My work centers on reducing the mortality and morbidity associated with ocular and periocular cancer.

I lead a clinically focused research group of about twelve investigators who run several parallel projects toward this goal. A major emphasis is uveal melanoma, the most common primary intraocular malignancy in adults. Despite enucleation, nearly 50 % of patients later develop metastases, and median survival after distant spread is only ~18 months. We can now stratify patients’ metastatic risk with high precision using a next-generation sequencing panel developed in our laboratory, yet effective preventive therapies remain scarce. Closing this gap is a core objective of my research.

Another recent advance is our deep-learning algorithm that differentiates benign pigmented fundus lesions—which occur in roughly 7 % of Caucasians—from the far rarer but life-threatening melanomas. Because benign lesions are so common, reliable triage is a genuine clinical challenge. We anticipate that targeted education plus automated early detection will enable earlier intervention and better outcomes.

I also serve as Principal Investigator of AMUM (clinicaltrials.gov), the world’s longest-running randomized trial evaluating adjuvant melatonin for uveal melanoma.

In 2026, our uveal melanoma research was ranked fourth globally in prominence over the past five years: ScholarGPS
