resistant prostate cancer.

Journal article Prostate Cancer Prostatic Dis · October 2026 BACKGROUND: In ARAMIS, darolutamide statistically significantly prolonged metastasis-free survival by 2 years and reduced the risk of death by 31% in patients with nonmetastatic castration-resistant prostate cancer (nmCRPC). We report post hoc analyses of ... Full text Link to item Cite

Recruitment strategies in the PROMISE Registry: Evaluating institutional outreach, direct-to-patient marketing, and community engagement approaches in a decentralized germline genetic registry.

Journal article Contemp Clin Trials Commun · October 2026 PURPOSE: The PROMISE Registry is a U.S. decentralized, 20-year prospective prostate cancer germline genetic registry. Here, we examine the effectiveness of different recruitment strategies, including institutional partnerships, direct-to-patient marketing ... Full text Link to item Cite

External validation of the NADIR model for early prostate-specific antigen response prediction in enzalutamide-treated metastatic hormone-sensitive prostate cancer: An analysis of the ARCHES trial.

Journal article Cancer · October 1, 2026 BACKGROUND: Early favorable prostate-specific antigen (PSA) response to ≤0.2 ng/mL by 6 months is associated with superior overall survival (OS) in metastatic hormone-sensitive prostate cancer (mHSPC).
